HACK: drm/msm/adv7511: Don't rely on interrupts for EDID parsing

BugLink: http://bugs.launchpad.net/bugs/1763040
The adv7511 driver is currently woken up on successful EDID read
after a EDID_READY interrupt is triggered by the chip. If the driver
doesn't get the interrupt within 200 ms, its concluded that we failed
to read EDID from the monitor.

This interrupt doesn't seem to occur consistently in certain use cases
(for example, if we execute power-on -> get_modes -> power-off
repeatedly, this can be done by calling xrandr successively really
fast).

For now, execute the lesser preferred POLL path where the driver
manually checks on the interrupt status register after every 25ms.

We should ideally rootcause why we don't get EDID_READY interrupts
consistently instead of relying on the above approach.

drm/bridge/adv7511: Delay clearing of HPD interrupt status

BugLink: http://bugs.launchpad.net/bugs/1763040
When a hotplug event occurs, the adv7511 interrupt handler schedules
an hpd work after clearing the interrupt status registers
(ADV7511_REG_INT(x). The hpd work calls a drm helper that sends a
uevent to notify the userspace about the hotplug event.

On a hotplug connect, the userspace generally acts upon this uevent by
calling an ioctl (DRM_IOCTL_MODE_GETCONNECTOR) that probes on the
connector.This results in the connector's detect() drm_connector_func
being called. In the ADV7511 driver, this is a wrapper around the
adv7511_detect() call.

adv7511_detect() checks on the same interrupt ADV7511_REG_INT(0)
register which was previously cleared by the interrupt handler,
resulting in the func not realizing that a hotplug connect event
took place. ADV7511 loses its state when a disconnect happens, and
the driver needs to do a power-on to re-enable the hardware. This
fails to happen since calls to adv7511_detect() can fail to identify
that a hotplug connect took place.

Fix this by delaying the clearing of the ADV7511_INT0_HPD status flag.
Let the call to adv7511_hpd() be the only one responsible for clearing
this bitfield.

Note: Not sure if this is the best approach. Clearing a status flag
outside of the interrupt handler is generally looked down upon.

PM / OPP: Support adjusting OPP voltages at runtime

BugLink: http://bugs.launchpad.net/bugs/1763040
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage
without software intervention. Add an API to the OPP library for
the former case, so that AVS type devices can update the voltages
for an OPP when the hardware determines the voltage should
change. The assumption is that drivers like CPUfreq or devfreq
will register for the OPP notifiers and adjust the voltage
according to suggestions that AVS makes.

power: avs: Add support for CPR (Core Power Reduction)

BugLink: http://bugs.launchpad.net/bugs/1763040
CPR (Core Power Reduction) is a technology that reduces core
power on a CPU or other device. It reads voltage settings in
efuse from product test process as initial settings and populates
OPPs for the device being "monitored". Each OPP corresponds to a
"corner" that has a range of valid voltages for a particular
frequency. While the device is running at a particular frequency,
CPR monitors dynamic factors such as temperature, etc. and
adjusts the voltage for that frequency accordingly to save power
and meet silicon characteristic requirements.

This driver is based on work by others on codeaurora.org[1].

wcn36xx: fix incorrect assignment to msg_body.min_ch_time

BugLink: http://bugs.launchpad.net/bugs/1763040
The second assignment to msg_body.min_ch_time is incorrect, it
should actually be to msg_body.max_ch_time.

Thanks to Bjorn Andersson for identifying the correct way to fix
this as my original fix was incorrect.

wcn36xx: Reduce spinlock in indication handler

BugLink: http://bugs.launchpad.net/bugs/1763040
The purpose of pushing indication on a list and handle these in a
separate worker is to allow the handlers to sleep. It does therefor not
make much sense to hold the queue spinlock through the entire indication
worker function.

By removing items from the queue early we don't need to hold the lock
throughout the indication worker, allowing the individual handlers to
sleep.

wcn36xx: Add hardware scan offload support

BugLink: http://bugs.launchpad.net/bugs/1763040
Current hw_scan implementation does not trigger offloaded
hardware scan and seems to only put the device in a kind of
listening mode (beacon/probe-response) for software scan.
Since no probe request are generated by the software, current
scanning method is similar to a passive scan.

This patch introduces support for 'true' hardware offloaded scan.
Hardware scan is configured and started via the start-scan-offload
firmware message. Once scan has been completed a scan indicator
message is received from firmware.

Moreover, this patch includes support for directed probe-request,
allowing connection with hidden APs. It also fixes scan issues with
band-steering AP which are not 'visible' with passive scan (due to
hidden ssid in beacons).

Let's keep the 'legacy' scanning method in case scan-offload is not
supported.

wcn36xx: set default BTLE coexistence config

BugLink: http://bugs.launchpad.net/bugs/1763040
If the value for the firmware configuration parameters
BTC_STATIC_LEN_LE_BT and BTC_STATIC_LEN_LE_WLAN are not set the duty
cycle between BT and WLAN is such that if BT (including BLE) is active
WLAN gets 0 bandwidth. When tuning these parameters having a too high
value for WLAN means that BLE performance degrades.
The "sweet" point of roughly half of the maximal values was empirically
found to achieve a balance between BLE and Wi-Fi coexistence
performance.

drm/msm: gpu: Only sync fences on rings that exist

drm/msm: fix msm_rd_dump_submit prototype

BugLink: http://bugs.launchpad.net/bugs/1763040
The prototype of msm_rd_dump_submit() has recently changed. However,
we have two declarations of this functions, and the other one
remains the old version, leading to this:

drivers/gpu/drm/msm/msm_gpu.c: In function 'recover_worker':
drivers/gpu/drm/msm/msm_gpu.c:295:23: error: passing argument 1 of 'msm_rd_dump_submit' from incompatible pointer type [-Werror=incompatible-pointer-types]

This changes the second one to match the first again.
