Hi all,
This series enables the SD card reader on the RK3568 EVB1
and completes the support for the on-board eMMC.
As the PMU IO domains are required, the patch series that
introduces support for the RK3568 [1] has been integrated
in this series to bring this mainline.
Best regards,
Michael
[1] https://patchwork.kernel.org/project/linux-rockchip/list/?series=489383
v2:
- rename alias to match convention
- add support for rk3568 io domains
