We use the same check already in the atomic core, so might as well
make this official. And it's also reused in e.g. i915.
Motivated by Maarten's idea to extract a connector_changed state out
of mode_changed.

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

Track the list of in-flight submits. If the gpu hangs, retire up to an
including the offending submit, and then re-submit the remainder. This
way, for concurrently running piglit tests (for example), one failing
test doesn't cause unrelated tests to fail simply because it's submit
was queued up after one that triggered a hang.

The 'timeout' value comes from userspace (CLOCK_MONOTONIC), but
converting this directly to jiffies doesn't take into account the
initial jiffies count at boot, which may differ from the base time
of CLOCK_MONOTONIC.
TODO: add ktime_delta_jiffies() when rebasing on 4.1 and use that
instead of ktime_sub/ktime_to_timespec/timespec_to_jiffies combo (as
suggested by Arnd)
v2: switch over from 'struct timespec' to ktime_t throughout, since
'struct timespec' will be deprecated (as suggested by Arnd)
v3: minor cosmetic tweaks

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.

There are different types of PHY from one chipset to another, while
the DSI host controller is relatively consistent across platforms.
Also, the PLL inside PHY is providing the source of DSI byte and
pixel clocks, which are used by DSI host controller. Separated devices

MDP FLUSH registers could indicate if the previous flush updates
has taken effect at vsync boundary. Making use of this H/W feature
can catch the vsync that happened between CRTC atomic_flush and
*_wait_for_vblanks, to avoid unnecessary wait.
This change allows kms CRTCs to use their own *_wait_for_commit_done
functions to wait for FLUSH register cleared at vsync, before commit
completion.

Some DSI peripherals rely on the HS clock on DSI clock lane as their clock
source. If the clock lane transitions between HS and LP states, it
can disrupt the functioning of such peripherals.

such peripheral drivers. Use it to configure the bit CLKLN_HS_FORCE_REQUEST

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
knows the details of the driver.

wait_for_completion_timeout return >= 0 but never negative so the check
logic looks inconsistent. Further the return value of
wait_for_completion_timeout was being passed up the call chain but the
x call sites as drm_dp_i2c_do_msg()/drm_dp_dpcd_access() check for < 0
thus timeout was being treated as success case.
<snip> drivers/gpu/drm/drm_dp_helper.c:drm_dp_i2c_do_msg()
mutex_lock(&aux->hw_mutex);
ret = aux->transfer(aux, msg);
mutex_unlock(&aux->hw_mutex);
if (ret < 0) {
<snip>
logic in edp_aux_transfer() seems incorrect as it could return 0 (timeout)
but checks of <= 0 to indicate error so the return probably should be
-ETIMEDOUT in case wait_for_completion_timeout returns 0 (timeout
occurred).

Dump a bit more info when the GPU hangs, without having hang_debug
enabled (which dumps a *lot* of registers). Also dump the scratch
registers, as they are useful for determining where in the cmdstream
the GPU hung (and they seem always safe to read when GPU has hung).
Note that the freedreno gallium driver emits increasing counter values
to SCRATCH6 (to identify tile #) and SCRATCH7 (to identify draw #), so
these two in particular can be used to "triangulate" where in the
cmdstream the GPU hung.
