Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next

Main pull req for 4.2.. I think there will be a secondary pull-req..
I'd like to land the hdcp support patches, since all the review
comments have been long since addressed, and they have been ready to
merge for a couple release cycles now other than the scm dependency
(which should be coming in through arm-soc tree for 4.2). So I am not
including them in this initial pull req to avoid merge ordering
issues.

Main highlights:

1) adreno a306 support (for apq8x16 and upcoming dragonboard 410c)
2) various dsi bits
3) various 64bit fixes (mostly warnings)
4) NV12MT support, pulled in via msm-next rather than drm-misc since
dependency on on regenerated envytools headers (but lgtm'd-by danvet)
5) random fixes and cleanups

drm/msm: use devm_gpiod_get_optional for optional reset gpio

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Also there is a variant to find optional gpios that returns NULL if
there is no gpio instead of -ENOENT.

Make use of both features to simplify the driver.

This makes error checking more strict because errors like -ENOSYS ("no
gpio support compiled in") or -EPROBE_DEFER ("gpio not ready yet") are
handled correctly now.

Furthermore this is one caller less that stops us making the flags
argument to gpiod_get*() mandatory.

drm/msm: fix HZ dependency of timeout

The timeout is passed as a constant which makes it HZ dependent because
jiffies are expected so it should be converted to jiffies. The actual
value is not clear from the code - my best guess is that this should be
300 milliseconds given that other timeouts are in milliseconds based on
looking at other drm drivers (e.g. exynos_drm_dsi.c:356 300ms,
tegra/dpaux.c:188 250ms) - this needs to be confirmed by someone who
