[Qemu-devel] [PULL v2 2/8] hw/mips_gictimer: provide API for retrieving frequency |

From: Paul Burton <address@hidden>
Provide a new function mips_gictimer_get_freq() which returns the
frequency at which a GIC timer will count. This will be useful for
boards which perform setup based upon this frequency.
