This patch implements generic DT L2C initialisation (the one from
init_IRQ in arch/arm/kernel/irq.c) for Omap4 and AM43 platforms and
kills the SoC specific stuff in arch/arm/mach-omap2/omap4-common.c.

I did it right: https://lkml.org/lkml/2014/12/23/158
Please test, because I have no access to Omap hardware.
Best regards

really like to have something merged. The
discussion about iommu controllers lasts for about 2 years and we still
don't
have ANYTHING working in mainline, so lets merge the of_iommu glue and then
check how the remaining issues can be solved.

Hello Everyone,
This is another attempt to finally make Exynos SYSMMU driver fully

TV Mixer needs both TV and LCD0 domains enabled to be fully operational.
This dependency is modelled by making TV power domains a sub-domain of
LCD0 power domain.

This patch adds support for making one power domain a sub-domain of
other domain. This is useful for modeling power dependences for devices
like TV Mixer or Camera ISP, which needs to have more than one power
domain enabled to be operational.

This is an updated patchset, which intends to add support for L2 cache

This patch adds mutex, which protects initialization and
deinitialization procedures against suspend/resume methods. This mutex
will be needed by the updated suspend/resume calls, which tracks gadget
state.

Suspend/resume code assumed that the gadget was always started and
enabled to connect to usb bus. This means that the actual state of the
gadget (started/stopped or connected/disconnected) was not correctly
preserved on suspend/resume cycle. This patch fixes this issue.

This patch renames some variables to make the code easier to understand.
'domain' is replaced by 'iommu_domain' (more generic entity) and really
meaning less 'priv' by 'domain' to reflect its purpose.
