Subject: arm64: dts: rockchip: Fix sdmmc pwren pinctrl for rk3576-evb2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7d939032bd7e203e1c907a8c35e3672eeee08246;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: rockchip: Fix sdmmc pwren pinctrl for rk3576-evb2

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.
