2022-11-22regulator: arizona-micsupp: Don't use a common regulator nameGravatar Richard Fitzgerald 1-1/+4
The Arizona and Madera codecs all have a datasheet name of "MICVDD" for the regulator output. But future codecs with a regulator that can be controlled by this driver have different naming convention for the output of the regulator. Move the setting of the supply name from arizona_micsupp_common_init() to arizona_micsupp_probe() and madera_micsupp_probe().

2022-11-22regulator: arizona-micsupp: Don't hardcode use of ARIZONA definesGravatar Richard Fitzgerald 1-8/+7
When Madera support was added to this driver the code was left using ARIZONA_* defines. This wasn't causing any problem because those defines just happened to have the same value as the equivalent MADERA_* defines. But it is not ideal to assume this, and future devices that can share this driver do not have the same register map. Fix the code to refer to the register data in struct regulator_desc.

2017-03-29regulator: arizona-micsupp: Avoid potential memory leak reading init_dataGravatar Charles Keepax 1-4/+5
The device argument passed to of_get_regulator_init_data is used to do some devres memory allocation. Currently the driver passes the MFD device pointer to this function, this could result in the init_data allocation being leaked if the regulator is unbound but the MFD isn't. Correct this issue by correctly passing the local platform device. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-12-15regulator: arizona-micsupp: Use SoC component pin control functionsGravatar Richard Fitzgerald 1-2/+4
The name of a codec pin can have an optional prefix string, which is defined by the SoC machine driver. The snd_soc_dapm_x_pin functions take the fully-specified name including the prefix and so the existing code would fail to find the pin if the audio machine driver had added a prefix. Switch to using the snd_soc_component_x_pin equivalent functions that take a specified SoC component and automatically add the name prefix to the provided pin name.

2014-11-26regulator: of: Add regulator desc param to of_get_regulator_init_data()Gravatar Javier Martinez Canillas 1-3/+5
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.
