[PATCH v3 6/6] arm64: dts: rockchip: add pinctrls for 16-bit/18-bit rgb interface to rk356x

From: Michael Riesch
Date: Tue Jan 24 2023 - 00:50:12 EST


The rk3568-pinctrl.dtsi only defines the 24-bit RGB interface. Add separate
nodes for the 16-bit and 18-bit version, respectively. While at it, split
off the clock/sync signals from the data signals.

The exact mapping of the data pins was discussed here:
