[PATCH v3 3/8] arm64: dts: ti: k3-am62x-sk-common: Add DSS pinmux info
Posted by Aradhya Bhatia 2 years, 6 months ago 
Add pinmux info for video output signals from DSS and OLDI.

The DSS outputs OLDI signals through its first video port (VP1) and DPI
signals via its second video port (VP2). DSS has 2 OLDI transmitters,
and each of them outputs 4 Data Lanes and 1 Clock Lane. The DPI output
from DSS is 24 bits (RGB888) and is forwarded to an HDMI transmitter
(SIL9022) on the board.

No. pinctrl-0 cells is 1.
pinctrl-0 = <&main_dss0_pins_default>, <&main_oldi0_pins_default>;
