regulator: helper routine to extract regulator_init_data
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: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
