regulator: Add support for RICOH PMIC RC5T583 regulator

2012-06-03T15:07:56+00:00

The RC5T583 PMIC from RICOH consists of 4 DCDC and 10
LDOs. This driver supports the control of different
regulator output through regulator interface.
This driver depends on MFD driver of RC5T583 and uses
mfd rc5t583 apis to communicate to device for accessing
different device's registers.

Regulator: gpio_swtich: Remove gpio_switch regulator driver

2012-04-05T16:08:55+00:00

The gpio_switch regulator is NV driver developed during
tegra3 bringup time. The driver functionality is upstreamed
to mainline into fixed regulator and it is accepted by community.
The required functionality is also downstream and required client
driver is moved to use the fixed  regulator. Hence this driver
is just duplicating functionality with fixed regulator and hence
removing this.

regulator: Add driver for gpio-controlled regulators

2012-01-19T18:29:01+00:00

This patch adds support for regulators that can be controlled via gpios.

Examples for such regulators are the TI-tps65024x voltage regulators
with 4 fixed and 1 runtime-switchable voltage regulators
or the TI-bq240XX charger regulators.

The number of controlling gpios is not limited, the mapping between
voltage/current and target gpio state is done via the states map
and the driver can be used for either voltage or current regulators.

A mapping for a regulator with two GPIOs could look like:

gpios = {
	{ .gpio = GPIO1, .flags = GPIOF_OUT_INIT_HIGH, .label = "gpio name 1" },
	{ .gpio = GPIO2, .flags = GPIOF_OUT_INIT_LOW,  .label = "gpio name 2" },
}

The flags element of the gpios array determines the initial state of
the gpio, set during probe. The initial state of the regulator is also
calculated from these values

states = {
	{ .value = volt_or_cur1, .gpios = (0 << 1) | (0 << 0) },
	{ .value = volt_or_cur2, .gpios = (0 << 1) | (1 << 0) },
	{ .value = volt_or_cur3, .gpios = (1 << 1) | (0 << 0) },
	{ .value = volt_or_cur4, .gpios = (1 << 1) | (1 << 0) },
}

The target-state for the n-th gpio is determined by the n-th bit
in the bitfield of the target-value.

regulator: Fix compile break due to missing arguments to regulator_register

The commit 2c043bcbf287 ("regulator: pass additional of_node to
regulator_register()") caused a compile break because it missed
updating the regulator_register() call in gpio-regulator.c with
the additional parameter (NULL).

The compile break as reported by Stephen Rothwell with the
x86_64 allmodconfig looked like this

drivers/regulator/gpio-regulator.c: In function 'gpio_regulator_probe':
drivers/regulator/gpio-regulator.c:287:8: error: too few arguments to function 'regulator_register'
