This patch resolves temporarily infinite loop issue incurred
when Exynos drm driver is enabled and multi-platform kernel
is used by registering Exynos drm device object only in case
of Exynos SoC. So this patch will be replaced with more generic
way later.

This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.

This patch adds non-continuous clock mode support
Clock mode on Clock Lane is continuous clock by default.
So if we want to transmit data in non-continuous clock mode
to reduce power consumption, then host driver should set
DSIM_CLKLANE_STOP bit. In this case, host controller turns off
HS clock between high speed transmissions.
For this, this patch adds a new bit, DSIM_CLKLANE_STOP, and makes
the host driver sets this bit only in case that dsi->mode_flags has
MIPI_DSI_CLOCK_NON_CONTINUOUS flag.

One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

This pull is missing nouveau, Ben has been stuck trying to track down
a very longstanding bug that revealed itself due to some other

once he cleans things up. I'm away until Monday so don't want to
delay things, you can make a decision on that when he sends it, I have
my phone so I can ack things just not really merge much.
It has one trivial conflict with your tree in armada_drv.c, and also
the pull request contains some component changes that are already in
your tree, the base tree from Russell went via Greg's tree already,
but some stuff still shows up in here that doesn't when I merge my
