Mediatek DRM Next for Linux 5.20

1. Add Mediatek Soc DRM (vdosys0) support for mt8195
2. Cooperate with DSI RX devices to modify dsi funcs and delay mipi high to cooperate with panel sequence
3. Add mt8186 dsi compatible and convert dsi_dtbinding to .yaml
4. Add MediaTek SoC DRM (vdosys1) support for mt8195
5. Add MT8195 dp_intf driver

drm/mediatek: dpi: Add dp_intf support

2022-07-06T14:51:44+00:00

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

2022-07-06T14:32:07+00:00

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.

drm/mediatek: dpi: Add input_2pixel config support

2022-07-06T14:29:46+00:00

The input pixel per iteration could be different, so we add a new config
"input_2pixel" to control this.

drm/mediatek: dpi: Add config to support direct connection to dpi panels

2022-07-06T14:25:47+00:00

MediaTek dpi supports direct connection to dpi panels while dp_intf does
not support. Therefore, add a config "support_direct_pin" to control this.

drm/mediatek: dpi: Add YUV422 output support

2022-07-06T14:22:10+00:00

Dp_intf supports YUV422 as output format. In MT8195 Chrome project,
YUV422 output format is used for 4K resolution.

To support this, it is also needed to support color format transfer.
Color format transfer is a new feature for both dpi and dpintf of MT8195.

The input format could be RGB888 and output format for dp_intf should be
YUV422. Therefore, we add a mtk_dpi_matrix_sel() helper to update the
DPI_MATRIX_SET register depending on the color format.

drm: Remove linux/media-bus-format.h from drm_crtc.h

2022-07-05T18:15:13+00:00

drm_crtc.h has no need for linux/media-bus-format.h, so don't
include it. Avoids useless rebuilds of the entire universe when
touching linux/media-bus-format.h.

Quite a few placs do currently depend on linux/media-bus-format.h
without actually including it directly. All of those need to be
fixed up.

v2: Deal with ingenic as well
