According to lp8755.h:Hi Axel.
enum lp8755_mphase_config {
MPHASE_CONF0,
MPHASE_CONF1,
MPHASE_CONF2,
MPHASE_CONF3,
MPHASE_CONF4,
MPHASE_CONF5,
MPHASE_CONF6,
MPHASE_CONF7,
MPHASE_CONF8,
MPHASE_CONF_MAX
};
MPHASE_CONF_MAX is 9, the mask for pchip->mphase should be 0x17.
Otherwise, we cannot differentiate MPHASE_CONF0 and MPHASE_CONF8.

Hi Daniel,
I don't have the datasheet, can you check if this patch is correct?
BTW, I'm Axel, not Alex.
Regards,
Axel
