Subject: [PATCH 102/110] [WIP-FRL] arm64: dts: rockchip: Add tmds-enable-gpios
|
|
to rk3588-rock-5b
|
|
|
|
In preparation to support HDMI 2.1 FRL operating mode, make use of the
|
|
GPIO4_B1 and GPIO4_A1 lines (labeled HDMI0_TX_ON_H & HDMI1_TX_ON_H in
|
|
the schematics) required to control the level shifters for HDMI0 and
|
|
HDMI1 data lines, respectively.
|
|
|
|
The lines will be asserted when operating in TMDS mode and deasserted
|
|
when switching to FRL.
