Thomas Hellstrom 4e0858a682 drm/vmwgfx: Properly flush cursor updates and page-flips
With the introduction of the new command buffer mechanism,
proper care wasn't taken to flush cursor image updates and
event-less screen-target page-flips.

Fix this by introducing explicit flush points.

Dan Williams 5ad9dceee9 drm/vmwgfx: switch from ioremap_cache to memremap
Per commit 2e586a7e01 "drm/vmwgfx: Map the fifo as cached" the driver
expects the fifo registers to be cacheable.  In preparation for
deprecating ioremap_cache() convert its usage in vmwgfx to memremap().

Few more drm-misc stragglers for 4.4. Big thing is the generic probe for
imx/rockchip/armada (but the variant for msm/rpi/exynos is still missing).

Also the hdmi clocking fixes from Ville which was a lot of confusion about
which tree it should be applied to ;-)

Dave Airlie d7e1bc3f5e Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
A bit smaller pull this time.  Few minor things, plus initial support
for msm8996 (snapdragon 820)..  Sorry, a bit latish, was hoping to get
some 8960/8064 DSI stuff included.  But still waiting on the v2 of the
patchset (just pending some minor review comments).  It would be nice
to get the DSI patches merged since it would help some folks trying to
get upstream kernel running on n4/n7 and xperia z and wanting to write
some more panel drivers.  Also, waiting for OCMEM driver to get merged
via other trees and then I have a small bit to go along with that to
make the gpu actually work on devices w/ OCMEM (snapdragon 800, 805,
etc).  So maybe a second later pull req, time permitting.

Stephane Viau 8e2930c6cf drm/msm/mdp: Add Software Pixel Extension support
In order to produce an image, the scalar needs to be fed extra
pixels. These top/bottom/left/right values depend on a various of
factors, including resolution, scaling type, phase step and
initial phase.

Pixel Extension are programmed by hardware in most targets - and
can be overwritten by software. For some targets (e.g.: msm8996),
software *must* program those registers.

In order to ease this computation, let's always use bilinear
filters, which are easier to program from kernel. Eventually,
all of these values will come down from user space for better
quality.

Stephane Viau d40325b437 drm/msm/mdp5: Avoid printing error messages for optional clocks
The current behavior is to try to get optional clocks and print a
dev_err message in case of failure. This looks rather confusing
and may increase with the amount of optional clocks.

We may need a cleaner way to handle per-device clocks but in the
meantime, let's reduce the amount of dev_err messages during the
probe.

This is enough for fbcon and bringing up X using
xf86-video-modesetting.  It doesn't support the 3D accelerator or

v2: Drop FB_HELPER select thanks to Archit's patches.  Do manual init

    more like tegra's, but still using the typical "component" code.
    Drop no-op hooks for atomic_begin and mode_fixup() now that
    they're optional.  Drop sentinel in Makefile.  Fix minor style
    nits I noticed on another reread.

v3: Use the new bcm2835 clk driver to manage pixel/HSM clocks instead
    of having a fixed video mode.  Use exynos-style component driver
    matching instead of devicetree nodes to list the component driver
    instances.  Rename compatibility strings to say bcm2835, and
    distinguish pv0/1/2.  Clean up some h/vsync code, and add in
    interlaced mode setup.  Fix up probe/bind error paths.  Use
    bitops.h macros for vc4_regs.h

v4: Include i2c.h, allow building under COMPILE_TEST, drop msleep now

Liviu Dudau 7fc7e86d09 drm/armada: Convert the probe function to the generic drm_of_component_probe()
The armada DRM driver keeps some old platform data compatibility in the
probe function that makes moving to the generic drm_of_component_probe()
a bit more complicated that it should. Refactor the probe function to do
the platform_data processing after the generic probe (and only if that
fails). This way future cleanup can further remove support for it.

Liviu Dudau 9cace32f7e drm/imx: Convert the probe function to the generic drm_of_component_probe()
The generic function is functionally equivalent to the driver's
imx_drm_platform_probe(). Use the generic function and reduce the
overall code size.

Liviu Dudau df785aa87f drm: Introduce generic probe function for component based masters.
A lot of component based DRM drivers use a variant of the same code
as the probe function. They bind the crtc ports in the first iteration
and then scan through the child nodes and bind the encoders attached
to the remote endpoints. Factor the common code into a separate
function called drm_of_component_probe() in order to increase code
reuse.

Ville Syrjälä 9afd808cf3 drm/edid: Round to closest when computing the CEA/HDMI alternate clock
Rounding to the closest kHz seems like the better option that round
down or up when computing the alternate clock for CEA/HDMI modes.
It'll give us a slightly more accurate clock in some cases.

Not sure why I went for the down+up approach originally. Perhaps
I was thinking we can go back and forth betwen the two frequencies
without introducing errors, but round to closest still maintains
that property.
