/**
 * struct gpio_regulator_config - config structure
 * @supply_name:	Name of the regulator supply
 * @input_supply:	Name of the input regulator supply
 * @enabled_at_boot:	Whether regulator has been enabled at
 *			boot or not. 1 = Yes, 0 = No
 *			This is used to keep the regulator at
 *			the default state
 * @startup_delay:	Start-up time in microseconds
 * @gflags:		Array of GPIO configuration flags for initial
 *			states
 * @ngpios:		Number of GPIOs and configurations available
 * @states:		Array of gpio_regulator_state entries describing
 *			the gpio state for specific voltages
 * @nr_states:		Number of states available
 * @regulator_type:	either REGULATOR_CURRENT or REGULATOR_VOLTAGE
 * @init_data:		regulator_init_data
 *
 * This structure contains gpio-voltage regulator configuration
 * information that must be passed by platform code to the
 * gpio-voltage regulator driver.
