We use encoder->get_buf_trans() in many places, for example intel_ddi_dp_voltage_max(), and the hook was set to some old platform's function for DG2 SNPS PHY. Convert SNPS PHY to use the same translation mechanisms as everything else. Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by:

ADL-P supports stream splitter on pipe B in addition to pipe A. Update the sanity check in intel_ddi_mso_get_config() to reflect this, and remove the check in intel_ddi_mso_configure() as redundant with encoder->pipe_mask. Abstract the splitter pipe mask to a single point of truth while at it to avoid similar mistakes in the future.

Atm the EFI FB platform driver gets a runtime PM reference for the associated GFX PCI device during probing the EFI FB platform device and releases it only when the platform device gets unbound. When fbcon switches to the FB provided by the PCI device's driver (for instance i915/drmfb), the EFI FB will get only unregistered without the EFI FB platform device getting unbound, keeping the runtime PM reference acquired during the platform device probing. This reference will prevent the PCI driver from runtime suspending the device. Fix this by releasing the RPM reference from the EFI FB's destroy hook, called when the FB gets unregistered. While at it assert that pm_runtime_get_sync() didn't fail. v2: - Move pm_runtime_get_sync() before register_framebuffer() to avoid its race wrt. efifb_destroy()->pm_runtime_put(). (Daniel) - Assert that pm_runtime_get_sync() didn't fail. - Clarify commit message wrt. platform/PCI device/driver and driver removal vs. device unbinding.

dispcnlunit1_cp_xosc_clkreq clock observed to be active on TGL-H platform despite Wa_14010685332 original sequence, thus blocks entry to deeper s0ix state. The Tweaked Wa_14010685332 sequence fixes this issue, therefore use tweaked Wa_14010685332 sequence for every PCH since PCH_CNP. v2: - removed RKL from comment and simplified condition.

The SFC_DONE register lives within the corresponding VD0/VD2/VD4/VD6 forcewake domain and is not accessible if the vdbox in that domain is fused off and the forcewake is not initialized. This mistake went unnoticed because until recently we were using the wrong register offset for the SFC_DONE register; once the register offset was corrected, we started hitting errors like <4> [544.989065] i915 0000:cc:00.0: Uninitialized forcewake domain(s) 0x80 accessed at 0x1ce000 on parts with fused-off vdbox engines.

Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the Dithering BPC, with valid values of 6, 8, 10 BPC. For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid values of: 6, 8, 10, 12 BPC, and need to be programmed whether dithering is enabled or not. This patch: -corrects the bits 5-7 for PIPE MISC register for 12 BPC. -renames the bits and mask to have generic names for these bits for dithering bpc and port output bpc. v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout for pipe_bpp. (Uma Shankar) v2: Added 'display' to the subject and fixes tag.

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.

The only real platform with DISPLAY_VER == 10 is GLK. We don't need to handle CNL explicitly in intel_ddi.c. A lot of special code for CNL can be removed. There were some __cnl.*() functions that were created to share the implementation between ICL and CNL. Those are now embedded in the only caller, in ICL.

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:
