2012-04-04	regulator: gpio-regulator: Basic devm_kzalloc() conversion	Mark Brown
	There's some other allocations but they're not so trivial as they use kmemdup() and kstrdup(). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

	range Do not assume the gpio regulator states map is sorted in any order. This patch ensures we always set the smallest voltage/current that falls within the specified range.

2011-11-24	regulator: Fix compile break due to missing arguments to regulator_register	Rajendra Nayak
	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' include/linux/regulator/driver.h:215:23: note: declared here Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-10-09	regulator: Add driver for gpio-controlled regulators	Heiko Stübner
	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.
