Allwinner also has some ARMv5 SoCs.
In order to add support for them, add a CONFIG_ARCH_SUNXI_V7 option that
is selectable when ARMv7 is selceted, and make CONFIG_ARCH_SUNXI a
common bool config which is selected by both V7 and V5 sunxi option.
The ARMv7 defconfigs are modified to have the new CONFIG_ARCH_SUNXI_V7
option.

Shouldn't you remove all the common ARCH_SUNXI selects from ARCH_SUNXI_v7?

The new F-series SoCs (suniv) from Allwinner use an stripped version of
the interrupt controller in A10/A13.
Add support for it in irq-sun4i driver.

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 (newer F-series Allwinner SoCs) is based on ARM926EJ-S
CPU, thus it has no architecture timer.
Register sun4i_timer as sched_clock on it.

The suniv 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.

As we have the support for suniv pin controller and CCU now, add a
initial DTSI for it.
F1C100s is one product with the suniv die, which has a 32MiB co-packaged
DDR1 DRAM chip. As there's nothing special for it, add a dummy DTSI file
for it.

The hunk above should go with your patch
"[RFC PATCH 9/9] ARM: suniv: f1c100s: add device tree for Lichee Pi Nano"

Lichee Pi Nano is a F1C100s board by Lichee Pi.
Add initial device tree for it.

Where is that suniv prefix coming from?
And you need to have a SoC in all your compatibles. This isn't about
being clever or not, this is just a matter of being able to accurately
read in a crystal ball. Or maybe it's just the same, in which case,
I'd really like to have a course :)
You should really answer two questions here:
- Are you able to predict whether you'll find an SoC part of that
family in the future that derives a bit and will need a compatible
of its own?
- Are you able to predict which quirks we'll need along the way to
support all the SoCs you've listed there?
If you can't answer yes to both these questions, with a 100%
certainty, then you'll need a SoC name in the compatible.
Which doesn't prevent you from sharing as much as possible the DT like
we did between the A10s and the A13 for example.
