CNL A stepping was the only affected there.

Let's introduce the WA number that is the
cause of having NV12 disabled on both SLK and BXT.
According to Spec:
WA 0870: "Display flickers with NV12 video playback in
Y tiling mode.
WA: Use YUV422 surface format instead of NV12."
v2: remove the useless dead code and consequently
avoiding device info flag. (Ville)

First of all I believe this WA as written here was wrong.
Because it is listed on BSpec only for SKL and BXT, exactly
the only 2 platforms skipped here.
But also it is written there that we don't need this WA
anymore:
"This workaround is no longer needed since NV12 support is
dropped for the affected projects in #0870."
SO, let's kill it.

These registers specify the big joiner, splitter,
overlap pixels and info regarding
compression enabled on left or right branch.

- Rename the register to ICL_DSS_CTL1/2_PIPE_ (manasi)
- take pixels as an argument for overlap.(Manasi)
v3:

to avoid confusion (madhav chauhan)
- Rename registers in accordance to BSpec (Madhav, Rodrigo)
- Add define to conditionally check the buffer target depth (James Ausmus)

In case of Legacy DP connector on TypeC port, the
flex IO DPMLE register is set to number of lanes configured
by the display driver which will be programmed into DDI_BUF_CTL
PORT_WIDTH_SELECTION.
This needs to be programmed before enabling the shared PLLs hence
add a pre_pll_enable hook for ICL and add this programming in that hook.

Use intel_panel_actually_set_backlight() instead of a direct
call to pwm_config() in pwm_disable_backlight().
The main benefit is consistent debug logging when we turn off the
backlight. Currently we see nothing in dmesg which made me wonder
whether the backlight was even getting turned off properly.
The second benefit is consistency; This is what we do for all
the other backlight implementations.

When DSC is supported we need to validate the modes based on the

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)

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)

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)

Program the timeout values (in escape clock) for HS TX, LP RX and TA
timeout.
HX TX: Ensure that host does not continuously transmit in the HS
state. If this timer expires, then host will gracefully end its HS
transmission and allow the link to enter into LP state.
LP RX: Monitor the length of LP receptions from Peripheral. If timeout
happens then host will drive the stop state onto all data lanes (only
Data Lane 0 should be receiving anything from the Peripheral). This
effectively takes back ownership of the bus transmit in the HS state.
TA timeout: Timeout valuefor monitoring Bus Turn-Around (BTA) sequence.
BTA sequence should complete within a bounded amount of time, with
peripheral acknowledging BTA by driving the stop state.
v2 by Jani:
- Rebase
- Use intel_dsi_bitrate() and intel_dsi_tlpx_ns(intel_dsi)
- Squash HX TX, LP RX and TA timeout into one patch
- Fix bspec mode set sequence reference

Driver needs payload/header credits for sending any command
and data over DSI link. These credits are released once command
or data sent to link. This patch adds functions to wait for releasing
of payload and header credits.
As per BSPEC, driver needs to ensure that all of commands/data
has been dispatched to panel before the transcoder is enabled.
This patch implement those steps i.e. sending NOP DCS command,
wait for header/payload credit to be released etc.

required, the resume function can also do the simple task of notifier
the ACPI bios that we are back. This avoid some nasty restrictions on

early phase of resume.
