Merge tag 'v3.11-rockchip-basics' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/soc
From Heiko Stuebner:
Adds basic support for Rockchip Cortex-A9 SoCs.
* tag 'v3.11-rockchip-basics' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
arm: add basic support for Rockchip RK3066a boards
arm: add debug uarts for rockchip rk29xx and rk3xxx series
arm: Add basic clocks for Rockchip rk3066a SoCs
clocksource: dw_apb_timer_of: use clocksource_of_init
clocksource: dw_apb_timer_of: select DW_APB_TIMER
clocksource: dw_apb_timer_of: add clock-handling
clocksource: dw_apb_timer_of: enable the use the clocksource as sched clock
