regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_id

2019-11-07T13:10:08Z

Those regulators are not actually supported by the AB8500 regulator driver. There is no ab8500_regulator_info for them and no entry in ab8505_regulator_match. As such, they cannot be registered successfully, and looking them up in ab8505_regulator_match causes an out-of-bounds array read.

regulator: ab8500: Remove AB8505 USB regulator

2019-11-07T13:09:58Z

The USB regulator was removed for AB8500 in commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator"). It was then added for AB8505 in commit 547f384f33db ("regulator: ab8500: add support for ab8505"). However, there was never an entry added for it in ab8505_regulator_match. This causes all regulators after it to be initialized with the wrong device tree data, eventually leading to an out-of-bounds array read. Given that it is not used anywhere in the kernel, it seems likely that similar arguments against supporting it exist for AB8505 (it is controlled by hardware). Therefore, simply remove it like for AB8500 instead of adding an entry in ab8505_regulator_match.

regulator: fixed: add off-on-delay

2019-10-29T12:32:12Z

Depends on board design, the gpio controlling regulator may connects with a big capacitance. When need off, it takes some time to let the regulator to be truly off. If not add enough delay, the regulator might have always been on, so introduce off-on-delay to handle such case.

regulator: add missing 'static inline' to a helper's stub

2019-09-03T11:37:16Z

The build fails when CONFIG_REGULATOR is not selected because the stub for regulator_bulk_set_supply_names() is missing the 'static inline' attribute. Signed-off-by: Bartosz Golaszewski Link: https://lore.kernel.org/r/20190902151332.28058-1-brgl@bgdev.pl Signed-off-by: Mark Brown

regulator: provide regulator_bulk_set_supply_names()

2019-09-02T11:49:42Z

There are many regulator consumers who - before using the regulator bulk functions - set the supply names in regulator_bulk_data using a for loop. Let's provide a simple helper in the consumer API that allows users to do the same with a single function call.

regulator: mt6358: Add support for MT6358 regulator

2019-08-28T10:51:27Z

The MT6358 is a regulator found on boards based on MediaTek MT8183 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.

regulator: implement selector stepping

2019-07-04T16:07:25Z

Some regulators require that the requested voltage be reached gradually by setting all or some of the intermediate values. Implement a new field in the regulator description struct that allows users to specify the number of selectors by which the regulator API should step when ramping the voltage up/down.
