Add tracepoints for the mem-buf driver to collect a sequence of
events, as well as state to ascertain how much progress the
allocation process makes.

When releasing memory, notify the owner of the memory that it
can be reclaimed only if the recipient VM has successfully
released the memory. There is also no reason to continue
to hold onto the mem-buf descriptor memory if a failure
occurs when relinquishing the memory, so free those structures
as well, independent of the result of the relinquish operation.
While we're here, touch up some of the error logging in the
error paths as well.

The state of memory--with respect to access control--is unknown
when a hyp_assign() call fails because the underlying SCM call
fails. In these cases, it is not safe to access the memory, so
we should not free it back to the system.

The allocation code hot-adds the memory from another VM through
the memory hotplug code to create the S1 CPU MMU mappings. The memory
hotplug code can only add memory at a subsection granule, meaning
that all memory requests must be subsection size aligned. Thus,
enforce all allocation requests to be subsection size aligned.

EUD HUB functionality is relevant into USB device mode only. Hence when
using USB host mode, continue performing reset and initialization
functionality with HSPHY even though EUD is enable. If EUD is enable
while starting host mode, re-enable EUD whie exiting host mode.

Currently usb speed override functionality doesn't work as expected
when usb role switch based notification is used. Hence move usb speed
override functionality out side edev check within dwc3_resume_work()
API. Also update maximum_speed as max hw supported speed out side
edev check.

cpu_isolated_mask can only be used when SCHED_WALT is enabled. The
addition of the cpu_isolated_mask causes ABI to break. Thus, compile
references to cpu_isolated_mask only when SCHED_WALT is enabled.

The FORCE_MEM_CORE_ON bits default to 0 and this is fine for most use
cases. However, USB needs FORCE_MEM_CORE_ON=1 to properly retain its
memories when USB APM switches from CX to MX. This can't just be a
one-time setting since the FORCE_MEM_CORE_ON bits need to be set/cleared
upon USB cable connect/disconnect for power optimization. Add fake
clocks to allow the USB client to control them.

FM app is using the VIDIOC DQBUF ioctl to read the
event from rtc6226 driver. VIDIOC DQBUF ioctl needs
the v4l2buf type as V4L2_BUF_TYPE_PRIVATE and it
is Deprecated and not recommend to use in latest
kernel version.Also upstream kernel code doesn't
have the VIDIOC DQBUF as a valid ioctl.
Implement file read functionality to read the events
from rtc6226 driver.

AMOLED ECM (Embedded Current Measurement) is a method to measure OLED
display power consumption with a time granularity in sub-frame or

longer period.
