[RFC,v4,00/17] initial support for "suniv" Allwinner new ARM9 SoC

This is the fourth version of RFC patchset for Allwinner ARMv5 F1C100s
SoC. Addressed comments from Maxime Ripard, added Acked-by signatures.

Changes since v3:
- Patch "ARM: Check ARCH_MULTI_V7 to differentiate ARMv5/v7 Allwinner SoCs"
  - Remove CONFIG_ARCH_SUNXI_Vx. Use ARCH_MULTI_Vx to differentiate SoC's
  - Change KConfig ARCH_SUNXI selection: 'select' to 'default'. 
- Patch "irqchip/sun4i: Add a struct to hold global variables"
  - Split irq_sun4i.c changes to 3 patch.
- Patch "pinctrl: sunxi: add support for suniv F1C100s (newer F-series SoCs)"
  - pinctrl-suniv-f1c100s: remove: disable_strict_mode = true
- Patch "ARM: dts: suniv: add initial DTSI file for F1C100s"
  - suniv-f1c100s.dtsi: remove unnecessary componenets.
  - Instead of patching drivers, add original compatible string with 
f1c100s compatibles.
  - Add Acked-by signatures.

Changes since v2:
- Patch "ARM: sunxi: add Allwinner ARMv5 SoCs"
  - Move SUN4I_TIMER option to ARCH_SUNXI
  - Added help text for MACH_SUNIV
- Patch "irqchip/sun4i: add support for suniv interrupt controller"
  - Defined sunxi_irq_chip_data struct and used it to differentiate
    registers between different chips.
- Patch " ARM: dts: suniv: add initial DTSI file for F1C100s"
  - Removed unnecessary fake clock.
  - Fixed compatible strings.

Changes since v1:
- Patch "ARM: add CONFIG_ARCH_SUNXI_V7 for differentiate ARMv5/v7
  Allwinner SoCs"
  - Instead of using a common bool config use a common menuconfig. 
  - Use ARCH_MULTI_V7 to differentiate V7 SoCs.
  - Addressed comment from Julian Calaby
- Patch "ARM: sunxi: add Allwinner ARMv5 SoCs"
  - Use ARCH_MULTI_V5 to differentiate V5 SoCs.
  - removed "allwinner,suniv" board compatible string
  - Added dt-bindings
- Patch "irqchip/sun4i: add support for suniv interrupt controller"
  - Added dt-bindings
  - Changed "allwinner,suniv-ic" to "allwinner,suniv-f1c100s-ic"
- Patch "clocksource: sun4i: add a compatible for suniv"
  - Added dt-bindings
  - Changed "allwinner,suniv-timer" to "allwinner,suniv-f1c100s-timer"
- Patch "pinctrl: sunxi: add support for suniv F1C100s (newer F-series SoCs)"
  - Added dt-bindings
  - Renamed suniv-pinctrl to suniv-f1c100s-pinctrl
- Patch "clk: sunxi-ng: add support for suniv F1C100s SoC"
  - Added dt-bindings
  - Renamed suniv-ccu to suniv-f1c100s-ccu
- Patch "ARM: suniv: f1c100s: add device tree for Lichee Pi Nano"
  - Addressed comment from Rask Ingemann Lambertsen

Thanks!
