2023-10-16drm/mediatek: De-commonize disp_aal/disp_gamma gamma_set functionsAngeloGioacchino Del Regno
In preparation for adding a 12-bits gamma support for the DISP_GAMMA IP, remove the mtk_gamma_set_common() function and move the relevant bits in mtk_gamma_set() for DISP_GAMMA and mtk_aal_gamma_set() for DISP_AAL: since the latter has no more support for gamma manipulation (being moved to a different IP) in newer revisions, those functions are about to diverge and it makes no sense to keep a common one (with all the complications of passing common data and making exclusions for device driver data) for just a few bits. This commit brings no functional changes. Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Nícolas F. R. A.

2023-10-16drm/mediatek: gamma: Enable the Gamma LUT table only after programmingAngeloGioacchino Del Regno
Move the write to DISP_GAMMA_CFG to enable the Gamma LUT to after programming the actual table to avoid potential visual glitches during table modification. Note: GAMMA should get enabled in between vblanks, but this requires many efforts in order to make this happen, as that requires migrating all of the writes to make use of CMDQ instead of cpu writes and that's not trivial. For this reason, this patch only moves the LUT enable. The CMDQ rework will come at a later time.

2023-10-16drm/msm/dsi: free TX buffer in unbindDmitry Baryshkov
If the drm/msm init code gets an error during output modeset initialisation, the kernel will report an error regarding DRM memory manager not being clean during shutdown. This is because msm_dsi_modeset_init() allocates a piece of GEM memory for the TX buffer, but destruction of the buffer happens only at msm_dsi_host_destroy(), which is called during DSI driver's remove() time, much later than the DRM MM shutdown. To solve this issue, move the TX buffer destruction to dsi_unbind(), so that the buffer is destructed at the correct time. Note, we also have to store a reference to the address space, because priv->kms->aspace is cleared before components are unbound.

2023-10-16drm/i915/dp: Store DSC DPCD capabilities in the connectorImre Deak
In an MST topology the DSC capabilities are specific to each connector, retrieved either from the sink if it decompresses the stream, or from a branch device between the source and the sink in case this branch device does the decompression. Accordingly each connector needs to cache its own DSC DPCD and FEC capabilities, along with the AUX device through which the decompression can be enabled. This patch prepares for that by storing the capabilities and the DSC AUX device in the connector, for now these just matching the version stored in intel_dp. The follow-up patches will convert all users to look up these in the connector instead of intel_dp, after which the intel_dp copies are removed. v2: - Rebased on intel_edp_get_dsc_sink_cap() addition in previous patch. v3: - Rebased on read-out fix for eDP in previous patch.

2023-10-16drm: renesas: shmobile: Turn vblank on/off when enabling/disabling CRTCGeert Uytterhoeven
The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_{on,off}() helpers. Note that drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. This is performed at CRTC creation time, requiring vertical blank initialization to be moved before creating CRTCs.

Turning a CRTC off will prevent a queued page flip from ever completing, potentially confusing userspace. Wait for queued page flips to complete before turning the CRTC off to avoid this.
