2012-04-05Regulator: gpio_swtich: Remove gpio_switch regulator driverLaxman Dewangan
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.

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.

commit ba305e31e88ea5c2f598ff9fbc5424711a429e30 upstream. SMPS regulator voltage control differs from the one of the LDO ones. Current TWL code was using LDO regulator ops for controlling the SMPS regulators, which fails. This was fixed fixed by adding separate regulator type which uses correct logic and calculations for the voltage levels.
