Subject: [PATCH] arm64: dts: rockchip: Fix sdmmc pwren pinctrl for rk3576-evb2
Date: Thu, 26 Feb 2026 18:20:52 +0800	[thread overview]
Message-ID: <20260226102052.63-1-kernel@airkyi.com> (raw)

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

In rk3576.dtsi, sdmmc0_pwren is configured as part of the sdmmc pinctrl.
However, on the rk3576 evb2 board, sdmmc0_pwren is used as the regulator
for vmmc-supply. Therefore, we need to reassign the sdmmc pinctrl and
remove sdmmc0_pwren to avoid conflicts.
