regulator: bd718x7: support ROHM BD71837 and BD71847 PMICs

2019-07-19T13:18:47Z

BD71837 and BD71847 is PMIC intended for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847 is used for example on NXP imx8mm EVK. Add regulator driver for ROHM BD71837 and BD71847 PMICs. BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced version containing 6 bucks and 6 LDOs. Voltages for DVS bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted when regulators are enabled. For other bucks and LDOs we may have over- or undershooting if voltage is adjusted when regulator is enabled. Thus this is prevented by default. BD718x7 has a quirk which may leave power output disabled after reset if enable/disable state was controlled by SW. Thus the SW control is only allowed for BD71837 bucks 3 and 4 by default. The impact of this limitation must be evaluated board-by board and restrictions may need to be modified. (Linux driver get's these limitations from DT and we may want to implement same on u-Boot driver). Signed-off-by: Matti Vaittinen Reviewed-by: Simon Glass

regulator: Allow enabling GPIO regulator

2019-07-18T15:31:25Z

Drivers need to be able to enable regulators that may be implemented as GPIO regulators. Example: fsl_esdhc enables the vqmmc supply which is commonly implemented as a GPIO regulator in order to switch between I/O voltage levels. Signed-off-by: Sven Schwermer Reviewed-by: Lukasz Majewski

regulator: Factor out common enable code

2019-07-18T15:31:24Z

In preparation of being able to enable/disable GPIO regulators, the code that will be shared among the two kinds to regulators is factored out into its own source files. Signed-off-by: Sven Schwermer Reviewed-by: Lukasz Majewski

regulator: Allow autosetting fixed regulators

2019-07-13T15:11:31Z

Fixed regulators don't have a set_value method. Therefore, trying to set their value will always return -ENOSYS. Signed-off-by: Sven Schwermer Cc: Jaehoon Chung Cc: Peng Fan Reviewed-by: Simon Glass

power: regulator: Kconfig: Add SPL_DM_REGULATOR configs for palmas/lp873x/lp87565

2019-07-13T15:11:29Z

Add SPL_DM_REGULATOR configs for palmas/lp873x/lp87565. These were missing and the Makefile already assumes them to be defined. Add the corresponding SPL config options. This enables the regulator support in SPL. Signed-off-by: Keerthy

power: pfuze100: Fix off by one error in voltage table handling

2019-06-11T08:42:48Z

The code that sets a regulator by looking up the voltage in a table had an off by one error. vsel_mask is a bitmask, not the number of table entries, so a vsel_mask value of 0x7 indicates there are 8, not 7, entries in the table. Cc: Peng Fan Cc: Jaehoon Chung Signed-off-by: Trent Piepho
