maintainerv6 cover arm: add basic support for Rockchip Cortex-A9 SoCs
Sixth version of basic Rockchip A9 support.
This time again using the regular gate clocks as the driver got accepted into the clock tree.
Changes since v5:
- reintroduce the use of the gate clocks
Changes since v4:
- remove ifdef around l2x0 init
- only use dummy clocks
Changes since v3:
- split out standalone dw_mmc patches (submitted to linux-mmc)
- Remove divider and mux clocks and use fixed rate clocks instead until divider and mux clocks have got their generic dt bindings
- Make the gate clock use CLK_OF_DECLARE and document the bindings
Changes since v2:
- use common (pending review) HIWORD_MASK clock flag from Haojian Zhuang and me
- pinctrl driver is already in the pinctrl tree
- add core-periph clock that supplies the twd
- split "mmc: dw_mmc-pltfm: add Rockchip variant" into move and feature parts as suggested by Andy Shevchenko
Changes since v1:
- addressed Linus Walleij's comments to the pinctrl driver, including the move to generic pinconfig (hopefully I did catch all)
- renamed the clocks to use the SoC name of the initial user as suggested by Olof Johansson
- fixed the uart address, found by Arnd Bergmann
- address Arnd's comments on the board file (use of_clk_init and friends, remove map_io, use real soc names)
- removed Makefile.boot as suggested by Thomas Petazzoni

maintainerPATCH v6 1/3 arm: Add basic clocks for Rockchip rk3066a SoCs
This adds a basic clock setup for rk3066a SoCs. Only the gates are set up currently, as the mux and dividers should use the upcoming generic devicetree bindings.
Clocks whose rates need to be known are supplied by fixed-rate "dummy"-clocks that provide the correct rate. This is uncritical insofar that the only bootloader currently in existence for Rockchip devices is the propietary Rockchip one that always setups the clocks in the necessary way.

Looks good to me. As I mentioned previously we might be able to convert the rockchip,rk2928-gate-clk stuff over to the generic gate-clock binding once hiword-mask support and support for clock-cells == 1 is added in. I'm hacking on the former now and the latter may go in for 3.12.

maintainerPATCH v6 2/3 arm: add debug uarts for rockchip rk29xx and rk3xxx series
In reply to Heiko StübnerUarts on all recent Rockchip SoCs are Synopsis DesignWare 8250 types. Only their addresses vary very much.
This patch adds the necessary definitions to use any of the uart ports for early debug purposes.

maintainerPATCH v6 3/3 arm: add basic support for Rockchip RK3066a boards
In reply to Heiko StübnerThis adds a generic devicetree board file and a dtsi for boards based on the RK3066a SoCs from Rockchip.
Apart from the generic parts (gic, clocks, pinctrl) the only components currently supported are the timers, uarts and mmc ports (all DesignWare- based).
