From 12049db764378c92d9cbec72b48f2a6df4e6ae27 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Tue, 15 Oct 2024 17:26:46 +0200 Subject: [PATCH] rockchip: rk3588-rock-5b: Add USB-C controller to u-boot.dtsi Add USB-C controller (fusb302), which will be used by U-Boot to initialize USB-PD. This is needed, because USB-PD communication must happen within 5 seconds after the USB-C connector got plugged. On my Rock 5B it often takes 5 seconds to jump to the Linux binary, so it must happen before Linux is initialized. This adds the DT node to the U-Boot specific file, since the Linux kernel DT currently does not describe it to avoid a system reset. The plan is to add it to the Linux DT with status = 'fail' and then let U-Boot mark it as status = 'okay' if it properly dealt with early USB-PD initialization. Until the Kernel DT has the node, let's add it in U-Boot to get things going.
