I'm slightly confused here: I thought this driver was hisilicon specific.
Is the MMIO register layout that is used in this hardware actually standardized
in a way that the driver also works for all other implementations?

Please make all function definitions 'static' so we don't accidentally get
other users that bypass the proper interface.
