      regulator: Add driver for gpio-controlled regulators · 3f0292ae
      由 Heiko Stübner 提交于 
      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: remove duplicate REG_CTRL2 defines in tps65023 · e3efe666
      由 H Hartley Sweeten 提交于 
      There are two sets of defines for the REG_CTRL2 bitfields and one
of them has TPS65023_REG_CTRL2_DCDC1 defined incorrectly. Remove
the duplicates and leave the correct one for TPS65023_REG_CTRL2_DCDC1.

This fixes the following sparse warnings:

drivers/regulator/tps65023-regulator.c:77:9: warning: preprocessor token TPS65023_REG_CTRL2_DCDC1 redefined
drivers/regulator/tps65023-regulator.c:70:9: this was the original definition

      regulator: Implement deferred disable support · da07ecd9
      由 Mark Brown 提交于 
      It is a reasonably common pattern for hardware to require some delay after
being quiesced before the disable has finalised, especially in mixed signal
devices. For example, an active discharge may be required to ensure that
the circuit starts up again in a known state. Avoid having to implement
such delays in the regulator API by providing regulator_deferred_disable()
which will do a regulator_disable() a specified number of milliseconds
after it is called.

Due to the reference counting done on regulators a deferred disable can
be cancelled by doing another regulator_enable().
