[PATCH 00/10] RDA8810PL SD/MMC support

[Dang Huynh via B4 Relay]

This patch series aims to add SDMMC driver and various drivers required
for SDMMC controller to function.

This also fixed a bug where all the GPIO switched from INPUT to OUTPUT
after the GPIO driver probed or by reading the GPIO debugfs.

This patch series is a split from [1] to ease the maintainers.

Tested on Orange Pi 2G-IOT using a Buildroot environment.
