drm/sun4i: dw-hdmi: fix error return code in sun8i_dw_hdmi_bind()

2020-11-24T12:39:03+00:00

[ Upstream commit 6654b57866b98230a270953dd34f67de17ab1708 ] Fix to return a negative error code from the error handling case instead of 0 in function sun8i_dw_hdmi_bind().

drm/sun4i: frontend: Fix the scaler phase on A33

2020-11-10T11:39:04+00:00

[ Upstream commit e3190b5e9462067714d267c40d8c8c1d0463dda3 ] The A33 has a different phase parameter in the Allwinner BSP on the channel1 than the one currently applied. Fix this.

drm/sun4i: frontend: Reuse the ch0 phase for RGB formats

2020-11-10T11:39:04+00:00

[ Upstream commit 2db9ef9d9e6ea89a9feb5338f58d1f8f83875577 ] When using the scaler on the A10-like frontend with single-planar formats, the current code will setup the channel 0 filter (used for the R or Y component) with a different phase parameter than the channel 1 filter (used for the G/B or U/V components). This creates a bleed out that keeps repeating on of the last line of the RGB plane across the rest of the display. The Allwinner BSP either applies the same phase parameter over both channels or use a separate one, the condition being whether the input format is YUV420 or not. Since YUV420 is both subsampled and multi-planar, and since YUYV is subsampled but single-planar, we can rule out the subsampling and assume that the condition is actually whether the format is single or multi-planar. And it looks like applying the same phase parameter over both channels for single-planar formats fixes our issue, while we keep the multi-planar formats working properly.

drm/sun4i: frontend: Rework a bit the phase data

2020-11-10T11:39:04+00:00

[ Upstream commit 84c971b356379c621df595bd00c3114579dfa59f ] The scaler filter phase setup in the allwinner kernel has two different cases for setting up the scaler filter, the first one using different phase parameters for the two channels, and the second one reusing the first channel parameters on the second channel. The allwinner kernel has a third option where the horizontal phase of the second channel will be set to a different value than the vertical one (and seems like it's the same value than one used on the first channel). However, that code path seems to never be taken, so we can ignore it for now, and it's essentially what we're doing so far as well. Since we will have always the same values across each components of the filter setup for a given channel, we can simplify a bit our frontend structure by only storing the phase value we want to apply to a given channel.
