v3 cover ARM: Conexant Digicolor CX92755 SoC support

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/.

v3:
* Remove earlyprintk from dts bootargs (Arnd Bergmann)

* Move aliases from chip .dtsi to board .dts (Arnd Bergmann)

* Add 'cpus' node (Mark Rutland)

* Add commit log messages to all patches (Arnd Bergmann)

* Add Arnd's ack

* Split arch/arm stuff from the irq and timer drivers

v2:
http://marc.info/?t=142074613900007&r=1&w=2

* 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

v1:

I think we should use the actual SoC name, that is cx92755, just like the .dtsi file is named. I'll resend this patch with the name change and a few more incremental changes needed by the interrupt controller and timer drivers.

Hi ARM SoC maintainers,

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/.

Any chance of having this series merged for 3.20? Arnd has acked this already.

Thanks,

Hi ARM SoC maintainers,
Quoted 6 lines · Baruch Siach
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/.
Any chance of having this series merged for 3.20? Arnd has acked this already.

Yep, just had a small comment on naming for the third patch, the rest have been applied now.
