e43f2c3395 drm/omap: fix primary-plane's possible_crtcs
We set the possible_crtc for all planes to "(1 << priv->num_crtcs) - 1",
which is fine as the HW planes can be used fro all crtcs. However, when
we're doing that, we are still incrementing 'num_crtcs', and we'll end
up with bad possible_crtcs, preventing the use of the primary planes.

This patch passes a possible_crtcs mask to plane init function so that
we get correct possible_crtc.

5cd57a46e3 drm: fix possible_crtc's type
drm_universal_plane_init() and drm_plane_init() take "unsigned long
possible_crtcs" parameter, but then stuff it into uint32_t. Change the
parameter to uint32_t.

45d59d7040 drm: Add new driver for MXSFB controller
Add new driver for the MXSFB controller found in i.MX23/28/6SX .
The MXSFB controller is a simple framebuffer controller with one
parallel LCD output. Unlike the MXSFB fbdev driver that is used
on these systems now, this driver uses the DRM/KMS framework.

4e77524926 drm/exynos: Use VIDEO_SAMSUNG_EXYNOS_GSC=n as GSC Kconfig dependency
Commit aeefb36832 ("drm/exynos: gsc: add device tree support and remove
usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only
be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use
the same HW IP block.

But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is
not correct since Kconfig expressions are not boolean but tristate. So it
will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate
to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m.

This means that both the V4L2 and DRM drivers can be enabled if the former
is enabled as a module, which isn't what we want since otherwise 2 drivers
could attempt to use the hardware at the same time.

1db0127904 drm/etnaviv: move linear window on MC1.0 parts if necessary
On i.MX6SX the physical memory is placed above the 2GB mark, so the GPU
linear window has to be moved for the GPU to work at all. This doesn't
mix with the FAST_CLEAR feature, as the TS unit doesn't take the linear
window offset into account and will corrupt memory when used with a
non-zero offset.

Move the linear window if it's necessary for the GPU to work, but avoid
announcing FAST_CLEAR support to userspace in this case.

f559013436 Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
On the userspace side, all the basics are working, and most of glmark2
is working.  I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%).  I expect
to push the mesa patches today or tomorrow.

There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree.  If that can land in the next day or two, there might
be a second late pull request for drm/msm.

In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step.  All those patches should also help
out atomic weston (when those patches eventually land).

9345235e9c drm/tilcdc: implement palette loading for rev1
Revision 1 of the IP doesn't work if we don't load the palette (even
if it's not used, which is the case for the RGB565 format).

Add a function called from tilcdc_crtc_enable() which performs all
required actions if we're dealing with a rev1 chip.

ec9eab097a drm/tilcdc: Add drm bridge support for attaching drm bridge drivers
Adds drm bride support for attaching drm bridge drivers to tilcdc. The
decision whether a video port leads to an external encoder or bridge
is made simply based on remote device's compatible string. The code
has been tested with BeagleBone-Black with and without BeagleBone
DVI-D Cape Rev A3 using ti-tfp410 driver.

dc55ac3b52 drm/bridge: Add ti-tfp410 DVI transmitter driver
Add very basic ti-tfp410 DVI transmitter driver. The only feature
separating this from a completely dummy bridge is the EDID read
support trough DDC I2C. Even that functionality should be in a
separate generic connector driver. However, because of missing DRM
infrastructure support the connector is implemented within the bridge
driver. Some tfp410 HW specific features may be added later if needed,
because there is a set of registers behind i2c if it is connected.

This implementation is tested against my new tilcdc bridge support
and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document
is also updated.

13b3d72705 drm/tilcdc: Recover from sync lost error flood by resetting the LCDC
Recover from sync lost error flood by resetting the LCDC instead of
turning off the SYNC_LOST error IRQ. When LCDC starves on limited
memory bandwidth it may sometimes result an error situation when the
picture may have shifted couple of pixels to right and SYNC_LOST
interrupt is generated on every frame. LCDC main reset recovers from
this situation and causes a brief blanking on the screen.
