CI test results/further experiments show that the workaround added in commit 573d7ce4 ("drm/i915/adlp: Add workaround to disable CMTG clock gating") can be applied only while DPLL0 is enabled. If it's disabled the TRANS_CMTG_CHICKEN register is not accessible. Accordingly move the WA to DPLL0 HW state sanitization and enabling. This fixes an issue where the WA won't get applied (and a WARN is thrown due to an unexpected value in TRANS_CMTG_CHICKEN) if the driver is loaded without DPLL0 being enabled: booting without BIOS enabling an output with this PLL, or reloading the driver. While at it also add a debug print for the unexpected register value. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

The register offset for SFC_DONE was missing a '0' at the end, causing us to read from a non-existent register address. We only use this register in error state dumps so the mistake hasn't caused any real problems, but fixing it will hopefully make the error state dumps a bit more useful for debugging.

DG1 and XE_PLD platforms has Audio MMIO/VERBS lies in PG0 power well. Adjusting the power domain accordingly to POWER_DOMAIN_AUDIO_MMIO for audio detection and POWER_DOMAIN_AUDIO_PLAYBACK for audio playback. While doing this it requires to use POWER_DOMAIN_AUDIO_MMIO power domain instead of POWER_DOMAIN_AUDIO in crtc power domain mask and POWER_DOMAIN_AUDIO_PLAYBACK with intel_display_power_{get, put} to enable/disable display audio codec power. It will save the power in use cases when DP/HDMI connectors configured with PIPE_A without any audio playback. v1: Changes since RFC - changed power domain names. [Imre] - Removed TC{3,6}, AUX_USBC{3,6} and TBT from DG1 power well and PW_3 power domains. [Imre] - Fixed the order of powe wells , power domains and its registration. [Imre] v2: - Not allowe DC states when AUDIO_MMIO domain enabled. [Imre] v3: - Squashes the commits of series to avoid build failure.

With all the users removed, finish removing the CNL platform definitions. We will leave the PCI IDs around as those are exposed to userspace. Even if mesa doesn't support CNL anymore, let's avoid build breakages due to changing the headers. Also, due to drm/i915/gt still using IS_CANNONLAKE() let's just redefine it instead of removing.

The numbers of scalers and sprites depend on the display version, so use it instead of GRAPHICS_VER. We were mixing both, which let me confused while removing CNL and GRAPHICS_VER == 10. v2 (Rodrigo): Switch IS_GEMINILAKE to DISPLAY_VER == 10 v3 (Lucas): Change check to DISPLAY_VER >= 9, to cover the GLK's num_scalers, otherwise it remains set to 0.

Explicit support for CNL is being removed from the driver as it's not expected to work. Remove the workaround for PORT_F from display/intel_bios.c so we can also remove the generic DISPLAY_VER == 10 calls to intel_ddi_init(): the only platform with that display version is already handled separately (GLK).

Source needs to write DPCD 103-106 after receiving a PHY request to change swing/pre-emphasis after reading DPCD 206-207. This is especially needed if there is a retimer between source and sink and the retimer implements AUX_CH interception scheme to manage DP PHY settings (e.g. adjusting Swing/Pre-emphasis equalization level) for DP output channel. If the source doesn't write to DPCD 103-106, the retimer may not output the requested swing/pre-emphasis and eventually we fail compliance. v2: Rebase and use crtc->lane_count (Imre) Signed-off-by:

DG2 has some changes to the expected modesetting sequences when compared to gen12. Adjust our driver logic accordingly. Although the DP sequence is pretty similar to TGL's, there are some steps that change, so let's split the handling for that out into a separate function. v2: - Switch wait_for_us() -> _wait_for() so that we can parameterize the timeout rather than duplicating the macro call.
