ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4
Add defconfig for Linux on Vybrid (vf610) on the secondary Cortex-
M4 CPU. The use of a XIP image has been tested which needs to be
loaded (e.g. using the custom m4boot loader) to the end of the
available RAM at address 0x8f000000. The Cortex-M4 has a code-alias
which makes sure that the instructions get fetched through the code
bus (alias starts at 0x00800000 => 0x80800000 in system address).
Hence, to get optimal performance, use 0x0f000000 as XIP_PHYS_ADDR.
This address is additionally shifted by the length of the minimal
loader which is inserted by m4boot. Currently, this offset is 0x80.
The standard DRAM base address is configured to 0x8C000000, which
gives the Cortex-M4 48MiB of RAM.

drm: Zero out invalid vblank timestamp in drm_update_vblank_count.
Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

ARM: dts: Make DP a consumer of DISP1 power domain on Exynos5420
Commit ea08de16eb1b ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.
This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.
Make the DP controller device node a consumer of the DISP1 power domain
to ensure that the PD is turned on when the exynos-dp driver is probed.

drm/tegra: Don't use vblank_disable_immediate on incapable driver.
Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().
Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.

drm/i915: Drop PIPE-A quirk for 945GSE HP Mini
Since the introduction of BIOS fb preservation, circa 3.17, we began
encountering a failure during boot when trying to use force-detect
before GEM was initialised. That bug is from
drm/i915: ensure the force pipe A quirk is actually followed
but investigation of the affected machine revealed that it was using a
PIPE-A quirk even though it was a 945GSE and the quirk is only supposed
to be used to workaround a hardware issue on 830/845. That quirk was
added for this HP Mini in
in order to workaround an issue with the BIOS behaving strangely during
lid-close. Since then we have a much larger hammer to thwart the BIOS
after opening the lid and the PIPE-A quirk is no longer required.
