Hi Angelo,

The clock architecture may vary depending on the platform.
These clock patch look good to me.

I want to clarify that I am not opposing this in order to keep the 
low quality of the driver for the sake of easier downstream porting.
My objection is purely due to the quality of this patch:
https://lore.kernel.org/all/eb47587159484abca8e6d65dddcf0844822ce99f.camel@mediatek.com/
Originally, this could have been a simple matter handled by a single
DTS setting,
but this patch requires checking a bunch of DTS voltage settings.
This increases the complexity of the boot process, and I don't see any
benefit from it.

Even though I think the other patches look good to me, I haven't seen
any new ones uploaded.
I would like to reiterate that I welcome any upstream contributions
related to Linux UFS on MediaTek platforms.

Thanks
Peter
