    Subject[RFC PATCH 0/9] initial support for "suniv" Allwinner new ARM9 SoC
    Date
    This is the RFC initial patchset for the "new" Allwinner SUNIV ARM9 SoC.

    The same die is packaged differently, come with different co-packaged
    DRAM or shipped with different SDK; and then made many model names: F23,
    F25, F1C100A, F1C100S, F1C200S, F1C500, F1C600, R6, etc. These SoCs all
    share a common feature set and are packaged similarly (eLQFP128 for SoCs
    without co-packaged DRAM, QFN88 for with DRAM). As their's no
    functionality hidden on the QFN88 models (except DRAM interface not
    exported), it's not clever to differentiate them. So I will use suniv as
    common name of all these SoCs.

    As it's the first not ARMv7+ Allwinner SoC to get supported, this
    patchset firstly made CONFIG_ARCH_SUNXI a common config item, and let
    selectable CONFIG_ARCH_SUNXI_V{5,7} to internally select it. This makes
    reusing most work possible. This is PATCH 1~2.

    The ARM9 has neither GIC nor arch_timer, like the sun4i/5i Cortex-A8
    SoCs. So adapt the IRQ and timer driver used by sun4i/5i to support
    suniv. This is PATCH 3~5.

    Then it's the common way to support a new SoC -- pinctrl, CCU and
    initial DT.

    Icenowy Zheng (9):
    ARM: add CONFIG_ARCH_SUNXI_V7 for differentiate ARMv5/v7 Allwinner
    SoCs
    ARM: sunxi: add Allwinner ARMv5 SoCs
    irqchip/sun4i: add support for suniv interrupt controller
    clocksource: sun4i: add a compatible for suniv
    clocksource/drivers/sun4i: register as sched_clock on suniv
    pinctrl: sunxi: add support for suniv (newer F-series SoCs)
    clk: sunxi-ng: add support for suniv SoC
    ARM: dts: suniv: add initial DTSI file for suniv and F1C100s
    ARM: suniv: f1c100s: add device tree for Lichee Pi Nano
