Add the needed DP PLL specific files to support
display port interface on msm targets.
The DP driver calls the DP PLL driver registration.
The DP driver sets the link and pixel clock sources.

The Arm arch timer can be used to calculate timestamp, the basic idea is
the arch timer's counter value can be recorded in the hardware tracing
data, e.g. the arch timer's counter value can be used for Arm CoreSight
(not now but might be implemented later) and Arm SPE. So we need a way
to convert
Since the arch timer's counter is used for SPE tracing data, and now
it's ready to use arch timer for sample's timestamp in Perf tool, this
patch is to enable timestamp by convert the arch timer counter value to
the time.
After enabling timestamp for Arm SPE with this patch, we can see the
x86 arch has provides the testing for conversion between tsc and perf
time, this patch studies it and writes a similar testing for conversion
between arch timer's counter and sample's time.
The testing approach firstly creates three time points:
Time point 1: 1st process's sample with perf

The only-root-readable /sys/module/$module/sections/$section files
did not truncate their output to the available buffer size. While most
paths into the kernfs read handlers end up using PAGE_SIZE buffers,
it's possible to get there through other paths (e.g. splice, sendfile).

Resending the fixes by describing more about the issue
and correcting typo
In concurrency usecase and reboot scenario we are
observing race condition and seeing NULL pointer
dereference crash. In shutdown path and system
recovery path we are destroying the same mutex
hence seeing crash.
This case is handled by mutex protection and
cancel delayed work items in work
In concurrency usecase and reboot scenario we are trying
to map fw.iommu_domain which is already unmapped during
shutdown. This is causing NULL pointer dereference crash.
This case is handled by adding necessary checks.
Call trace:
__iommu_map+0x4c/0x348
iommu_map+0x5c/0x70
For core ops we are having only write protect but there
is no read protect, because of this in multthreading
and concurrency, one CPU core is reading without wait
which is causing the NULL pointer dereferece crash.
one such scenario is as show below, where in one
