The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.
Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

This moves the set-up of the HREF500 with its AB8505 ASIC to

This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

Cleaning up that code touches multiple subsystems, but gets rid

If we attempt to use the existing u8500 of_dev_auxdata struct to boot
the u8540, we fail to obtain a console, due to a lack of DMA support
on the platform.

It was required to pass DMA channel configuration information to the
UART driver before the new DMA API was in place. Now that it is, and
is fully compatible with Device Tree we can stop doing that.

Ironically, in order to remove lots of the auxdata assignments, we have
to add just one more. A lot of them require DMA information to be passed
into clients for DMA channel allocation, but we now have this capability
in Device Tree. However, the DMA40 driver still relies on a reverse table
look-up to obtain DMA addresses. Until all of the clients are converted,
over to the new API, we're stuck with this.
Also, now the DMA40 has been DT:ed, there's no requirement to register
it using traditional methods, so let's remove it.
