Our hardware requires the pitch to be an even number when using YUV formats with the frontend. Implement a driver-specific callback for GEM dumb allocation that sets the pitch accordingly. Since only the bpp is passed (and not the format), we cannot really distinguish if this alignment is really required. Since it doesn't hurt to align the pitch anyway, always do it.

2018-11-27drm/sun4i: frontend: Apply format sub-sampling to CH1 dimensionsPaul Kocialkowski1-8/+16
The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate.

2018-11-27drm/sun4i: backend: Avoid counting YUV planes that use the frontendPaul Kocialkowski1-5/+5
Our hardware has a limited number of YUV planes (usually 1) that can be supported using the backend only.

2018-11-27drm/sun4i: backend: Use a specific function to check if a plane is supportedPaul Kocialkowski1-5/+22
Before this patch, it is assumed that a plane is supported either through the frontend or through the backend alone. However, the DRM interface does not allow finely reporting our hardware capabilities and there are cases where neither are support. In particular, some plane formats are supported by the backend and not the frontend, so they can only be supported without scaling.

2018-11-27drm/sun4i: backend: Refine the logic behind using the frontendPaul Kocialkowski1-2/+18
Checking that scaling is in use is not sufficient as a condition to decide to use the frontend. Since not all layer formats are supported by the frontend, we need to check for that support first.

2018-11-27drm/sun4i: frontend: Replace ARGB with XRGB as supported formatPaul Kocialkowski2-4/+3
The frontend documentation (for the A33) mentions that ARGB is supported as output, but with the alpha component always set to 0xff. In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well. The A31 and A80 SoCs apparently have a bit to enable proper alpha, but this is not supported at this point (see the comment already in the code).

This function is called first on layer atomic update to make sure that there are no leftover bits from previous plane configuration that were not cleaned until now. It fixes issues when alternating between video and YUV planes, where both bits would be set eventually, leading to broken plane display.

2018-11-23drm/atomic-helper: Complete fake_commit->flip_done potentially earlierVille Syrjälä1-0/+3
Consider the following scenario: 1. nonblocking enable crtc 2. wait for the event 3. nonblocking disable crtc On i915 this can lead to a spurious -EBUSY from step 3 on account of non-enabled planes getting the fake_commit in step 1 and we don't complete the fake_commit-> flip_done until drm_atomic_helper_commit_hw_done() which can happen a long time after the flip event was sent out. This will become somewhat easy to hit on SKL+ once we start to add all the planes for the crtc to every modeset commit for the purposes of forcing a watermark register programming [1]. To make the race a little less pronounced let's complete fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done(). For the single crtc case this should make the race quite theoretical, assuming drm_atomic_helper_wait_for_flip_done() actually has to wait for the real commit flip_done. In case the real commit flip_done gets completed singificantly before drm_atomic_helper_wait_for_flip_done(), or we are dealing with multiple crtcs whose vblanks don't line up nicely the race still exists.
