Subject[PATCH v2 0/3] irqchip: vf610-mscm: add support for MSCM interrupt router
Date
Splitted out version of the MSCM driver. My first driver based on the
routeable domain support and was part of the Vybrid Cortex-M4 support
patchset.

So far the MSCM interrupt router was initialized by the boot loader
and configured all interrupts for the Cortex-A5 CPU. There are two
use cases where a proper driver is necessary:
- To run Linux on the Cortex-M4. When the kernel is running on the
non-preconfigured CPU, the interrupt router need to be configured
properly.
- To support deeper sleep modes: LPSTOP clears the interrupt router
configuration, hence a driver needs to restore the configuration
on resume.
I created a seperate patchset for that driver which hopefully makes
it easier to get it into mergeable state.

The patchset is based on the master branch of Linus with the branch
irq-irqdomain-arm-for-linus from tip merged. I guess this will apply
flawless on 3.19-rc1 once it's out.

Changes since v1 (part of Vybrid Cortex-M4 support)
- Rewrite with irqdomain hierarchy
- Implemented as proper irqchip and move to driver/irqchip/
- Doesn't work on Cortex-M4 anymore (NVIC as parent is not yet
implemented)
