Subject[PATCH v2 01/16] reset: add non CONFIG_RESET_CONTROLLER routines
Date
Some drivers are shared between platforms that may or may not
have RESET_CONTROLLER selected for them. Add dummy functions
when RESET_CONTROLLER is not selected, thereby eliminating the
need for drivers to enclose reset_control_*() calls within
#ifdef CONFIG_RESET_CONTROLLER, #endif
