2014-07-25regulator: Add helpers for low-level register accessTuomas Tynkkynen1-0/+35
Add helper functions that allow regulator consumers to obtain low-level details about the regulator hardware, like the voltage selector register address and such. These details can be useful when configuring hardware or firmware that want to do low-level access to regulators, with no involvement from the kernel. The use-case for Tegra is a voltage-controlled oscillator clocksource which has control logic to change the supply voltage via I2C to achieve a desired output clock rate.

2011-12-05regulator: Fix regulator_register() API signature in DocumentationRajendra Nayak1-1/+1
The commit 2c043bcbf287 ("regulator: pass additional of_node to regulator_register()") added an additional parameter to the regulator_register() API.

2011-10-07regulator: Clarify documentation for regulator-regulator suppliesMark Brown1-2/+9
The mechanism used for connecting regulators together when one regulator supplies another wasn't clear as the names being used weren't really tied together well. Reported-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-07regulator: Fix some bitrot in the machine driver documentationMark Brown1-4/+4
The documentation for the machine driver was rather badly bitrotted, using pointers to struct device rather than dev_name() to hook up the consumers. Update to use dev_name(). Reported-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-05-27regulator: Remove supply_regulator_dev from machine configurationMark Brown1-2/+2
supply_regulator_dev (using a struct pointer) has been deprecated in favour of supply_regulator (using a regulator name) for quite a few releases now with a warning generated if it is used and there are no current in tree users so just remove the code.

2008-10-14regulator: core - Rework machine API to remove string based functions.Liam Girdwood2-78/+70
This improves the machine level API in order to configure regulator constraints and consumers as platform data and removes the old string based API that required several calls to set up each regulator. The intention is to create a struct regulator_init_data, populate it's fields with constraints, consumers devices, etc and then register the regulator device from board.c in the standard Linux way. e.g. regulator LDO2 (supplying codec and sim) platform data. /* regulator LDO2 consumer devices */ static struct regulator_consumer_supply ldo2_consumers[] = { { .dev = &platform_audio_device.dev, .supply = "codec_avdd", }, { .dev = &platform_sim_device.dev, .supply = "sim_vcc", } }; /* regulator LDO2 constraints */ static struct regulator_init_data ldo2_data = { .constraints = { .min_uV = 3300000, .max_uV = 3300000, .valid_modes_mask = REGULATOR_MODE_NORMAL, .apply_uV = 1, }, .num_consumer_supplies = ARRAY_SIZE(ldo2_consumers), .consumer_supplies = ldo2_consumers, }; /* machine regulator devices with thier consumers and constraints */ static struct platform_device wm8350_regulator_devices[] = { { .name = "wm8350-regulator", .id = WM8350_LDO_2, .dev = { .platform_data = &ldo2_data, }, }, }; Changes in detail:- o Removed all const char* regulator config functions in machine API. o Created new struct regulator_init_data to contain regulator machine configuration constraints and consmuers. o Changed set_supply(), set_machine_constraints(), set_consumer_device_supply() to remove their string identifier parameters. Also made them static and moved functions nearer top of core.c. o Removed no longer used inline func to_rdev() o Added regulator_get_init_drvdata() to retrieve init data. o Added struct device* as parameter to regulator_register(). o Changed my email address.
