Hi Michael,

Could you add a commit message to all patches in this serie?

mmc aliases are sort on reg address based on availability without number
gap.

	sdmmc0: mmc@fe2b0000 {}
	sdhci: mmc@fe310000 {}

pinctrl-names below pinctrl-0 like the rest of rk356x.dtsi

Check mmc-controller.yaml, rockchip-dw-mshc.yaml and
synopsys-dw-mshc-common.yaml for properties.

Hi Johan,

Thanks for your comments, I'll try to implement the requested changes
and prepare a v3 tomorrow.

Well the short commit message (i.e., the subject line) pretty much wraps
it all up in my opinion, hence no need for an extended commit message.
Is there anything in particular you would like to see or have explained
that requires an extended message? I would like to refrain from adding
an extended commit message just for the sake of having one.

I'll turn these around.

I am afraid I don't quite follow. What exactly should I check? I am
pretty sure that the properties I used are described in the mentioned
yaml files.

it's just a matter of style, and yes having a non-empty commit message
is preferred in most parts of the kernel.

Even if it's just a simple one-liner ;-), for example

"Enable the sdmmc node on the rk3568-evb1 with the 4 lanes connected on it"
