Pull drm updates from Dave Airlie:
"There are two external interactions of note, the msm tree pull in some
opp tree, hopefully the opp tree arrives from the same git tree
however it normally does.
There is also a new cgroup controller for device memory, that is used

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.

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

AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

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.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

The IT6505 bridge chip has a active low reset line. Since it is a
"reset" and not an "enable" line, the GPIO should be asserted to
put it in reset and deasserted to bring it out of reset during
the power on sequence.
The polarity was inverted when the driver was first introduced, likely
because the device family that was targeted had an inverting level
shifter on the reset line.
The MT8186 Corsola devices already have the IT6505 in their device tree,
but the whole display pipeline is actually disabled and won't be enabled
until some remaining issues are sorted out. The other known user is
the MT8183 Kukui / Jacuzzi family; their device trees currently do not
have the IT6505 included.
Fix the polarity in the driver while there are no actual users.
