This adds the mmc node for the StarFive JH7110 SoC.
Set mmco node to emmc and set mmc1 node to sd.

Do not use "This xxx". Use imperative mode.

No:
1. Undocumented.
2. A bit too generic. You should have here SoC specific compatible as
well (either as second or third compatible, if all your SoCs share
register layout).

Hi Krzysztof,

As for the compatible, I will change it to "starfive,jh7110-sysreg"
in next version,but for undocumented, I don't get it, can you
clarify that.
Thank you anyway.

You need bindings for it. I don't see it in linux-next, cover letter
dependencies nor here.

I see, I will update it in next version.
Thank you for taking time to review and provide helpful comments for this patch.

Please add these so they're sorted alphabetically (but keep the clocks
at the top), so there's at least some sort of system.

This may need updating depending on whether you fix the driver or bindings.
