2017-04-25regulator: arizona-micsupp: Move pdata into a separate structureRichard Fitzgerald
In preparation for sharing this driver with Madera, move the pdata for the micsupp regulator out of struct arizona_pdata into a dedicated pdata struct for this driver. As a result the code in arizona_micsupp_of_get_pdata() can be made independent of struct arizona. This patch also updates the definition of struct arizona_pdata and the use of this pdata in mach-crag6410-module.c Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-03-29regulator: arizona-micsupp: Avoid potential memory leak reading init_dataCharles Keepax
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 functionsRichard Fitzgerald
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()Javier Martinez Canillas
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.
