Subject: [PATCH v0 0/2] Add sdmmc UHS support to ROC-RK3328-CC board
From: Levin Du <djw@...hip.com.cn>
Hi all,
This is an attemp to add sdmmc UHS support to the ROC-RK3328-CC board.
It adds a new compatible `rockchip,rk3328-gpio-syscon10` to the gpio-syscon
driver, so that a new gpio controller named `gpio_syscon10` can be defined
and used in the regulator-gpio. This regulator controls the signal voltage of the
sdmmc. It is essential for UHS support which requires 1.8V signal voltage.
Levin Du (2):
gpio: syscon: Add gpio-syscon for rk3328
arm64: dts: rockchip: Add sdmmc UHS support for roc-rk3328-cc
