This is the second version of RFC patchset for Allwinner ARMv5 F1C100s
SoC. Icenowy (author of the initial patchset) allowed me to continue.
For patch 1~3 which introduces first ARMv5 Allwinner SoC I looked
freescale,imx configs and tried to organize patches better.
Addressed comment from Maxime Ripard and added SoC name to
compatibles and filenames.
Addressed comment from Rob Herring and added dt-bindings.
This is my first patch. Sorry for any inconvenience :-)
Original cover later:
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.
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

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

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.

There's no need to define the pattern, just list the compatibles
supported. Otherwise, you give the idea that all the combinations are
supported, and they aren't.

You don't really need that type. It's completely redundant with the
compatible.

Ideally, this should be a structure so that we can easily extend it
without adding more and more global variables. And the type shouldn't
be signed.

Letters come after the numbers in alphabetical order, so that should
be moved at the end of that list (and you have that issue in a couple
of other patches).

If SUN4I_TIMER is needed both by the armv5 and armv7 cores, why did we
need to move it out of ARCH_SUNXI?

I would drop the "new" here.

Do we really need a separate file for that?

Apart from the minor comments you'll find with each patches, you did
great :)

This one should be squashed in the previous patch.

You should have a compatible for that SoC there (possibly keeping the
A10 compatible if that makes sense).

Sorry, but old F-series SoCs are not suniv. They are sunii or sun3i.
