[PATCH 0/5] arm64: dts: rockchip: rk3568-evb1-v10: add sd card support

[PATCH 0/5] arm64: dts: rockchip: rk3568-evb1-v10: add sd card support

[Michael Riesch]

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, this depends on the
patch "soc: rockchip: io-domain: add rk3568 support" [1].

Best regards,
Michael

what is this supposed to do?

I don't think "emmc" is defined as any form of alias, instead
mmc aliases generally are more "mmcX" for X 0,1,etc .

same thing as in the previous patch.

I guess you may want something like

	mmc0 = &sdhci;
	mmc1 = &sdmmc0;

maybe?
