Hi Beomho,
The code has below defines in include/linux/mfd/rt5033-private.h
#define RT5033_REGULATOR_BUCK_VOLTAGE_MAX 3000000U
#define RT5033_REGULATOR_LDO_VOLTAGE_MAX 3000000U
However, according to current settings in rt5033 regulator driver:
For LDOs, it can support up to
RT5033_REGULATOR_LDO_VOLTAGE_MIN + RT5033_REGULATOR_LDO_VOLTAGE_STEP *
(RT5033_REGULATOR_LDO_VOLTAGE_STEP_NUM - 1)
= 1200000 + 100000 * 31
= 4300000 (This is different from the define of
RT5033_REGULATOR_LDO_VOLTAGE_MAX)
The same issue for BUCKs.
I don't find the datasheet, can you check which part is incorrect that
causes the inconsistent?
Thanks,
Axel
