2020-09-07regulator: remove locking around regulator_notifier_call_chain()Michał Mirosław1-4/+0
regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.

2020-01-13regulator: Convert i2c drivers to use .probe_newAxel Lin1-3/+2
Use the new .probe_new for i2c drivers. These drivers do not use const struct i2c_device_id * argument, so convert them to utilise the simplified i2c driver registration.

2016-07-15regulator: da9210: addition of device tree supportSteve Twiss1-2/+19
Addition of device tree support for DA9210. Two files are modified, the driver source file and the binding document. Updates for the regulator source file include an .of_match_table entry and node match checking in the probe() function for a compatible da9210 string. Minor binding documentation changes have been made to the title and the example.

2015-07-13regulator: da9210: Add optional interrupt supportGeert Uytterhoeven1-0/+75
Add optional interrupt support to the da9210 regulator driver, to handle over-current, under- and over-voltage, and over-temperature events. Only the interrupt sources for which we handle events are unmasked, to avoid interrupts we cannot handle.

2015-02-17regulator: da9210: Mask all interrupt sources to deassert interrupt lineGeert Uytterhoeven1-0/+9
After boot-up, some events may be set, and cause the da9210 interrupt line to be asserted. As the da9210 driver doesn't have interrupt support yet, this causes havoc on systems where the interrupt line is shared among multiple devices. This is the case on e.g. r8a7791/koelsch, where the interrupt line is shared with a da9063 regulator, and the following events are set: EVENT_A = 0x00000011 (GPI0 | GPI4) EVENT_B = 0x00000002 (NPWRGOOD) Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-26regulator: of: Add regulator desc param to of_get_regulator_init_data()Javier Martinez Canillas1-1/+1
The of_get_regulator_init_data() function is used to extract the regulator init_data but information on how to extract certain data is defined in the static regulator descriptor (e.g: how to map the hardware operating modes). Add a const struct regulator_desc * parameter to the function signature so the parsing logic could use the information in the struct regulator_desc. of_get_regulator_init_data() relies on of_get_regulation_constraints() to actually extract the init_data so it has to pass the struct regulator_desc but that is modified on a later patch.
