I have tested the SPI part on a different board instead of
MX51EVK(vision2). I think you can forget for your patchset about MX5
boards - they can be switched to the general pmic_core when the fsl_pmic
file will be dropped and after merging your patches. Thanks in any case
to have provided an example ;-)

Ok - it will be removed after including you patches.

The write function is symmetric to the read function:

int pmic_reg_write(struct pmic *p, u32 reg, u32 *val)

However, we do not want to change the value pointed by val. I think it
is should better to pass a u32 instead of a pointer.

Logically I see your patchset split into 3 patches, but differently as
you did:
	- adding pmic core driver
	- adding support for max8998
	- adding pmic to the s5p_goni

Best regards,
