2022-03-04drm/i915: Remove framestart_delay sanitationVille Syrjälä1-56/+0
Now that we track framestart_delay in the crtc state with readout and state checker support we can remove the explicit framestart_delay sanitation code. Also I'm not convinced reprogramming this while the pipe is running is even valid. CHICKEN_TRANS (hsw+) and TRANS_CHICKEN2 (cpt+) docs at least make no mention of double buffering which seems to imply that live reprogramming is not supported. On older platforms PIPECONF and PCH_TRANSCONF (ibx) are double buffered though, so might be that we could do this on the older platforms. But doesn't really make sense to special case old platforms for this. So from now on if the BIOS has misprogrammed this we shall simply do a full modeset at boot to fix it up. Such systems will of course lose fastboot, but I think less code (and less uncertainty what reprogramming this on a running pipe will even do) outweighs that.

2022-03-04drm/i915/xehp: Support platforms with CCS engines but no RCSMatt Roper7-4/+13
In the past we've always assumed that an RCS engine is present on every platform. However now that we have compute engines there may be platforms that have CCS engines but no RCS, or platforms that are designed to have both, but have the RCS engine fused off. Various engine-centric initialization that only needs to be done a single time for the group of RCS+CCS engines can't rely on being setup with the RCS now; instead we add a I915_ENGINE_FIRST_RENDER_COMPUTE flag that will be assigned to a single engine in the group; whichever engine has this flag will be responsible for some of the general setup (RCU_MODE programming, initialization of certain workarounds, etc.).

2022-03-04drm/exynos: fimd: add BGR support for exynos4/5Martin Jücker1-2/+40
In the downstream kernels for exynos4 and exynos5 devices, there is an undocumented register that controls the order of the RGB output. It can be set to either normal order or reversed, which enables BGR support for those SoCs. This patch enables the BGR support for all the SoCs that were found to have at least one device with this logic in the corresponding downstream kernels.

2022-03-04drm/exynos: Search for TE-gpio in DSI panel's nodeMarek Szyprowski1-1/+1
TE-gpio, if defined, is placed in the panel's node, not the parent DSI node. Change the devm_gpiod_get_optional() to gpiod_get_optional() and pass proper device node to it. The code already has a proper cleanup path, so it looks that the devm_* variant has been applied accidentally during the conversion to gpiod API.

2022-03-04drm/exynos: Don't fail if no TE-gpio is defined for DSI driverMarek Szyprowski1-1/+3
TE-gpio is optional and if it is not found then gpiod_get_optional() returns NULL. In such case the code will continue and try to convert NULL gpiod to irq what in turn fails. The failure is then propagated and driver is not registered. Fix this by returning early from exynos_dsi_register_te_irq() if no TE-gpio is found.
