This series adds initial support for the Conexant CX92755 SoC. The CX92755 is
one of the Digicolor series of SoCs, all sharing many of the same peripherals.
The code was tested on the CX92755 evaluation kit, AKA Equinox.
Uses attempting to try this code will most likely also want the UART/console
driver available from https://patchwork.kernel.org/patch/5515861/.
v2:
* Remove .map_io assignment, debug_ll is enabled by default (Arnd Bergmann)
* Migrate the irq driver to generic irq chip, simplifying the code somewhat
(Arnd Bergmann)
* Change the timer dt binding, so that the 'reg' property points to the
first "Agent Communication" register. This should improve the chance of
reusing this binding for other SoCs in this series.
* Add the CONTROL() and COUNT() macros to the timer driver to make the code
clearer.
* Move arch/arm Kconfig changes from the clocksource driver patch to the
base arch support patch to reduce dependency between them

Please don't put earlyprintk into the dtb. Hopefully by the next
merge window we will have working earlycon support as a replacement.
You can already put an stdout-path property into the chosen node
for this.

Looks great overall now.
I have just two more comments in one patch, and one general request:
Please add a patch description for every patch. The text above would
be a good start for the first patch, but it would be lost in the git

patches to arm@kernel.org, and send the other patches as separate

I didn't spot "cnxt" in
Documentation/devicetree/bindings/vendor-prefixes.txt in mainline, nor
did I spot it added as part of this series. Please add it, assuming a
patch doing so is not already queued elsewhere.

There is no configuration that can be applied to individual interrupt

I didn't spot "cnxt" in
Documentation/devicetree/bindings/vendor-prefixes.txt in mainline, nor
did I spot it added as part of this series. Please add it, assuming a
patch doing so is not already queued elsewhere.

There is no configuration that can be applied to individual interrupt

The node name should be "interrupt-controller@f0000000", according to the

I sent a vendor-prefixes.txt update earlier as part of the UART driver series.
Greg has it queued in the tty-testing branch of his tty tree
(https://git.kernel.org/cgit/linux/kernel/git/gregkh/tty.git/commit/?h=tty-testing&id=48c738631753186e0ec7dd0079beffb3a6f4bb5c).

Yes. The interrupt controller uses just a small area in this registers space
(offsets 0x40 - 0x80). This trouble is that I also need access to the system
global UC_IRQ_CONTROL register (offset 0x3a4), to configure interrupts channel
and routing (IRQ/FIQ). I wonder whether register access via syscon is better.

What about the last patch in this series (ARM: devicetree: document supported
Conexant Digicolor SoC)? What tree should it go through.

That can go along with the first three patches for the platform.

I found this message while looking into CONFIG_ARCH_DIGICOLOR. That
Kconfig macro entered linux-next in next-20150128. But there's no
Kconfig symbol ARCH_DIGICOLOR yet in linux-next.
As you might be aware I try to check each linux-next release for Kconfig
oddities. One of the oddities I tend _not_ to report are things like
this. That is, SoC's, MFD's, or whatever, were specific drivers can get
merged before the core functionality. In this case the irqchip driver
got merged into linux-next while the core ARCH_DIGICOLOR code is still
pending. And you happen to be involved with quite a bit of code in areas
like that.
Pre-merges like this appear unavoidable (ie, other workflows would be
more trouble for the people involved). But what would be a good moment
to still raise an issue like this? Just to make sure things don't fall
through the cracks. As in: "this driver got merged into mainline but do
you know you can't yet build it?". Perhaps with each -rc1?

Just for the record: base digicolor platform support is in the for-next branch
of arm-soc.git since today. I guess it should appear in linux-next tomorrow.

So I choose a less convincing patch series to discuss this. But that
doesn't alter the general issue I raised. At least, I hope it doesn't.
