[PATCH v6 2/2] arm64: dts: ti: k3-am62l3-evm: Add HDMI support

[Swamil Jain]

From: Devarsh Thakkar <devarsht at ti.com>

Add the SII9022 HDMI bridge and HDMI connector nodes, along with the
DPI pinmux configuration connecting VOUT0 to the bridge. Enable the DSS
and hook up its DPI output port to the SII9022 bridge input, and the
bridge output to the HDMI connector.
