956aee8fa3 drm/i915/rkl: new rkl ddc map for different PCH 
After boot into kernel. Driver configured ddc pin mapping based on
predefined table in parse_ddi_port(). Now driver configure rkl
ddc pin mapping depends on icp_ddc_pin_map[]. Then this table will
give incorrect gmbus port number to cause HDMI can't work.

Refer to commit cd0a89527d ("drm/i915/rkl: Add DDC pin mapping").
Create two ddc pin table for rkl TGP and CMP pch. Then HDMI can
works properly on rkl.

v2: update patch based on latest dinq branch.
v3: update ddc table for RKL+TGP sku.
    RKL+CNP sku will load cnp_ddc_pin_map[] setting.
v4: modify the if/else judgment to avoid nesting.
v5: fix typo in v4.

3fea9f4244 drm/i915/display/psr: Use plane damage clips to calculate damaged area 
Now using plane damage clips property to calcualte the damaged area.
Selective fetch only supports one region to be fetched so software
needs to calculate a bounding box around all damage clips.

Now that we are not complete fetching each plane, there is another
loop needed as all the plane areas that intersect with the pipe
damaged area needs to be fetched from memory so the complete blending
of all planes can happen.

v2:
- do not shifting new_plane_state->uapi.dst only src is in 16.16 format

v4:
- setting plane selective fetch area using the whole pipe damage area
- mark the whole plane area damaged if plane visibility or alpha
changed

v5:
- taking in consideration src.y1 in the damage coordinates
- adding to the pipe damaged area planes that were visible but are
invisible in the new state

v6:
- consider old state plane coordinates when visibility changes or it
moved to calculate damaged area
- remove from damaged area the portion not in src clip

v7:
- intersec every damage clip with src to minimize damaged area

v8:
- adjust pipe_damaged area to 4 lines grouping
- adjust calculation now that is understood that uapi.src is the
framebuffer coordinates that plane will start to fetch from

v9:
- Only add plane dst or src to damaged_area if visible
- Early skip plane damage calculation if it was not visible in old and
new state

b3304591f1 drm/i915/dp: Track pm_qos per connector 
Since multiple connectors may run intel_dp_aux_xfer conncurrently, a
single global pm_qos does not suffice. (One connector may disable the
dma-latency boost prematurely while the second is still depending on
it.) Instead of a single global pm_qos, track the pm_qos request for
each intel_dp.

v2: Move the pm_qos setup/teardown to intel_dp_aux_init/fini

separate PWM-related backlight callbacks from other means of backlight

f12110afee drm/i915/dp: Program source OUI on eDP panels 
Since we're about to start adding support for Intel's magic HDR
backlight interface over DPCD, we need to ensure we're properly
programming this field so that Intel specific sink services are exposed.
Otherwise, 0x300-0x3ff will just read zeroes.

We also take care not to reprogram the source OUI if it already matches
what we expect. This is just to be careful so that we don't accidentally
take the panel out of any backlight control modes we found it in.

v2:
* Add careful parameter to intel_edp_init_source_oui() to avoid
  re-writing the source OUI if it's already been set during driver
  initialization

420798a09d drm/i915/dsc: make rc_model_size an encoder defined value 
Move the initialization of the rc_model_size from the common code into
encoder code, allowing different encoders to specify the size according
to their needs. Keep using the hard coded value in the encoders for now
to make this a non-functional change.

e5b9cbd381 drm/i915/dsc: configure hardware using specified rc_model_size 
The rc_model_size is specified in the DSC config, and the hardware
programming should respect that instead of hard coding a value of 8192.

Regardless, the rc_model_size in DSC config is currently hard coded to
the same value, so this should have no impact, other than allowing the
use of other sizes as needed.

1f22ed3691 drm/dsc: use rc_model_size from DSC config for PPS 
The PPS is supposed to reflect the DSC config instead of hard coding the
rc_model_size. Make it so.

Currently all users of drm_dsc_pps_payload_pack() hard code the size to
8192 also in the DSC config, so this change should have no impact, other
than allowing the drivers to use other sizes as needed.

d371d6ea92 drm/i915/display/dp: Compute the correct slice count for VDSC on DP 
This patch fixes the slice count computation algorithm
for calculating the slice count based on Peak pixel rate
and the max slice width allowed on the DSC engines.
We need to ensure slice count > min slice count req
as per DP spec based on peak pixel rate and that it is
greater than min slice count based on the max slice width
advertised by DPCD. So use max of these two.
In the prev patch we were using min of these 2 causing it
to violate the max slice width limitation causing a blank
screen on 8K@60.
