[CI 1/7] drm/i915/dsc: Add slice_row_per_frame in DSC PPS programming

[Manasi Navare]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

Add the newly added slice_row_per_frame parameter
in the Picture Parameter Set registers.
This defines the number of vertically stacked slices
in a frame.

Credits to Manasi for noticing bSpec change.

[CI 2/7] drm/dp: Add DP DSC DPCD receiver capability size define and missing SHIFT

[Manasi Navare]

This patch defines the DP DSC receiver capability size that gives
total number of DP DSC DPCD registers.
This also adds a missing #defines for DP DSC support missed in the
commit id (ab6a46ea6842ce "Add DPCD definitions for DP 1.4 DSC feature")

v3:
* MIN_SLICE_WIDTH = 2560 (Anusha)
* Define DP_DSC_SLICE_WIDTH_MULTIPLIER = 320
v2:
* Add SHIFT define and DECOMPRESSION_EN define missed in prev patch

[CI 3/7] drm/i915/dp: Cache the DP/eDP DSC DPCD register set on Hotplug/eDP Init

[Manasi Navare]

DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting
GEN 11.
This patch implements the discovery phase of DSC. On hotplug,
source reads the DSC DPCD register set (0x00060 - 0x0006F) to
read the decompression capabilities of the sink device.
This entire block of registers is cached in intel_dp so that
capability information can be used during DSC configuration
phase during compute_config phase of the modeset.
For eDP, this caching happens during the eDP initialization.
This caching is done only for eDP and DP rev >= 1.4

v5:
* Fix the block comment (Gaurav)
* Fix the commit message DSC DPCD addresses (Gaurav)
* Use DRM_ERROR for dpcd_read fail (Gaurav,Anusha)
v4:
* Cache these only for Gen >= 11
v3:
* Remove the dsc_sink_support field in intel_dp (Jani N)
v2:
* Clear the cached registers on hotplug always (Jani N)
* Combine the eDP and DP caching in same function (Jani N)

[CI 5/7] drm/i915/dp: Add helpers for Compressed BPP and Slice Count for DSC

[Manasi Navare]

This patch adds helpers for calculating the maximum compressed BPP
supported with small joiner.
This also adds a helper for calculating the slice count in case
of small joiner.
These are inside intel_dp since they take into account hardware
limitations.

v6:
* Take mode_clock and mode_hdisplay as input arguments
so that this can be called in intel_dp_mode_valid (Manasi)
v5:
* Get the max slice width from DPCD
* Check against Min_Slice_width of 2560 (Anusha)
v4:
* #defines for PPR in slice count helper (Gaurav)
v3:
* Simply logic for bpp (DK)
* Limit the valid slice count by max supported by Sink (Manasi)
v2:
* Change the small joiner RAM buffer constant as bspec changed (Manasi)
* rename it as SMALL_JOINER since we are not enabling big joiner yet (Anusha)

[CI 6/7] drm/i915/dp: Validate modes using max Output BPP and slice count when DSC supported

[Manasi Navare]

When DSC is supported we need to validate the modes based on the
maximum supported compressed BPP and maximum supported slice count.
This allows us to allow the modes with pixel clock greater than the
available link BW as long as it meets the compressed BPP
and slice count requirements.

v3:
* Use the macro for dsc sink support (Jani N)
v2:
* Properly comment why we are right shifting the bpp value (Anusha)
