* regulator: tps65910: Sleep control through external inputsLaxman Dewangan2012-01-301-0/+206
| | | | | | | | | | | | | Add support for sleep controls of different regulator through external inputs EN1, EN2 or EN3. Each regulator's output will be active when its external input is high and turns to OFF/Low power mode when its external input is low. The configuration parameters for sleep control is provided through board specific platform data.

| | | | | | | | | | | | | As we progress with DB5500 and future voltage domain regulators based on very similar hardware as found in the DB8500 PRCMU, it makes sense to split off the generic parts and introduce some generic debug code for the DBx500 regulators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not always true that the device_node of regulator can be found at dev->of_node at the time when of_get_regulator_init_data() is being called, because in some cases the regulator nodes in device tree do not have 'struct device' behind them until regulator_dev gets created for it by core function regulator_register(). The patch adds device_node as a new parameter to of_get_regulator_init_data(), so that caller can pass in the node of regulator directly.
