Subject: [PATCH 0/5] drm/sun4i: Support LVDS on D1s/T113 combo D-PHY

Some Allwinner chips (notably the D1s/T113 and the A100) have a "combo
MIPI DSI D-PHY" which is required when using single-link LVDS0. The same
PD0..PD9 pins are used for either DSI or LVDS.

Other than having to use the combo D-PHY, LVDS output is configured in
the same way as on older chips.

This series enables the sun6i MIPI D-PHY to also work in LVDS mode. It
is then configured by the LCD TCON, which allows connecting a
single-link LVDS display panel.

Kuba Szczodrzyński (5):
  phy: allwinner: phy-sun6i-mipi-dphy: Support LVDS in combo D-PHY
  drm/sun4i: Support LVDS using MIPI DSI combo D-PHY
  drm/sun4i: Enable LVDS output on sun20i D1s/T113
  riscv: dts: allwinner: d1s-t113: Add D-PHY to TCON LCD0
  riscv: dts: allwinner: d1s-t113: Add LVDS0 pins
