2022-08-29drm/i915: move wm to display.wmJani Nikula
Move display watermark related members under drm_i915_private display sub-struct. It's a bit arbitrary when to define a named struct for grouping, but clearly intel_wm is big enough to warrant a separate definition.

2022-08-28drm/msm: Fix cx collapse issue during recoveryAkhil P Oommen
There are some hardware logic under CX domain. For a successful recovery, we should ensure cx headswitch collapses to ensure all the stale states are cleard out. This is especially true to for a6xx family where we can GMU co-processor. Currently, cx doesn't collapse due to a devlink between gpu and its smmu. So the *struct gpu device* needs to be runtime suspended to ensure that the iommu driver removes its vote on cx gdsc.

2022-08-26drm/i915/dg2: Incorporate Wa_16014892111 into DRAW_WATERMARK tuningMatt Roper
Although register tuning settings are generally implemented via the workaround infrastructure, it turns out that the DRAW_WATERMARK register is not properly saved/restored by hardware around power events (i.e., RC6 entry) so updates to the value cannot be applied in the usual manner. New workaround Wa_16014892111 informs us that any tuning updates to this register must instead be applied via an INDIRECT_CTX batch buffer. This will ensure that the necessary value is re-applied when a context begins running, even if an RC6 entry had wiped the register back to hardware defaults since the last context ran.

The ICN6211 is capable of deriving its internal PLL clock from either MIPI DSI HS clock, external REFCLK clock, or even internal oscillator. Currently supported is only the first option. Add support for external REFCLK clock input in addition to that. There is little difference between these options, except that in case of MIPI DSI HS clock input, the HS clock are pre-divided by a fixed /4 divider before being fed to the PLL input, while in case of external REFCLK, the RECLK clock are fed directly into the PLL input. Per exceptionally poor documentation, the REFCLK must be in range of 10..154 MHz.

2022-08-26drm: bridge: icn6211: Add and use hs_rate and lp_rateMarek Vasut
Fill in hs_rate and lp_rate to struct mipi_dsi_device for this bridge and adjust DSI input frequency calculations such that they expect the DSI host to configure HS clock according to hs_rate. This is an optimization for the DSI burst mode case. In case the DSI device supports DSI burst mode, it is recommended to operate the DSI interface at the highest possible HS clock frequency which the DSI device supports. This permits the DSI host to send as short as possible bursts of data on the DSI link and keep the DSI data lanes in LP mode otherwise, which reduces power consumption.

2022-08-26drm: fix drm_mipi_dbi build errorsRandy Dunlap
drm_mipi_dbi needs lots of DRM_KMS_HELPER support, so select that Kconfig symbol like it is done is most other uses, and the way that it was before MIPS_DBI was moved from tinydrm to its core location.

Use 'select' instead of 'depends on' for DRM helpers for the Ilitek ILI9341 panel driver.

2022-08-26drm/i915: Skip wm/ddb readout for disabled pipesVille Syrjälä
The stuff programmed into the wm/ddb registers of planes on disabled pipes doesn't matter. So during readout just leave our software state tracking for those zeroed. This should avoid us trying too hard to clean up after whatever mess the VBIOS/GOP left in there. The actual hardware state will get cleaned up if/when we enable the pipe anyway.
