cbe0b3af73 media: ov8865: Disable only enabled regulators on error path
If powering on the sensor failed, the entire power-off sequence was run
independently of how far the power-on sequence proceeded before the error.
This lead to disabling regulators and/or clock that was not enabled.

Fix this by disabling only clocks and regulators that were enabled
previously.

e15ddc9644 media: i2c: Switch exposure control unit to lines
The ov8865 driver currently has the unit of the V4L2_CID_EXPOSURE control
as 1/16th of a line. This is what the sensor expects, but isn't very
intuitive. Switch the control to be in units of a line and simply do the
16x multiplication before passing the value to the sensor.

The datasheet for this sensor gives minimum exposure as 2 lines, so take
the opportunity to correct the lower bounds of the control.

295786e535 media: i2c: Update HTS values in ov8865
The HTS values for some of the modes in the ov8865 driver are a bit
unusual, coming in lower than the output_size_x is set to. It seems
like they might be calculated to fit the desired framerate into a
configuration with just two data lanes. To bring this more in line
with expected behaviour, raise the HTS values above the output_size_x.

The corollary of that change is that the hardcoded frame intervals
against the modes no longer make sense, so remove those entirely.
Update the .g/s_frame_interval() callbacks to calculate the frame
interval based on the current mode and the vblank and hblank settings.

The implementation of the .enum_frame_interval() callback is no longer
suitable since the possible frame rate is now a continuous range depending
on the vblank control setting, so remove that callback entirely.

__v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which

The device is not resumed thus the remote I/O error.

Setting the frame interval works at streaming time, because
pm_runtime_resume_and_get is called at s_stream time before sensor setup.
The failure happens when only the s_frame_interval is called separately
independently on streaming time.

d64a7709a8 media: TDA1997x: replace video detection routine
The TDA1997x (HDMI receiver) driver currently uses a specific video
format detection scheme. The frame (or field in interlaced mode), line
and HSync pulse durations are compared to those of known, standard video
modes. If a match is found, the mode is assumed to be detected,
otherwise -ERANGE is returned (then possibly ignored). This means that:
- another mode with similar timings will be detected incorrectly
  (e.g. 2x faster clock and lines twice as long)
- non-standard modes will not work.

This patch replaces this scheme with a direct read of geometry
registers. This way all modes recognized by the chip are supported.

In interlaced modes, the code assumes the V sync signal has the same
duration for both fields. While this may be not necessarily true,
I can't see any way to get the "other" V sync width. This is most
probably harmless.

All tests have been performed on Gateworks' Ventana GW54xx board, with
a TDA19971 chip.

439b87fceb media: video-i2c: more precise intervals between frames
MLX90640 should ideally be working without a frame skip.
In short, if a frame is skipped, then half of a frame loses correction
information, having no way to retrieve its original compensation.

This patch improves the timing in three ways:

1) Replaced schedule_timeout_interruptible() to usleep_range()
The former "only ensures that it will sleep for at least
schedule_delay (if not interrupted)", as pointed out by mchehab.
As a result, the frame rate could lag behind than the actual capability
of the hardware
(Raspberry Pi would show a few Hz slower than set value)

2) Calculation based on us, not jiffies
Jiffies usually has resolution of 100Hz, and possibly even cruder.
MLX90640 can go up to 64Hz frame rate, which does not make sense to
calculate the interval with aforementioned resolution.

3) Interval calculation based on the last frame's end time
Using the start time of the current frame will probably make tiny bit
of drift every time. This made more sense when I didn't realize 1),
but it still makes sense without adding virtually any complexity,
so this stays in.

The 7th argument is buffer[0], which is set in the earlier call to

read, buffer[0] is not set and 0 is returned and stored in len.

The later call to hdmi_infoframe_unpack()'s size parameter is the
static size of buffer, always 40, so a short read is not caught
in hdmi_infoframe_unpacks()'s checking.  The variable len should be
used instead.

f809665ee7 media: imx258: Limit the max analogue gain to 480
The range for analog gain mentioned in the datasheet is [0, 480].
The real gain formula mentioned in the datasheet is:

	Gain = 512 / (512 – X)

Hence, values larger than 511 clearly makes no sense. The gain
register field is also documented to be of 9-bits in the datasheet.

Certainly, it is enough to infer that, the kernel driver currently
advertises an arbitrary analog gain max. Fix it by rectifying the
value as per the data sheet i.e. 480.

51f93add36 media: imx258: Rectify mismatch of VTS value
The frame_length_lines (0x0340) registers are hard-coded as follows:

- 4208x3118
  frame_length_lines = 0x0c50

- 2104x1560
  frame_length_lines = 0x0638

- 1048x780
  frame_length_lines = 0x034c

The driver exposes the V4L2_CID_VBLANK control in read-only mode and
sets its value to vts_def - height, where vts_def is a mode-dependent
value coming from the supported_modes array. It is set using one of
the following macros defined in the driver:

  #define IMX258_VTS_30FPS                0x0c98
  #define IMX258_VTS_30FPS_2K             0x0638
  #define IMX258_VTS_30FPS_VGA            0x034c

There's a clear mismatch in the value for the full resolution mode i.e.
IMX258_VTS_30FPS. Fix it by rectifying the macro with the value set for
the frame_length_lines register as stated above.

1536fbdbcb media: ov5640: Complement yuv mbus formats with their 1X16 versions
According to media bus pixel codes definition, data formats on serial
busses should be described with one bus sample per pixel.

Documentation/userspace-api/media/v4l/subdev-formats.rst states:

"The media bus pixel codes document parallel formats. Should the pixel
data be transported over a serial bus, the media bus pixel code that
describes a parallel format that transfers a sample on a single clock
cycle is used. For instance, both MEDIA_BUS_FMT_BGR888_1X24 and
MEDIA_BUS_FMT_BGR888_3X8 are used on parallel busses for transferring an
8 bits per sample BGR data, whereas on serial busses the data in this
format is only referred to using MEDIA_BUS_FMT_BGR888_1X24. This is
because there is effectively only a single way to transport that
format on the serial busses."

Some MIPI CSI receivers strictly obey this definition and declare
support for only *1X_* formats.

Hence, complement the supported media bus formats with their 1X16 versions
(currently applicable to yuyv, uyvy) to enhance interoperability with CSI
receivers.

only wait after the chip exits from reset for 350-500 microseconds
interval, which is larger than the minimum (2048 * (1 / XVCLK)) timeout

2b821698dc media: i2c: rdacm21: Power up OV10640 before OV490
The current RDACM21 initialization routine powers up the OV10640 image
sensor after the OV490 ISP. The ISP is programmed with a firmware loaded
from an embedded serial flash that (most probably) tries to interact and
program also the image sensor connected to the ISP.

As described in commit "media: i2c: rdacm21: Fix OV10640 powerup" the
image sensor powerdown signal is kept high by an internal pull up
resistor and occasionally fails to startup correctly if the powerdown
line is not asserted explicitly. Failures in the OV10640 startup causes
the OV490 firmware to fail to boot correctly resulting in the camera
module initialization to fail consequentially.

Fix this by powering up the OV10640 image sensor before testing the
OV490 firmware boot completion, by splitting the ov10640_initialize()
function in an ov10640_power_up() one and an ov10640_check_id() one.

Also make sure the OV10640 identification procedure gives enough time to
the image sensor to resume after the programming phase performed by the
OV490 firmware by repeating the ID read procedure.

This commit fixes a sporadic start-up error triggered by a failure to
detect the OV490 firmware boot completion:

ff75332b26 media: i2c: rdacm21: Fix OV10640 powerup
The OV10640 image sensor powerdown signal is controlled by the first
line of the OV490 GPIO pad #1, but the pad #0 identifier
OV490_GPIO_OUTPUT_VALUE0 was erroneously used. As a result the image
sensor powerdown signal was never asserted but was left floating and
kept high by an internal pull-up resistor, causing sporadic failures
during the image sensor startup phase.

Fix this by using the correct GPIO pad identifier and wait the mandatory
1.5 millisecond delay after the powerup lane is asserted. The reset
delay is not characterized in the chip manual if not as "255 XVCLK +
initialization". Wait for at least 3 milliseconds to guarantee the SCCB
bus is available.

While at it also fix the reset sequence, as the reset line was released
before the powerdown one, and the line was not cycled.

This commit fixes a sporadic start-up error triggered by a failure to
read the OV10640 chip ID:
rdacm21 8-0054: OV10640 ID mismatch: (0x01)

Add a new function to the max9271 library driver that wakes up the chip
with a dummy i2c transaction and implements the correct delay of 5
milliseconds after the chip exits from low power state.

Use the newly introduced function in the rdacm20 and rdacm21 camera
drivers. The former was not respecting the required delay while the
latter was waiting for a too-short timeout.

0a7790be18 media: subdev: disallow ioctl for saa6588/davinci
The saa6588_ioctl() function expects to get called from other kernel
functions with a 'saa6588_command' pointer, but I found nothing stops it
from getting called from user space instead, which seems rather dangerous.

The same thing happens in the davinci vpbe driver with its VENC_GET_FLD
command.

As a quick fix, add a separate .command() callback pointer for this
driver and change the two callers over to that.  This change can easily
get backported to stable kernels if necessary, but since there are only
two drivers, we may want to eventually replace this with a set of more
specialized callbacks in the long run.

0d346d2a6f media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.

I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.

This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.

The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:

dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done

Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

and also configuring the data lane settings in the driver based on
system configuration.

- Fix Bayer order output in 1640x1232 binning registers
- supported data lanes
  + 3280x2464 on 2 & 4 lanes
  + 1640x1232 on 2 & 4 lanes

24786ccd9c media: i2c: ov2659: Use clk_{prepare_enable,disable_unprepare}() to set xvclk on/off
On some platform(imx6q), xvclk might not switch on in advance,
also for power save purpose, xvclk should not be always on.
so, add clk_prepare_enable(), clk_disable_unprepare() in driver
side to set xvclk on/off at proper stage.

Add following changes:
- add 'struct clk *clk;' in 'struct ov2659 {}'
- enable xvclk in ov2659_power_on()
- disable xvclk in ov2659_power_off()

ff3cc65cad media: v4l: async, fwnode: Improve module organisation
The V4L2 async framework is generally used with the V4L2 fwnode, which
also depends on the former. There are a few exceptions but they are
relatively few.

At the same time there is a vast number of systems that need videodev
module, but have no use for v4l2-async that's now part of videodev.

In order to improve, split the v4l2-async into its own module. Selecting
V4L2_FWNODE also selects V4L2_ASYNC.

This also moves the initialisation of the debufs entries for async subdevs
to loading of the v4l2-async module. The directory is named as
"v4l2-async".

8edcb5049a media: I2C: change 'RST' to "RSET" to fix multiple build errors
The use of an enum named 'RST' conflicts with a #define macro
named 'RST' in arch/mips/include/asm/mach-rc32434/rb.h.

The MIPS use of RST was there first (AFAICT), so change the
media/i2c/ uses of RST to be named 'RSET'.
'git grep -w RSET' does not report any naming conflicts with the
new name.

62c9044686 media: i2c: imx334: fix the pm runtime get logic
The PM runtime get logic is currently broken, as it checks if
ret is zero instead of checking if it is an error code,
as reported by Dan Carpenter.

While here, use the pm_runtime_resume_and_get() as added by:
commit dd8088d5a8 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
added pm_runtime_resume_and_get() in order to automatically handle
dev->power.usage_count decrement on errors. As a bonus, such function
always return zero on success.

It should also be noticed that a fail of pm_runtime_get_sync() would
potentially result in a spurious runtime_suspend(), instead of
using pm_runtime_put_noidle().

da3a1858c3 media: i2c: ccs-core: fix pm_runtime_get_sync() usage count
The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.

There is a bug at ccs_pm_get_init(): when this function returns
an error, the stream is not started, and RPM usage_count
should not be incremented. However, if the calls to
v4l2_ctrl_handler_setup() return errors, it will be kept
incremented.

At ccs_suspend() the best is to replace it by the new
pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a8 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")

While the adv7604/11/12 hardware supported EDIDs up to 4 blocks, the
driver didn't. This patch adds support for this. It also improves support
for EDIDs that do not have a Source Physical Address: in that case the
spa location is set to the first byte of the second block, and the
'physical address' is just the two bytes at that location. This is per
the suggestion in the adv76xx documentation for such EDIDs.

With the introduction of the RDACM21 camera module support in commit
a59f853b3b ("media: i2c: Add driver for RDACM21 camera module") the
symbols defined by the max9271 library were exported twice if multiple
users of the library were compiled in at the same time.

In example:
WARNING: modpost: drivers/media/i2c/rdacm21-camera_module:
'max9271_set_serial_link' exported twice. Previous export was in
drivers/media/i2c/rdacm20-camera_module.ko

Fix this by making the max9271 file a module and have the driver
using its functions select it.

caught by the compiler. Wrap those functions in macros that take a
container type instead of a size, and cast the returned pointer to the
desired type. The compiler will catch mistakes if the incorrect type is
passed to the macro, as the assignment types won't match.

ae56e038f7 media: ccs: Make (non-)use of uninitialised variables more robust
GCC with W=2 level of kernel compiler warnings warns about the use of
uninitialised variables in a few locations. While these uninitialised
variables were not used in reality, this still produced compiler warnings.

Address this by assigning the variables to NULL and checking for NULL in
places it is not expected, returning -EIO in that case. This provides
at least some sanity checking at runtime as the compiler appears unable to
do that at compile time.

11c0d8fdcc media: i2c: Add support for the OV8865 image sensor
The OV8865 is a 8 Mpx CMOS image sensor producing 3264x2448 at 30 fps.
Other modes (including some with sub-sampling) are available too.
It outputs 10-bit bayer CFA data through a MIPI CSI-2 interface with
up to 4 lanes supported.

Some register initialisation sequences are still needed for this driver,
as they cover registers for which no documentation is available.

This work is based on the first version of the driver submitted by
Kévin L'hôpital, which was adapted to mainline from the Allwinner BSP.
This version is a rewrite of the first version that matches the structure
of the OV5648 driver, with explicit PLL configuration, all the necessary
mode-specific fields, associatied registers and reduced static sequences.

It was tested with the Banana Pi Camera Board v3 and the Banana Pi M3.

2b18cbcf53 media: ov5647: Fix return value from read/write
The ov5647_read()/ov5647_write() return in case of success the number
of bytes read or written respectively. This requires callers to check
if the return value is less than zero to detect an error. Unfortunately,
in several places, callers directly return the result of a read/write
call, causing issues when the returned valued is checked to be different
from zero to detect an error.

Fix this by returning zero if i2c_master_send() and i2c_master_read()
return a positive value (the number of bytes written or read).

9490a2279f media: ccs-pll: Add support flexible OP PLL pixel clock divider
Flexible OP PLL pixel clock divider allows a higher OP pixel clock than
what the bus can transfer. This generally makes it easier to select pixel
clock dividers.

This changes how the pixel rate on the bus and minimum VT divisor are
calculated, as the pixel rate is no longer directly determined by the
OP pixel clock and the number of the lanes.

Also add a sanity check for sensors that do not support flexible OP PLL
pixel clock divider. This could have caused the PLL calculator to come up
with an invalid configuration for those devices.

The external clock frequency times the PLL multiplier may exceed the value
range of 32-bit unsigned integers. Instead perform the same calculation y
using two divisions.

The result has some potential to be different, but that's ok: this number
is used to limit the range of pre-PLL divisors to find optimal values. So
the effect of the rare case of a different result here would mean an
invalid pre-PLL divisor is tried. That will be found out a little later in
any case.

Also guard against dividing by zero if the external clock frequency is
higher than the maximum OP PLL output clock --- a rather improbable case.

If the device is powered off (for example during system suspend to ram)
the devices loses its configuration, especially the slave i2c mappings

to the driver to run the probe setup again.

Add an early resume callback that reinitializes the device and setup the

1ed36ecd14 media: i2c: imx219: Selection compliance fixes
To comply with the intended usage of the V4L2 selection target when
used to retrieve a sensor image properties, adjust the rectangles
returned by the imx219 driver.

The top/left crop coordinates of the TGT_CROP rectangle were set to
(0, 0) instead of (8, 8) which is the offset from the larger physical
pixel array rectangle. This was also a mismatch with the default values
crop rectangle value, so this is corrected. Found with v4l2-compliance.

While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
CROP_BOUNDS have the same size as the non-active pixels are not readable
using the selection API. Found with v4l2-compliance.

[reword commit message, use macros for pixel offsets]

The DT bindings documented "reset-gpios" property but the driver never
made use of it. Instead it used a GPIO called "xshutdown", with apprently
wrong polarity.

Fix this by requesting "reset" GPIO with the right polarity first, and if
that fails, then request "xshutdown" GPIO with the old polarity. This way
it works for new users as expected while if someone, somewhere, depended
on "xshutdown" GPIO, that continues to work as well.
