a9d37e6844 drm/rockchip: dw_hdmi: rename vpll clock to reference clock
"vpll" is a misnomer. A clock input to a device should be named after
the usage in the device, not after the clock that drives it. On the
rk3568 the same clock is driven by the HPLL.
To fix that, this patch renames the vpll clock to ref clock. The clock
name "vpll" is left for compatibility to old device trees.

cf544c6a88 drm/rockchip: Add crtc_endpoint_id to rockchip_encoder
The VOP2 has an interface mux which decides to which encoder(s) a CRTC
is routed to. The encoders and CRTCs are connected via of_graphs in the
device tree. When given an encoder the VOP2 driver needs to know to
which internal register setting this encoder matches. For this the VOP2
binding offers different endpoints, one for each possible encoder. The
endpoint ids of these endpoints are used as a key from an encoders
device tree description to the internal register setting.

This patch adds the key aka endpoint id to struct rockchip_encoder plus
a function to read the endpoint id starting from the encoders device
node.

540b8f271e drm/rockchip: Embed drm_encoder into rockchip_decoder
The VOP2 driver needs rockchip specific information for a drm_encoder.

This patch creates a struct rockchip_encoder with a struct drm_encoder
embedded in it. This is used throughout the rockchip driver instead of
struct drm_encoder directly.

The information the VOP2 drivers needs is the of_graph endpoint node
of the encoder. To ease bisectability this is added here.

While at it convert the different encoder-to-driverdata macros to
static inline functions in order to gain type safety and readability.

3fa50896c3 drm/rockchip: Support YUV formats with U/V swapped
The VOP in Rockchip SoCs that support YUV planes also support swapping
of the U and V elements. Supporting the swapped variants, especially
NV21, would be beneficial for multimedia applications, as the hardware
video decoders only output NV21, and supporting this pixel format in
the display pipeline would allow the decoded video frames to be output
directly.

Add support for this to support the various formats that have U/V
swapped.

d2eabdb644 drm/rockchip: rk3066_hdmi: Replace drm_detect_hdmi_monitor() with is_hdmi
Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information and stores its own cached value, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead and also remove hdmi_data_info.sink_is_hdmi as it is no longer
necessary.

421be3ee36 drm/rockchip: Refactor IOMMU initialisation
Defer the IOMMU domain setup until after successfully binding
components, so we can figure out IOMMU support directly from the VOP
devices themselves, rather than manually inferring it from the DT (which
also fails to account for whether the IOMMU driver is actually loaded).
Although this is somewhat of a logical cleanup, the main motivation is
to prepare for a change in the iommu_domain_alloc() interface.

1e0f66420b drm/display: Introduce a DRM display-helper module
Replace the DP-helper module with a display-helper module. The
support for DisplayPort becomes an internal option that drivers
have to select. Update all related Kconfig and Makefile rules.

Besides the existing code for DisplayPort, the new module will
contain helpers for other video-output standards, such as HDMI.
Drivers will have to select their required video-output helpers.

Linking all display-related code into a single module avoids the
proliferation of small kernel modules.

The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,
and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace
to drm_display_helper.

v2:
	* mention module parameters in commit message (Javier)
	* distiguish between display module and DP support in Kconfig
	* update Makefile rules for DP helpers
	* move Kconfig rules into separate file under display/

266d17a8c0 Driver core changes for 5.18-rc1
Here is the set of driver core changes for 5.18-rc1.
 
 Not much here, primarily it was a bunch of cleanups and small updates:
 	- kobj_type cleanups for default_groups
 	- documentation updates
 	- firmware loader minor changes
 	- component common helper added and take advantage of it in many
 	  drivers (the largest part of this pull request).
 
 There will be a merge conflict in drivers/power/supply/ab8500_chargalg.c
 with your tree, the merge conflict should be easy (take all the
 changes).
 
 All of these have been in linux-next for a while with no reported
 problems.

9da1e9ab82 drm/rockchip: vop: Correct RK3399 VOP register fields
Commit 7707f7227f09 ("drm/rockchip: Add support for afbc") switched up
the rk3399_vop_big[] register windows, but it did so incorrectly.

The biggest problem is in rk3288_win23_data[] vs.
rk3368_win23_data[] .format field:

  RK3288's format: VOP_REG(RK3288_WIN2_CTRL0, 0x7, 1)
  RK3368's format: VOP_REG(RK3368_WIN2_CTRL0, 0x3, 5)

Bits 5:6 (i.e., shift 5, mask 0x3) are correct for RK3399, according to
the TRM.

There are a few other small differences between the 3288 and 3368
definitions that were swapped in commit 7707f7227f09. I reviewed them to
the best of my ability according to the RK3399 TRM and fixed them up.

This fixes IOMMU issues (and display errors) when testing with BG24
color formats.

7938f42181 dma-buf-map: Rename to iosys-map
Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.

The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.

The conversion was mostly done with the following semantic patch:

	@r1@
	@@
	- struct dma_buf_map
	+ struct iosys_map

	@r2@
	@@
	(
	- DMA_BUF_MAP_INIT_VADDR
	+ IOSYS_MAP_INIT_VADDR
	|
	- dma_buf_map_set_vaddr
	+ iosys_map_set_vaddr
	|
	- dma_buf_map_set_vaddr_iomem
	+ iosys_map_set_vaddr_iomem
	|
	- dma_buf_map_is_equal
	+ iosys_map_is_equal
	|
	- dma_buf_map_is_null
	+ iosys_map_is_null
	|
	- dma_buf_map_is_set
	+ iosys_map_is_set
	|
	- dma_buf_map_clear
	+ iosys_map_clear
	|
	- dma_buf_map_memcpy_to
	+ iosys_map_memcpy_to
	|
	- dma_buf_map_incr
	+ iosys_map_incr
	)

	@@
	@@
	- #include <linux/dma-buf-map.h>
	+ #include <linux/iosys-map.h>

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.

Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.

v2:
  - Squash patches

v3:
  - Fix wrong removal of dma-buf.h from MAINTAINERS
  - Move documentation from dma-buf.rst to device-io.rst

v4:
  - Change documentation title and level

According to disable Documentation/admin-guide/kernel-parameters.txt, this
parameter can be used to disable kernel modesetting.

DRM drivers will not perform display-mode changes or accelerated rendering
and only the system framebuffer will be available if it was set-up.

But only a few DRM drivers currently check for nomodeset, make this driver

adb9d5a2cc drm/dp: Move DisplayPort helpers into separate helper module
Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c

This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:

Before:
	drm_kms_helper.ko:	447480 bytes

After:
	drm_dp_helper.ko:	216632 bytes
	drm_kms_helper.ko:	239424 bytes

For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.

e584cdc154 drm/rockchip: dsi: Reconfigure hardware on resume()
Since commit 43c2de1002d2 ("drm/rockchip: dsi: move all lane config except
LCDC mux to bind()"), we perform most HW configuration in the bind()
function. This configuration may be lost on suspend/resume, so we
need to call it again. That may lead to errors like this after system
suspend/resume:

  dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO
  panel-kingdisplay-kd097d04 ff960000.mipi.0: failed write init cmds: -110

Tested on Acer Chromebook Tab 10 (RK3399 Gru-Scarlet).

Note that early mailing list versions of this driver borrowed Rockchip's
downstream/BSP solution, to do HW configuration in mode_set() (which
*is* called at the appropriate pre-enable() times), but that was
discarded along the way. I've avoided that still, because mode_set()
documentation doesn't suggest this kind of purpose as far as I can tell.

514db87192 drm/rockchip: dsi: Hold pm-runtime across bind/unbind
In commit 43c2de1002d2 ("drm/rockchip: dsi: move all lane config except
LCDC mux to bind()"), we moved most HW configuration to bind(), but we
didn't move the runtime PM management. Therefore, depending on initial
boot state, runtime-PM workqueue delays, and other timing factors, we
may disable our power domain in between the hardware configuration
(bind()) and when we enable the display. This can cause us to lose
hardware state and fail to configure our display. For example:

  dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO
  panel-innolux-p079zca ff960000.mipi.0: failed to write command 0

or:

  dw-mipi-dsi-rockchip ff968000.mipi: failed to write command FIFO
  panel-kingdisplay-kd097d04 ff960000.mipi.0: failed write init cmds: -110

We should match the runtime PM to the lifetime of the bind()/unbind()
cycle.

Tested on Acer Chrometab 10 (RK3399 Gru-Scarlet), with panel drivers
built either as modules or built-in.

Side notes: it seems one is more likely to see this problem when the
panel driver is built into the kernel. I've also seen this problem
bisect down to commits that simply changed Kconfig dependencies, because
it changed the order in which driver init functions were compiled into
the kernel, and therefore the ordering and timing of built-in device
probe.

64ec4912c5 drm/rockchip: Update crtc fixup to account for fractional clk change
After commit 928f9e268611 ("clk: fractional-divider: Hide
clk_fractional_divider_ops from wide audience") was merged it appears
that the DSI panel on my Odroid Go Advance stopped working. Upon closer
examination of the problem, it looks like it was the fixup in the
rockchip_drm_vop.c file was causing the issue. The changes made to the
clk driver appear to change some assumptions made in the fixup.

After debugging the working 5.14 kernel and the no-longer working
5.15 kernel, it looks like this was broken all along but still
worked, whereas after the fractional clock change it stopped
working despite the issue (it went from sort-of broken to very broken).

In the 5.14 kernel the dclk_vopb_frac was being requested to be set to
17000999 on my board. The clock driver was taking the value of the
parent clock and attempting to divide the requested value from it
(17000000/17000999 = 0), then subtracting 1 from it (making it -1),
and running it through fls_long to get 64. It would then subtract
the value of fd->mwidth from it to get 48, and then bit shift
17000999 to the left by 48, coming up with a very large number of
7649082492112076800. This resulted in a numerator of 65535 and a
denominator of 1 from the clk driver. The driver seemingly would
try again and get a correct 1:1 value later, and then move on.

Output from my 5.14 kernel (with some printfs for good measure):
[    2.830066] rockchip-drm display-subsystem: bound ff460000.vop (ops vop_component_ops)
[    2.839431] rockchip-drm display-subsystem: bound ff450000.dsi (ops dw_mipi_dsi_rockchip_ops)

[    2.903529] Clock is dclk_vopb_frac

Contrast this with 5.15 after the clk change where the rate of 17000999
was getting passed and resulted in numerators/denomiators of 17001/
17000.

Output from my 5.15 kernel (with some printfs added for good measure):
[    2.817571] rockchip-drm display-subsystem: bound ff460000.vop (ops vop_component_ops)
[    2.826975] rockchip-drm display-subsystem: bound ff450000.dsi (ops dw_mipi_dsi_rockchip_ops)

[    2.891281] Rate 17001000, Parent Rate 17000000, Best Numerator 17001, Best Denominator 17000

I have tested the change extensively on my Odroid Go Advance (Rockchip
RK3326) and it appears to work well. However, this change will affect
all Rockchip SoCs that use this driver so I believe further testing
is warranted. Please note that without this change I can confirm
at least all PX30s with DSI panels will stop working with the 5.15
kernel.

Upon advice from Doug Anderson <dianders@chromium.org> it was decided
that we would first check if the clock rate can be set exactly as
requested, and only if it could not would we then add 999 to it and
attempt the process again. This way we can preserve the behavior for
clocks that still need it while resolving the specific issue for the
PX30 and DSI panels (since it is using a fractional clock).

Changes since v2:
 - Moved fixes to correct location.

Changes since v1:
 - Made the addition of 999 conditional based on whether the clock
   subsystem can set the actual clock rate as requested.
 - Updated the notes in the fixup routine to reflect this new behavior.
 - Added reference to original commit, as this has technically been
   broken since then however only now is it an issue due to the clock
   changes.

2e87bf389e drm/rockchip: add DRM_BRIDGE_ATTACH_NO_CONNECTOR flag to drm_bridge_attach
Commit a25b988ff83f ("drm/bridge: Extend bridge API to disable connector creation")
added DRM_BRIDGE_ATTACH_NO_CONNECTOR bridge flag and all bridges handle
this flag in some way since then.
Newly added bridge drivers must no longer contain the connector creation and
will fail probing if this flag isn't set.

In order to be able to connect to those newly added bridges as well,
make use of drm_bridge_connector API and have the connector initialized
by the display controller.
