This driver supports RK805, RK809 and RK817, RK808 and RK818 crystal oscillator clock.
These multi-function devices have two fixed-rate oscillators, clocked at 32KHz each.

Select this option to enable power key driver for RK805.
Additional drivers must be enabled in order to use the
different functionality of the device.
