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

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

[Mesih Kilinc]

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

[RFC PATCH v4 01/17] ARM: Check ARCH_MULTI_V7 to differentiate ARMv5/v7 Allwinner SoCs

[Mesih Kilinc]

Allwinner also has some ARMv5 SoCs.

In order to add support for them, check ARM_MULTI_V7 before enabling
ARMv7 SoC's. Add help text for ARCH_SUNXI menuconfig.

[RFC PATCH v4 09/17] clocksource: sun4i: add a compatible for suniv

[Mesih Kilinc]

The suniv (new F-series) chip has a timer with less functionality than
the A10 timer, e.g. it has only 3 channels.

Add a new compatible for it. As we didn't use the extra channels on A10
either now, the code needn't to be changed.

The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer.

Register sun4i_timer as sched_clock on it.

[RFC PATCH v4 13/17] clk: sunxi-ng: add support for suniv F1C100s SoC

[Mesih Kilinc]

The suniv F1C100s SoC (the chip in some new F-series products of
Allwinner)
has a CCU which seems to be a stripped version of the CCU in SoCs after
sun6i.

Add support for the CCU.

[RFC PATCH v4 16/17] ARM: dts: suniv: add initial DTSI file for F1C100s

[Mesih Kilinc]

F1C100s is one product with the suniv die, which has a 32MiB co-packaged
DDR1 DRAM chip. As we have the support for suniv pin controller and CCU now, add a
initial DTSI for it.

The dt bindings headers and those DT are going to be merged through
separate trees, so you can't use these defines yet. Please use the
actual numbers in the DT for now, and send a patch fixing this when
4.21-rc1 will be out.

This would be uart0_pe_pins: uart0-pe-pins.

Thanks!
