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

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.

Michael Walle (4):
  dt-bindings: display: mediatek: dsi: add compatible for MediaTek
    MT8195
  dt-bindings: phy: add compatible for Mediatek MT8195
  arm64: dts: mediatek: mt8195: add DSI and MIPI DPHY nodes
  drm/mediatek: support the DSI0 output on the MT8195 VDOSYS0
