This whole bunch of drivers is in the wrong place in Makefile.

hmm... So shall we need to cherry-pick your this patch first,
then modify the Makefile before the next submission??

I don't know what Lee's preferences are, but at least I have these
options in mind:
1) wait until Lee applies my series;
2) take that single patch to your tree as a precursor.

In the second case you will need to send the series with that patch as well.

+#define MT6370_REG_MAXADDR     0x1FF

Wondering if (BIT(10) - 1) gives a better hint on how hardware limits
this (so it will be clear it's 10-bit address).

well... This "0x1FF" is just a virtual mapping value to map the max
address of the PMU bank(0x1XX).
So, I feel its means is different from using (BIT(10) - 1) here.

Perhaps a comment then?

Redundant 'else'.

I'm not quite sure what you mean, so I made the following changes first.
------------------------------------
       if (ret < 0)
              return ret;
       if (ret != val_size)
              return -EIO;
------------------------------------
I don't know if it meets your expectations??

Yes.
