Fixes for v6.0
- Fix for inconsistent indenting in function msm_dsi_dphy_timing_calc_v3.
This fixes a smatch warning reported by kbot
- Fix to make eDP the first connector in the connected list. This was
mainly done to address a screen corruption issue we were seeing on
sc7280 boards which have eDP as the primary display. The corruption
itself is from usermode but we decided to fix it this way because
things work correct with the primary display as the first one for
usermode
- Fix to populate intf_cfg correctly before calling reset_intf_cfg().
Without this, the display pipeline is not torn down correctly for
writeback
- Specify the correct number of DSI regulators for SDM660. It should
have been 1 but 2 was mentioned
- Specify the correct number of DSI regulators for MSM8996. It should
have been 3 but 2 was mentioned
- Fix for removing DP_RECOVERED_CLOCK_OUT_EN bit for tps4 link training
for DP. This was causing link training failures and hence no display
for a specific DP to HDMI cable on chromebooks
- Fix probe-deferral crash in gpu devfreq
- Fix gpu debugfs deadlock

In the event that devm_devfreq_add_device() fails the device's qos freq
list is left referencing df->idle_freq and df->boost_freq. Attempting to
initialize devfreq again after a probe deferral will then cause invalid
memory accesses in dev_pm_qos_add_request().
Fix this by dropping the requests in the error path.

Therefore SCRAMBLING_DISABLE bit should not be set for tps4 to

measurement with minimal equipment for embedded applications purpose
and is not required to be set during normal operation. Current

To avoid preventing the display from coming up before the rootfs is
mounted, without resorting to packing fw in the initrd, the GPU has
this limbo state where the device is probed, but we aren't ready to
start sending commands to it. This is particularly problematic for
a6xx, since the GMU (which requires fw to be loaded) is the one that
is controlling the power/clk/icc votes.
So defer enabling runpm until we are ready to call gpu->hw_init(),
as that is a point where we know we have all the needed fw and are
ready to start sending commands to the coproc's.

Even if some IOMMU has registered itself on the platform "bus", that
doesn't necessarily mean it provides translation for the device we
care about. Replace iommu_present() with a more appropriate check.
On Qualcomm platforms the IOMMU can be specified either for the MDP/DPU
device or for its parent MDSS device depending on the actual platform.
Check both of them, since that is how both DPU and MDP5 drivers work.

From testing on sc7180-trogdor devices, reading the GMU registers
needs the GMU clocks to be enabled. Those clocks get turned on in
a6xx_gmu_resume(). Confusingly enough, that function is called as a
result of the runtime_pm of the GPU "struct device", not the GMU
"struct device". Unfortunately the current a6xx_gpu_busy() grabs a
reference to the GMU's "struct device".
The fact that we were grabbing the wrong reference was easily seen to
cause crashes that happen if we change the GPU's pm_runtime usage to
not use autosuspend. It's also believed to cause some long tail GPU
crashes even with autosuspend.
We could look at changing it so that we do pm_runtime_get_if_in_use()
on the GPU's "struct device", but then we run into a different
problem. pm_runtime_get_if_in_use() will return 0 for the GPU's
"struct device" the whole time when we're in the "autosuspend
delay". That is, when we drop the last reference to the GPU but we're
waiting a period before actually suspending then we'll think the GPU
is off. One reason that's bad is that if the GPU didn't actually turn
off then the cycle counter doesn't lose state and that throws off all
of our calculations.
Let's change the code to keep track of the suspend state of
devfreq. msm_devfreq_suspend() is always called before we actually
suspend the GPU and msm_devfreq_resume() after we resume it. This
means we can use the suspended state to know if we're powered or not.
NOTE: one might wonder when exactly our status function is called when
devfreq is supposed to be disabled. The stack crawl I captured was:
msm_devfreq_get_dev_status
devfreq_simple_ondemand_func
devfreq_update_target
qos_notifier_call
qos_max_notifier_call
blocking_notifier_call_chain
pm_qos_update_target
