Please make the entire header a C++ comment so that it looks intentional
rather than mixing C and C++ like this.

Could you use a MMIO regmap for this driver? All the operations look
like they're just straight up operations of the sort the standard
helpers support them and it means the driver will be able to take
advantage of any improvements the core makes for free.
Otherwise this looks great, and the above two issues can be fixed as
followup patches so I'll apply.
