drm/mediatek: Add mt8188 dpi compatibles and platform data

2022-11-23T15:12:29Z

For MT8188, the vdosys0 only supports 1T1P mode, so we need to add the compatible for mt8188 edp-intf. Signed-off-by: xinlei lee Link: https://patchwork.kernel.org/project/linux-mediatek/patch/1666266353-16670-3-git-send-email-xinlei.lee@mediatek.com/ Signed-off-by: Chun-Kuang Hu

These drivers include the deprecated OF GPIO header yet fail to use symbols from it, so drop the include.

drm/mediatek: dpi: Add dp_intf support

2022-07-06T14:51:44Z

Dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code. This patch adds support for mt8195-dpintf to this dpi driver. Main differences are: - 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one iteration. - Input of dp_intf is two pixels per iteration. - Some register contents differ slightly between the two components.

drm/mediatek: dpi: Add pixels_per_iter config support

2022-07-06T14:32:07Z

The quantity of output for one iteration could be different for dpi and dp_intf. For dp_intf, it's 4 pixels for one iteration it's 1 pixel for one iteration for dpi. Therefore, we add a new config "pixels_per_iter" to control quantity of transferred pixels per iteration.
