Pull clk updates from Michael Turquette:
"The clk framework changes for 4.3 are mostly updates to existing
drivers and the addition of new clock drivers. Stephen Boyd has also
done a lot of subsystem-wide driver clean-ups (thanks!). There are
also fixes to the framework core and changes to better split clock
provider drivers from clock consumer drivers"

We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

Release all blocks after the pipe is disabled, even when vsync
didn't happen in some error cases. Allow requesting SMB multiple
times before configuring to hardware, by releasing blocks not
programmed to hardware yet for shrinking case.
This fixes a potential leak of shared memory pool blocks.

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

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.

The current iteration in get_dsi_id_from_intf() is wrong:
instead of iterating until hw_cfg->intf.count, we need to iterate
until MDP5_INTF_NUM_MAX here.
Let's take the example of msm8x16:
hw_cfg->intf.count = 1
intfs[0] = INTF_Disabled
intfs[1] = INTF_DSI
If we stop iterating once i reaches hw_cfg->intf.count (== 1),
we will miss the test for intfs[1].
Actually, this hw_cfg->intf.count entry is quite confusing and is not
(or *should not be*) used anywhere else; let's remove it.

The DRM_KMS_FB_HELPER config is selected only when DRM_MSM_FBDEV config is

support is disabled in msm. Wrap around these functions with #ifdef checks to
prevent build break.
