    Subject[RFCv5 PATCH 03/46] arm: vexpress: Add CPU clock-frequencies to TC2 device-tree
    Date
    From: Dietmar Eggemann <dietmar.eggemann@arm.com>

    To enable the parsing of clock frequency and cpu efficiency values
    inside parse_dt_topology [arch/arm/kernel/topology.c] to scale the
    relative capacity of the cpus, this property has to be provided within
    the cpu nodes of the dts file.

    The patch is a copy of commit 8f15973ef8c3 ("ARM: vexpress: Add CPU
    clock-frequencies to TC2 device-tree") taken from Linaro Stable Kernel
    (LSK) massaged into mainline.
