2022-04-05drm/panel: Add panel driver for NewVision NV3052C based LCDsChristophe Branchereau3-0/+494
This driver supports the NewVision NV3052C based LCDs. Right now, it only supports the LeadTek LTK035C5444T 2.4" 640x480 TFT LCD panel, which can be found in the Anbernic RG-350M handheld console.

ingenic_drm_bridge_atomic_enable allows the CRTC to be enabled after panels have slept out, and before their display is turned on, solving a graphical bug on the newvision nv3502c. Also add ingenic_drm_bridge_atomic_disable to balance it out.

2022-04-05drm/i915/dp: Reorder intel_dp_compute_config() a bitVille Syrjälä1-13/+10
Consolidate the double pfit call, and reorder things so that intel_dp_output_format() and intel_dp_compute_link_config() are back-to-back. They are intimately related, and will need to be called twice to properly handle the "4:2:0 also" modes.

2022-04-05drm/i915/dp: Respect the sink's max TMDS clock when dealing with DP->HDMI DFPsVille Syrjälä1-5/+19
Currently we only look at the DFPs max TMDS clock limit when considering whether the mode is valid, or whether we can do deep color. The sink's max TMDS clock limit may be lower than the DFPs, so we need to account for it as well.

2022-04-05drm/i915: Track context current active timeTvrtko Ursulin10-50/+118
Track context active (on hardware) status together with the start timestamp. This will be used to provide better granularity of context runtime reporting in conjunction with already tracked pphwsp accumulated runtime. The latter is only updated on context save so does not give us visibility to any currently executing work. As part of the patch the existing runtime tracking data is moved under the new ce->stats member and updated under the seqlock. This provides the ability to atomically read out accumulated plus active runtime. v2: * Rename and make __intel_context_get_active_time unlocked. v3: * Use GRAPHICS_VER.

2022-04-04drm/nouveau/clk: Fix an incorrect NULL check on list iteratorXiaomeng Tong1-2/+4
The bug is here: if (nvkm_cstate_valid(clk, cstate, max_volt, clk->temp)) return cstate; The list iterator value 'cstate' will *always* be set and non-NULL by list_for_each_entry_from_reverse(), so it is incorrect to assume that the iterator value will be unchanged if the list is empty or no element is found (In fact, it will be a bogus pointer to an invalid structure object containing the HEAD). Also it missed a NULL check at callsite and may lead to invalid memory access after that. To fix this bug, just return 'encoder' when found, otherwise return NULL. And add the NULL check.
