From df056584b1825957ad118b6c1084aae00b1fa0b7 Mon Sep 17 00:00:00 2001 From: Chukun Pan Date: Wed, 3 Dec 2025 20:03:22 +0800 Subject: [PATCH] board: rockchip: add HINLINK H28K The HINLINK H28K is a single board computer based on the RK3528 SoC. Add support for the HINLINK H28K board. Features tested on HINLINK H28K: - SD-card boot - eMMC boot - Ethernet Signed-off-by: Chukun Pan --- --- /dev/null +++ b/arch/arm/dts/rk3528-hinlink-h28k-u-boot.dtsi @@ -0,0 +1,11 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) + +#include "rk3528-u-boot.dtsi" + +&vdd_arm { + regulator-init-microvolt = <953000>;
