[PATCH v2 0/8] 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/.

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
