[PATCH v0 0/2] Add sdmmc UHS support to ROC-RK3328-CC board

From: Levin Du <djw at t-chip.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.
