ARM: rockchip: enable arm-global-timer
From: Heiko Stuebner <heiko@...> Date: Mon, 30 Sep 2013 16:29:55 +0200
Commit-Message
RK2928 and RK3066 contain a dw_apb timer component, while the rk3188 uses a slightly similar but still different timer component. But all of them support the ARM-global-timer that got added as clocksource driver recently. So enable support for it to get a working clocksource for rk3188. Signed-off-by: Heiko Stuebner <heiko@...>
