I’ve sent patch series for fixing that on rockchip SoC.
http://lists.infradead.org/pipermail/linux-rockchip/2016-November/013217.html
But the series contain fix only for rk3188, because I don’t have another rockchip
SoC. rk3288 and other could be easy fixed with dts files.
There are a lot of other platforms what probably use shed_clock and
clocksource form global-timer.
