This should not be in here.

Make sure all of these entries are still used.

You need some comments in here to explain what's going on.

Why isn't all of the above in a Regmap driver?

Surely this should be tabbed?

Why do the entries above not require fallthrough statements?

Define the magic number please?

Doesn't this mean that MT6360_SLAVE_PMU won't be processed?

Shouldn't this be MT6360_SLAVE_MAX?

Oh, I see.

So change MT6360_SLAVE_PMU to (MT6360_SLAVE_MAX - 1) or else it just
looks a little bit arbitrary and fragile.
