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
