Are you sure that this is true for all devices that might be supported
by the driver (I'm guessing there may be other variants)?  There's often
a drift between silicon and package revisions which gets papered over by
datasheets and ignored by drivers.

Don't include a series of random unrelated changes in a single patch,
split them up into separate patches.  This makes review much easier if
nothing else.  There's no overlap at all between this change and the one
above.  The change is sensible.

You've also got this again unrelated change which isn't mentioned in the
changelog at all.
