2012-07-02regulator: tps80031: support for min voltage toleranceLaxman Dewangan
Sometimes the system allow to run in less than requested minimum voltage and if this tolerance allow the regulator to set voltage in lower side range than this saves the power. For the example, if client request vmin = 975mV for regulator voltage then it sets the voltage to 987.5mv as the nearest to this desired value. The next lower side for the voltage is 974.8mv. So if system runs on tolerance of 1mv and if it request for 975mv then driver can look for minimum voltage as 975 - tolerance(1) = 974mv and possible configure 974.8mv rather than 987.5mV and so it can save the power equivalent to 12.5mV higher voltage. Support the configuration of tolerance value.

2012-01-19regulator: Add driver for gpio-controlled regulatorsHeiko 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.
