regulator: ab8500: Decomission platform data header

2021-01-13T11:36:19Z

The platform data header was only used to pass platform data from board files. We now populate the regulators exclusively from device tree, so the header contents can be moved into the regulator drivers.

regulator: ab8500: Remove unused platform data

2021-01-13T11:36:18Z

The struct ab8500_regulator_platform_data was a leftover since the days before we probed all regulators from the device tree. The ab8500-ext regulator was the only used, defining platform data and register intialization that was never used for anything, a copy of a boardfile no longer in use. Delete the ab8500_regulator_platform_data and make the ab8500-ext regulator reference the regulator init data in the local file directly. We are 100% device tree these days.

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: ab8500: Drop AB8540/9540 support

2018-04-16T12:08:59Z

The AB8540 was an evolved version of the AB8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the AB8500.

regulator: ab8500-ext: Register as a device in its own right

2013-06-11T11:50:00Z

Some platforms don't support the AB8500 external regulators, so instead of having a list of is_() calls prior to calling ab8500_ext_regulator_init() from ab8500_regulator_probe(), we can only register as a platform device on platforms which require them. It means we also have more control over them when booting with Device Tree. Signed-off-by: Lee Jones Signed-off-by: Mark Brown
