2011-11-28regulator: twl: fix twl4030 support for smps regulatorsTero Kristo1-2/+44
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.

2011-11-28regulator: fix use after free bugLothar Waßmann1-1/+1
This is caused by dereferencing 'rdev' after device_unregister() in the regulator_unregister() function. 'rdev' is freed by device_unregister(), so it must not be dereferenced after this call.

2011-11-23regulator: TPS65910: Fix VDD1/2 voltage selector countAfzal Mohammed1-6/+8
Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-10-09regulator: Add driver for gpio-controlled regulatorsHeiko Stübner3-0/+367
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.

2011-09-14regulator: Implement deferred disable supportMark Brown1-0/+59
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().
