3250cdf938 drm: bridge/dw_hdmi: add audio sample channel status setting
When transmitting IEC60985 linear PCM audio, we configure the
Aduio Sample Channel Status information in the IEC60958 frame.
The status bit is already available in iec.status of hdmi_codec_params.

This fix the issue that audio does not come out on some monitors
(e.g. LG 22CV241)

Note that these registers are only for interfaces:
I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA
(AHBAUDDMA).
For S/PDIF interface this information comes from the stream.

Currently this function dw_hdmi_set_channel_status is only called
from dw-hdmi-i2s-audio in I2S setup.

37a48adfba drm/vram: Add kmap ref-counting to GEM VRAM objects
The kmap and kunmap operations of GEM VRAM buffers can now be called
in interleaving pairs. The first call to drm_gem_vram_kmap() maps the
buffer's memory to kernel address space and the final call to
drm_gem_vram_kunmap() unmaps the memory. Intermediate calls to these
functions increment or decrement a reference counter.

This change allows for keeping buffer memory mapped for longer and

Use the new cec_notifier_conn_(un)register() functions to
(un)register the notifier for the HDMI connector, and fill in
the cec_connector_info.

Changes since v7:
	- err_runtime_disable -> err_rpm_disable
Changes since v2:
	- removed unnecessary call to invalidate phys address before
	deregistering the notifier,
	- use cec_notifier_phys_addr_invalidate instead of setting
	invalid address on a notifier.

92a57b3fb5 drm/stm: ltdc: add pinctrl for DPI encoder mode
The implementation of functions encoder_enable and encoder_disable
make possible to control the pinctrl according to the encoder type.
The pinctrl must be activated only if the encoder type is DPI.
This helps to move the DPI-related pinctrl configuration from
all the panel or bridge to the LTDC dt node.

89958b7cd9 drm/bridge: panel: Infer connector type from panel by default
The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().

Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

@@
expression bridge;
expression dev;
expression panel;
identifier type;
@@
(
-bridge = drm_panel_bridge_add(panel, type);
+bridge = drm_panel_bridge_add_typed(panel, type);
|
-bridge = devm_drm_panel_bridge_add(dev, panel, type);
+bridge = devm_drm_panel_bridge_add_typed(dev, panel, type);

9a2654c0f6 drm/panel: Add and fill drm_panel type field
Add a type field to the drm_panel structure to report the panel type,
using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS,
eDP, DSI and DPI). This will be used to initialise the corresponding
connector type.

Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

c7581a414d drm: Use EOPNOTSUPP, not ENOTSUPP
- it's what we recommend in our docs:

https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#recommended-ioctl-return-values

- it's the overwhelmingly used error code for "operation not
  supported", at least in drm core (slightly less so in drivers):

$ git grep EOPNOTSUPP -- drivers/gpu/drm/*c | wc -l
83
$ git grep ENOTSUPP -- drivers/gpu/drm/*c | wc -l
5

- include/linux/errno.h makes it fairly clear that these are for nfsv3
  (plus they also have error codes above 512, which is the block with
  some special behaviour ...)

/* Defined for the NFSv3 protocol */

If the above isn't reflecting current practice, then I guess we should
at least update the docs.

Noralf commented:

Ben Hutchings made this comment[1] in a thread about use of ENOTSUPP in
drivers:

  glibc's strerror() returns these strings for ENOTSUPP and EOPNOTSUPP
  respectively:

  "Unknown error 524"
  "Operation not supported"

So at least for errors returned to userspace EOPNOTSUPP makes sense.

José asked:

> Hopefully this will not break any userspace

None of the functions in drm_edid.c affected by this reach userspace,
it's all driver internal.

Same for the mipi function, that error code should be handled by
drivers. Drivers are supposed to remap "the hw is on fire" to EIO when
reporting up to userspace, but I think if a driver sees this it would
be a driver bug.
v2: Augment commit message with comments from Noralf and José

Move object release into a separate worker.  Releasing objects requires
sending commands to the host.  Doing that in the dequeue worker will
cause deadlocks in case the command queue gets filled up, because the
dequeue worker is also the one which will free up slots in the command
queue.
