This is a collection of a few late fixes and other misc. stuff that
had dependencies on things being merged from other trees.
The Renesas R-Car power domain handling, and the Nvidia Tegra USB
support both hand notable changes that required changing the DT binding
in a way that only provides compatibility with old DT blobs on new
kernels but not vice versa. As a consequence, the DT changes
are based on top of the driver changes and are now in this branch.
For NXP i.MX and Samsung Exynos, the changes in here depend on
other changes that got merged through the clk maintainer tree.

Use the new SoC specific binding for rcar-dmac and the generic
binding as a fall-back in the r8a7794 device tree.
In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compat strings has been adopted.
Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car DMA Controller nodes to follow this convention.

Replace the "arm,cortex-a15-gic" compatible value for the GIC by

This has been confirmed by reading the GICD_IIDR register (on r8a7791),
which reports 0x0200043b (GIC-400 = 0x02, ARM = 0x43b).
This has no effect on runtime behavior, as currently the GIC driver
