Hi,
I forgot to add some note to this patch...

why are these boolean? Can't we send whatever we read from the
register?

This mask is really weird! Sujaritha, can you please explain it?
It looks something like this,
REG_GENMASK(11, 6) | REG_GENMASK(2, 0)
But I don't know if it improves any readability, in any case, the
mask is not clear.

I hope I got these right. Sujaritha, can you please check?
