From e3cdadc325004c66359204de4b7309cd8b65beb9 Mon Sep 17 00:00:00 2001 From: Cristian Ciocaltea Date: Thu, 29 May 2025 19:31:51 +0300 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.
