2021-06-01regulator: bd70528: Drop BD70528 supportMatti Vaittinen1-278/+0
The only known BD70528 use-cases are such that the PMIC is controlled from separate MCU which is not running Linux. I am not aware of any Linux driver users. Furthermore, it seems there is no demand for this IC. Let's ease the maintenance burden and drop the driver. We can always add it back if there is sudden need for it.

2021-01-05regulator: ROHM bd7xxxx: Do not depend on parent driver dataMatti Vaittinen1-8/+3
The ROHM PMIC regulator drivers only need the regmap pointer from the parent device. Regmap can be obtained via dev_get_regmap() so do not require parent to populate driver data for that.

2020-01-03regulator: bd70528: Remove .set_ramp_delay for bd70528_ldo_opsAxel Lin1-1/+0
The .set_ramp_delay should be for bd70528_buck_ops only. Setting .set_ramp_delay for for bd70528_ldo_ops causes problem because BD70528_MASK_BUCK_RAMP (0x10) overlaps with BD70528_MASK_LDO_VOLT (0x1f). So setting ramp_delay for LDOs may change the voltage output, fix it.
