Detailed Description

This group contains the Armv7-AR/AArch64 Generic Timer Clock Driver implementation.

The BSP must provide the following function:

void arm_generic_timer_get_config(uint32_t *frequency, uint32_t *irq);

The BSP may optionally define ARM_GENERIC_TIMER_USE_VIRTUAL in <bsp.h> to use the virtual timer instead of the physical timer.
