The imx-drm driver was put into staging mostly for the following reasons,
all of which have been addressed or superseded:
- convert the irq driver to use linear irq domains
- work out the device tree bindings, this lead to the common of_graph
bindings being used
- factor out common helper functions, this mostly resulted in the
component framework and drm of_graph helpers.
Before adding new fixes, and certainly before adding new features,
move it into its proper place below drivers/gpu/drm.

usb: patches for v3.19 merge window
This time, a very pull request with 216 non-merge
commits. Most of the commits contained here are
sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.
More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().
DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.
DWC3 got support for two new HW platforms: Exynos7
and AMD.
The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.
Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).
Other than these, the usual set of cleanups and
non-critical fixes.
