[PATCH v4 5/9] ARM: dts: rockchip: disable arm-global-timer for rk3188

Show all headers | View raw

arm-global-timer can provide clockevents, clocksource and shed_clock. But
on rk3188 platform it provide only clocksource and shed_clock. clockevents
from  arm-global-timer is not used by kernel because there is another
clockevent provider with higher rating (smp-twd).

My commit from the series implement clocksource and shed_clock using
rockchip_timer. But sched clock from rk_timer is not selected by kernel
due to lower frequency than arm-global-timer, and clocksource from
rk_timer is not selected by kernel due to lower rating than
arm-global-timer. And I don't want to increase clocksource rating
because ratings greater 300 used for high frequency clocksources.

clocksource and shed_clock is quite unstable, because their rate depends
on cpu frequency. So disable arm-global-timer and use clocksource and
sched_clock from rockchip_timer.
