Original commit messages:
**
video: tegra: dc: use nvhost driver for host1x power management
Incrementing the frame done syncpoint value from the display interrupt
requires that the host module is powered on. As the syncpoint state is
saved and restored automatically by the host driver a cpu increment of
a syncpoint in the powered down state will be lost.
Also adds checks for host module being powered.
**
video: tegra: fb: add ioctl to flip dc windows to nvmap handles
tegra user-space graphics drivers may allocate framebuffers using
nvmap rather than rendering to the common framebuffer, this may
be done to support deeper buffer pipelining, color formats
and pixel layouts other than the initial bootup framebuffer,
etc.
to use this ioctl, a caller must first specify an nvmap fd
which is already open in the calling process so that the
subsequent flip ioctls may be properly validated. flips are performed
asynchronously, with flip completion notifications provided back to
the caller via the host1x syncpoint mechanism
based on earlier changes made by Antti Hatala <ahatala@nvidia.com>
and Erik Gilling <konkers@android.com>

Notable ommisions:
* support for anything but lvds panels
* inegration with nvhost driver to sync updates with 3D
* FB physical geometry is not set
* lacks interface to set overlay/window x,y offset
v2 changes:
* suspend/resume support
* move code into drivers/video/tegra/dc
* modularize output support
* clean register dumping, add debugfs register file
* code review feedback
* make the display controller register the framebuffer devices
