041d61ad66 drm/bridge: it6505: add I2C functionality on AUX 
DisplayPort AUX protocol supports I2C transport which is capable of
reading EDID or supports MCCS.

In drm_dp_helper, drm_dp_i2c_xfer() packs I2C requests into a
sequence of AUX requests.
it6505_aux_i2c_operation() is implemented to match drm_dp_i2c_xfer()
operactions.
it6505_aux_i2c_transfer() adds I2C functionality
for it6505_aux_transfer().

aa97239300 drm/bridge: it6505: fix HDCP CTS KSV list read with UNIGRAF DPR-100. 
When running the HDCP CTS test with UNIGRAF DPR-100.
KSV list must be read from DP_AUX_HDCP_KSV_FIFO in an AUX request,
and can not separate with multiple read requests.

The AUX operation command "CMD_AUX_GET_KSV_LIST" reads the KSV list
with AUX FIFO and is able to read DP_AUX_HDCP_KSV_FIFO in an AUX request.

Add it6505_get_ksvlist() which uses CMD_AUX_GET_KSV_LIST operation
to read the KSV list.

235d9bf8a1 drm/bridge: it6505: add AUX operation for HDCP KSV list read 
HDCP KSV list readback can choose to use AUX FIFO or
general data register.
For some DisplayPort devices, the KSV list must be read
in 5 byte boundaries.
The original AUX read command does not support these devices.

The AUX command operation control register "REG_AUX_CMD_REQ" uses b[3:0]
as AUX operacion control, and b[7:4] are status bits and read only.
To change KSV read operation uses "CMD_AUX_NATIVE_READ" from using
the data registers to using AUX FIFO.
The extended command "CMD_AUX_GET_KSV_LIST" is added as
"CMD_AUX_NATIVE_READ" with the 0x10 flag which selects AUX FIFO mode.

a253b0b129 drm/bridge:anx7625: Update HDCP content status 
When user enabled HDCP feature, userspace will set HDCP content
to DRM_MODE_CONTENT_PROTECTION_DESIRED. Next, anx7625 will update
HDCP content to DRM_MODE_CONTENT_PROTECTION_ENABLED if down stream
support HDCP feature.

As anx7625 bridge IC will be power down after call .atomic_disable(),
then all HDCP status will be lost on chip. So we should reestablish
HDCP again in .atomic_enable(), and update hdcp content to DESIRE if
current HDCP content is ENABLE in .atomic_disable().

v4:
 - Change HDCP content value to DESIRED if HDCP status is ENABLE in bridge
interface .atomic_enable().

v3:
 - Move hdcp content value checking from bridge interface
.atomic_check() to .atomic_enable()

v2:
 - Add more details in commit message

74ef9527bd drm/amdgpu: track bo memory stats at runtime 
Before, every time fdinfo is queried we try to lock all the BOs in the
VM and calculate memory usage from scratch. This works okay if the
fdinfo is rarely read and the VMs don't have a ton of BOs. If either of
these conditions is not true, we get a massive performance hit.

In this new revision, we track the BOs as they change states. This way
when the fdinfo is queried we only need to take the status lock and copy
out the usage stats with minimal impact to the runtime performance. With
this new approach however, we would no longer be able to track active
buffers.

amdgpu_vm_bo_invalidate doesn't use the adev parameter and not all
callers have a reference to adev handy, so remove it for cleanliness.

e77d0401e8 Documentation/gpu: Clarify drm memory stats definition 
Define how to handle buffers with multiple possible placement so we
don't get incompatible implementations. Callout the resident requirement
for drm-purgeable- explicitly. Remove the requirement for there to be
only drm-memory- or only drm-resident-, it's not what's implemented and
having both is better for back-compat. Also re-order the paragraphs to
flow better.

bebf2ebd70 drm: make drm-active- stats optional 
When memory stats is generated fresh everytime by going though all the
BOs, their active information is quite easy to get. But if the stats are
tracked with BO's state this becomes harder since the job scheduling
part doesn't really deal with individual buffers.

Make drm-active- optional to enable amdgpu to switch to the second
method.

documents problems of drm_sched_fini() in form of a list. The checklist
triggers htmldocs warning (but renders correctly in htmldocs output):

Documentation/gpu/drm-mm:571: ./drivers/gpu/drm/scheduler/sched_main.c:1359: ERROR: Unexpected indentation.

Separate the list from the preceding paragraph by a blank line to fix
the warning. While at it, also end the aforementioned paragraph by a

d2b8c6d549 drm/bridge: ti-sn65dsi83: Add ti,lvds-vod-swing optional properties 
Add a optional properties to change LVDS output voltage. This should not
be static as this depends mainly on the connected display voltage
requirement. We have three properties:
- "ti,lvds-termination-ohms", which sets near end termination,
- "ti,lvds-vod-swing-data-microvolt" and
- "ti,lvds-vod-swing-clock-microvolt" which both set LVDS differential
output voltage for data and clock lanes. They are defined as an array
with min and max values. The appropriate bitfield will be set if
selected constraints can be met.

If "ti,lvds-termination-ohms" is not defined the default of 200 Ohm near
end termination will be used. Selecting only one:
"ti,lvds-vod-swing-data-microvolt" or
"ti,lvds-vod-swing-clock-microvolt" can be done, but the output voltage
constraint for only data/clock lanes will be met. Setting both is
recommended.

3ec5c15793 drm: xlnx: zynqmp_dpsub: Add DP audio support 
Add basic DisplayPort audio support.

Support non-live audio playback from two PCMs (DMA channels), and the
volume control in the audio mixer.

As older dtb files may not have the audio DMA channels defined, the
driver will just mark the audio support as disabled if the audio DMA is
missing, and will continue with only display support.

Note: Reset doesn't seem to work (ZYNQMP_DISP_AUD_SOFT_RESET). If we do
a reset, audio playback won't start again even if, afaics, we do set up
all the necessary registers. So, at the moment, resetting the audio
block in dp_dai_hw_free() is commented out.

9367ab5d7f dt-bindings: display/xlnx/zynqmp-dpsub: Add audio DMAs 
The DP subsystem for ZynqMP supports audio via two channels, and the DP
DMA has dma-engines for those channels. For some reason the DT binding
has not specified those channels, even if the picture included in
xlnx,zynqmp-dpsub.yaml shows "2 x aud" DMAs.

This hasn't caused any issues as the drivers have not supported audio,
and has thus gone unnoticed.

To make it possible to add the audio support to the driver, add the two
audio DMAs to the binding. While strictly speaking this is an ABI break,
there should be no regressions caused by this as we're adding new
entries at the end of the dmas list, and, after the audio support has
been added in "arm64: dts: zynqmp: Add DMA for DP audio",  the driver
will treat the audio DMAs as optional to also support the old bindings.
