    Subject[PATCH AUTOSEL for 4.9 124/219] ARM: dts: rockchip: disable arm-global-timer for rk3188
    Date
    From: Alexander Kochetkov <al.kochet@gmail.com>

    [ Upstream commit 500d0aa918a2ea6bb918fee8adcf27dc2912bcd1 ]

    The clocksource and the sched_clock provided by the arm_global_timer
    are quite unstable because their rates depend on the cpu frequency.

    On the other side, the arm_global_timer has a higher rating than the
    rockchip_timer, it will be selected by default by the time framework
    while we want to use the stable rockchip clocksource.

    Let's disable the arm_global_timer in order to have the rockchip
    clocksource selected by default.
