Commit eb10d6355532 ("imx-drm: encoder prepare/mode_set must use adjusted mode")
broke the first LVDS modeset by using crtc->hwmode before crtc mode_set is
called. In fact, encoder prepare is not supposed to prepare the display clock
at all. Rather encoder mode_set should be used to set the DI clock rate, before
it is enabled by crtc commit.Reported-by: Liu Ying

Pull staging driver updates from Greg KH:
"Here's the big staging tree pull request for 3.19-rc1.We continued to delete more lines than were added, always a good
thing, but not at a huge rate this release, only about 70k lines
removed overall mostly from removing the horrid bcm driver.Lots of normal staging driver cleanups and fixes all over the place,
well over a thousand of them, the shortlog shows all the horrid
details.The "contentious" thing here is the movement of the Android binder
code out of staging into the "real" part of the kernel. This is code
that has been stable for a few years now and is working as-is in the
tens of millions of devices with no issues. Yes, the code is horrid,
and the userspace api leaves a lot to be desired, but it's not going
to change due to legacy issues that we have no control over. Because
so many devices and companies rely on this, and the code is stable,
might as well promote it out of staging.This was all discussed at the Linux Plumbers conference, and everyone
participating agreed that this was the best way forward.There is work happening to replace the binder code with something new
that is happening right now, but I don't expect to see the results of
that work for another year at the earliest. If that ever happens, and
Android switches over to it, I'll gladly remove this version.As for maintainers, I'll be glad to maintain this code, I've been
doing it for the past few years with no problems. I'll send a
MAINTAINERS entry for it before 3.19-final is out, still need to talk
to the Google developers about if they are willing to help with it or
not, last I checked they were, which was good.All of these patches have been in linux-next for a while with no
reported issues"* tag 'staging-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1382 commits)

Pull drm updates from Dave Airlie:
"Highlights:- AMD KFD driver merge
This is the AMD HSA interface for exposing a lowlevel interface for
GPGPU use. They have an open source userspace built on top of this
interface, and the code looks as good as it was going to get out of
tree.- Initial atomic modesetting work
The need for an atomic modesetting interface to allow userspace to
try and send a complete set of modesetting state to the driver has
arisen, and been suffering from neglect this past year. No more,
the start of the common code and changes for msm driver to use it
are in this tree. Ongoing work to get the userspace ioctl finished
and the code clean will probably wait until next kernel.- DisplayID 1.3 and tiled monitor exposed to userspace.
Tiled monitor property is now exposed for userspace to make use of.

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.Signed-off-by: Philipp Zabel
