regulator: add warning flags

2021-06-21T12:08:38+00:00

Add 'warning' level events and error flags to regulator core. Current regulator core notifications are used to inform consumers about errors where HW is misbehaving in such way it is assumed to be broken/unrecoverable. There are PMICs which are designed for system(s) that may have use for regulator indications sent before HW is damaged so that some board/consumer specific recovery-event can be performed while continuing most of the normal operations. Add new WARNING level events and notifications to be used for that purpose.

regulator: consumer: Add missing stubs to regulator/consumer.h

2021-01-21T12:35:42+00:00

Add missing stubs to regulator/consumer.h in order to fix COMPILE_TEST of the kernel. In particular this should fix compile-testing of OPP core because of a missing stub for regulator_sync_voltage().

regulator: consumer: Supply missing prototypes for 3 core functions

regulator_suspend_enable(), regulator_suspend_disable() and regulator_set_suspend_voltage() are all exported members of the API, but are all missing prototypes.

regulator: core: Add regulator_is_equal() helper

2020-01-14T15:50:31+00:00

Add regulator_is_equal() helper to compare whether two regulators are the same. This is useful for checking whether two separate regulators in a driver are actually the same supply.

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

2019-09-03T11:37:16+00:00

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()

2019-09-02T11:49:42+00:00

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: Fix return value of _set_load() stub

2018-11-20T15:22:46+00:00

The stub implementation of _set_load() returns a mode value which is within the bounds of valid return codes for success (the documentation just says that failures are negative error codes) but not sensible or what the actual implementation does. Fix it to just return 0. Reported-by: Cheng-Yi Chiang Signed-off-by: Mark Brown Reviewed-by: Douglas Anderson Signed-off-by: Mark Brown
