With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

The helper routine is meant to be used by the regulator drivers to extract the regulator_init_data structure from the data that is passed from device tree. 'consumer_supplies' which is part of regulator_init_data is not extracted as the regulator consumer mappings are passed through DT differently, implemented in subsequent patches. Similarly the regulator<-->parent/supply mapping is handled in subsequent patches. Also add documentation for regulator bindings to be used to pass regulator_init_data struct information from device tree. Some of the regulator properties which are linux and board specific, are left out since its not clear if they can be in someway embedded into the kernel or passed in from DT. They will be revisited later. Signed-off-by: NRajendra Nayak <rnayak@ti.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Now that we have a shared API between the DB8500 and DB5500 PRCMU's, switch to using this neutral API instead. We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

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.

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().
