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
