RK1108 is embedded with an ARM Cortex-A7 single core and a DSP core.
It is designed for varies application scenario such as car DVR, sports
DV, secure camera and UAV camera.
This patch series add basic support for it, which can boot a board with
initramfs into shell.
More new feathers will come soon.

Changes in v2:
- split dt-binding header from clk driver
- fix some CodingStyle issues
- add dt-binding documentation for pinctrl
- add pull and drive-strength functionality for pinctrl
- fix timer and gic dt description
- ordering devices by register address
- move the board in the rockchip.txt to the block of Rockchip boards

Andy Yan (6):
  dt-bindings: add documentation for rk1108 pinctrl
  pinctrl: rockchip: add support for rk1108
  ARM: add low level debug uart for rk1108
  ARM: dts: add basic support for Rockchip RK1108 SOC
  ARM: rockchip: enable support for RK1108 SoC
  ARM: dts: rockchip: add rockchip RK1108 Evaluation board

Shawn Lin (4):

pmu_1f, usbphy and hdmiphy do not seem to be used in this driver, while they 
are specified in the clock documentation.

Also there is a discrepancy between your pmu_24m and pmu_24m_ena below I 
think.


The rest looks sane but I didn't check every register offset :-) .
