[PATCH 0/4] drm/mediatek: support DSI output on MT8195

[PATCH 0/4] drm/mediatek: support DSI output on MT8195

[Michael Walle]

Add support for a DSI output on VDOSYS0. Luckily, there is a new
feature to support dynamic selections of the output (connector).
Use it to add support for a DSI output.

Apart from that, this is pretty straghtforward by just adding new
compatibles and add the correct DSI nodes to the SoC dtsi.

This was tested with a Toshiba TC358775 DSI-to-LVDS bridge and
three different panels. Please note, that the driver for this
bridge doesn't work well and needs a more or less complete rework,
which will be posted on a separate series.

[PATCH 4/4] drm/mediatek: support the DSI0 output on the MT8195 VDOSYS0

[Michael Walle]

With the latest dynamic selection of the output component, we can now
support different outputs. Move current output component into the
dynamic routes array and add the new DSI0 output.

I checked all the address ranges and interrupt values and they are all
correct. The other bits seem to be correct, extrapolating from previous
chips such as MT8183 and MT8192.

Please disregard this patch (the others are ok). There must gone 
something
wrong during my testing. DDP_COMPONENT_MERGE0 won't work with
DDP_COMPONENT_DSI0. If anyone has more insights, I'm all ears.

I was *convinced* that the MERGE0 SOUT was connected to DSI0!!!

...but you're right, here, and thanks for catching that: there's no way to
get MERGE0 connected to DSI0; if you check in the datasheet for VDO_SEL_IN,
you can get data from MERGE0 only for DSI*1*, not 0.

The only way is to connect DSC_WRAP0 (DDP_COMPONENT_DSC0 in mtk_drm_drv btw)
directly to DSI0 (or dither to dsi0)... unless there is a way to change the
pinmux to invert the pins for DSI0/1?

You could assign the DSI1 controller to the one that is currently DSI0 for you.

That would solve the issue here.

Cheers!
