Some Windows hosts are not dropping DTR during suspend, but are
setting DTR as part of resume. Hence, send DTR set to zero to
the Modem when the rmnet interface is suspended.

Upper layers are not acquiring the locks properly, hence wakelock release
timeout is increased to 500 ms. This logic and value is derived from

kmalloc allocates physically contiguous memory and
may fail for larger allocations due to fragmentation.
The large allocations are caused by the fact that the
scatterlist structure is 24 bytes and the array size
is proportional to the number of pages being mapped.

Add a thermal driver to poll and detect any thermal condition at boot
and limit max cpu frequency on a thermal condition. This driver is
intended to limit cpu thermal output until the userspace thermald
kicks in. The thermald will disable this driver and take over the
cpu thermal sensing and mitigation.

Add kernel API to read TSENS temperature for clients
in the kernel space. Currently the TSENS driver only
supports reading the TSENS temperature from the
thermal sys.
Split the TSENS initialization into two parts.
First is to perform the initial calibration that is
used to convert the raw ADC code to Degrees Celcius
and initialize the TSENS HW. Second is to register the
TSENS driver to the linux thermal framework and create
the temperature zones that will be accessed by the
Thermal daemon to set thresholds, read the temperature
and receive notifications.

When a write callback returns -EPROTO, treat it as if the device is
disconnected and disallow further calls to write. This will allow the
caller to gracefully handle the error until a disconnect event finally
comes and is able to notify the caller via a platform_device removal.

Rmnet gadget driver sets IOC bit for every request having IP packet
data in TX direction. This causes the driver to spend more time in
servicing interrupts which degrades the overall performance of the
driver. Hence reduce the number of interrupts by setting IOC bit for
certain number of requests being queued.

Add a new API, pm8xxx_preload_dVdd, which will preload the dVdd
regulator on PMIC PM8901 chips during off state. This can help
to reduce fluctuations in the dVdd voltage during startup at the
cost of additional off state current draw.
This API should only be called if dVdd startup issues are
suspected.

When the usb_compostite_probe function fails, the USB enumeration fails.
Hence accessing the USB related sysfs entries results in null pointer
dereference crash.
This change fixes it by handling all possible error conditions and
destroy the sysfs entries in the init() function.

When an input event and CPU1 hotplug occurs at the same
time, a race condition can happen between cpufreq and
cpu hotplug resulting in a kernel panic.
When a hotplug operation is underway on CPU1,
__cpufreq_remove_dev is called. __cpufreq_remove_dev gets
the lock, proceeds to free the policy info of the current
governor and calls the ondemand governor with a STOP event.
If an input event occurs around the same time, it waits
for __cpufreq_remove_dev to release the lock. Meanwhile,
the ondemand governor clears some of its settings, but
fails to clear its local current policy. As soon as the
input event handler acquires the lock, it now uses the
invalid ondemand current policy handle to make frequency
changes. This results in a kernel panic.
Skip making frequency changes if this condition happens.
