As I can see now, this driver is quite a copy of fsl_pmic.c, with
slightly changes. Are you sure we cannot simply change the already
provided driver, adding support for the new chip ?

I have not read the DA9053 datasheet, but from your patch it seems to me
that the relevant changes are:
	- registers are 1 byte wide instead of 32 bit
	- different size of register area

Really not enough to justify a new driver. All functions are really
copied from the old one. Please consider to adapt fsl_pmic.c instead of
adding a slightly different new one.

Best regards,
Stefano Babic
