arm: add basic support for Rockchip Cortex-A9 SoCs

A patchset in state Mainline for linux-kernel

Prepare your eggs and tomatoes, I got myself a second playground ;-) . As the title implies this series adds basic support for Rockchip's Cortex-A9 SoCs, like the RK3066 used in many cheaper tablets. On the periphal side it's very lightweight, as it seems someone from Rockchip was shopping in the DesignWare store. This makes the pinctrl driver the biggest hunk in the series, but to get some bonus points I used the generic_irq implementation for the interrupt handling, based on Thomas' irqdomain support series. Supported periphals are, the timers, uarts and mmc controllers, so interested parties will need a serial console for now. Hopefully I didn't mess up to much :-) Dependencies: - the irqdomain support for the generic_irq from Thomas Gleixner is required by the pinctrl driver - "mmc: dw_mmc: Add support DW SD/MMC driver on SOCFPGA" moves the SDMMC_CMD_USE_HOLD_REG constant into the common header, which is required on these Rockchip SoCs Heiko Stuebner (10): clocksource: dw_apb_timer_of: use the clocksource as sched clock if necessary clocksource: dw_apb_timer_of: add clock-handling clk: flag to use upper half of the register as change indicator clk: divider: add flag to limit possible dividers to even numbers mmc: dw_mmc-pltfm: remove static from dw_mci_pltfm_remove mmc: dw_mmc-pltfm: add Rockchip variant pinctrl: add pinctrl driver for Rockchip SoCs clk: add basic Rockchip rk3066a clock support arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: add basic support for Rockchip RK3066a boards .../bindings/pinctrl/rockchip-pinctrl.txt | 100 ++ Documentation/devicetree/bindings/rtc/dw-apb.txt | 19 + arch/arm/Kconfig | 2 + arch/arm/Kconfig.debug | 34 + arch/arm/Makefile | 1 + arch/arm/boot/dts/rk3066a-clocks.dtsi | 459 +++++++ arch/arm/boot/dts/rk3066a.dtsi | 359 ++++++ arch/arm/include/debug/rockchip.S | 42 + arch/arm/mach-rockchip/Kconfig | 17 + arch/arm/mach-rockchip/Makefile | 1 + arch/arm/mach-rockchip/Makefile.boot | 3 + arch/arm/mach-rockchip/rockchip.c | 54 + drivers/clk/Makefile | 1 + drivers/clk/clk-divider.c | 29 +- drivers/clk/clk-gate.c | 24 +- drivers/clk/clk-mux.c | 15 +- drivers/clk/rockchip/Makefile | 6 + drivers/clk/rockchip/clk-rockchip-pll.c | 131 ++ drivers/clk/rockchip/clk-rockchip-pll.h | 19 + drivers/clk/rockchip/clk-rockchip.c | 315 +++++ drivers/clocksource/dw_apb_timer_of.c | 52 +- drivers/mmc/host/dw_mmc-pltfm.c | 48 +- drivers/pinctrl/Kconfig | 6 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-rockchip.c | 1319 ++++++++++++++++++++ include/dt-bindings/pinctrl/rockchip.h | 37 + include/linux/clk-provider.h | 18 + include/linux/clk/rockchip.h | 21 + 28 files changed, 3097 insertions(+), 36 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/rockchip-pinctrl.txt create mode 100644 arch/arm/boot/dts/rk3066a-clocks.dtsi create mode 100644 arch/arm/boot/dts/rk3066a.dtsi create mode 100644 arch/arm/include/debug/rockchip.S create mode 100644 arch/arm/mach-rockchip/Kconfig create mode 100644 arch/arm/mach-rockchip/Makefile create mode 100644 arch/arm/mach-rockchip/Makefile.boot create mode 100644 arch/arm/mach-rockchip/rockchip.c create mode 100644 drivers/clk/rockchip/Makefile create mode 100644 drivers/clk/rockchip/clk-rockchip-pll.c create mode 100644 drivers/clk/rockchip/clk-rockchip-pll.h create mode 100644 drivers/clk/rockchip/clk-rockchip.c create mode 100644 drivers/pinctrl/pinctrl-rockchip.c create mode 100644 include/dt-bindings/pinctrl/rockchip.h create mode 100644 include/linux/clk/rockchip.h -- 1.7.2.3
