* struct regulator_ops - regulator operations.
|
|
*
|
|
* This struct describes regulator operations which can be implemented by
|
|
* regulator chip drivers.
|
|
*
|
|
* @enable: Enable the regulator.
|
|
* @disable: Disable the regulator.
|
|
* @is_enabled: Return 1 if the regulator is enabled, 0 otherwise.
|
|
*
|
|
* @set_voltage: Set the voltage for the regulator within the range specified.
|
|
* The driver should select the voltage closest to min_uV.
|
|
* @get_voltage: Return the currently configured voltage for the regulator.
|
|
*
|
|
* @set_current_limit: Configure a limit for a current-limited regulator.
|
|
* @get_current_limit: Get the limit for a current-limited regulator.
|
|
*
|
|
* @set_mode: Set the operating mode for the regulator.
|
|
* @get_mode: Get the current operating mode for the regulator.
|
|
* @get_optimum_mode: Get the most efficient operating mode for the regulator
|
|
* when running with the specified parameters.
|
|
*
|
|
* @set_suspend_voltage: Set the voltage for the regulator when the system
|
|
* is suspended.
|
|
* @set_suspend_enable: Mark the regulator as enabled when the system is
|
|
* suspended.
|
|
* @set_suspend_disable: Mark the regulator as disabled when the system is
|
|
* suspended.
|
|
* @set_suspend_mode: Set the operating mode for the regulator when the
|
|
* system is suspended.
