Currently checkpatch is enforcing an 80 character column
limit. This should not be applied for patches modifying
checkpatch.

Add CLK_* macros used in MSM clock drivers to the list of exceptions
for the "Macros with complex values should be enclosed in parenthesis"
test.
Also, allow spaces following open branckets for macros where the
macro is the first token on the line, the space preceds a decimal
number, and the line ends with ")," or ")". Such arrangements can
be useful for aligning numerical columns of tables when the rows
are described by macros.

Currently when UAPI headers for a staging driver are kept under the
drivers/staging directory, `make headers_install' installs them to
<install_prefix>/drivers instead of the usual <install_prefix>/usr. This
is a non-standard and unexpected location. Fix this by doing the
necessary string substitutions so that the UAPI headers for staging
drivers end up in <install_prefix>/usr/include/linux/staging.

in the header file. Move the header to uapi to make
it accesible to user space.
Fix checkpatch errors to replace deprecated functions
and hardcoded error return values.

The eMMC 4.5 spec for RPMB accesses is not very clear on whether
user parition accesses can be allowed in the middle of RPMB accesses.
Due to this ambiguity, it turns out this is implementation defined
and certain cards support it while others do not.
In order to allow this feature to function across a wide variety of
cards, this patch takes the pessimistic approach and ensures that any
RPMB access is completed before user partition can be accessed.

perf trace user provides a debugfs node to which a marker string
can be written by userspace. This will create an ftrace and perf
entry containing the current value of L1 and L2 enabled
performance counters and the marker string. This allows usermode
programs to write snapshot entries at specific places in their
code, then see the difference in performance counter values
between those locations.

Due to the mismatch between counter values saved across CPU hotplug

Provide a mechanism to track which msm perf patches
are present in a kernel. Some kernel branches do not
include all patches which causes problems trying
to debug perf issues. This framework provides a way
to keep track of which patches have been included
in a build.

Preserves the bitfields of PMCR(AArch32)/PMCR_EL0(AArch64)
during PMU reset. Reset routine should write a 1 to PMCR.C and PMCR.P
fields only to reset the counters. Other fields should not be changed
as they could be set before PMU initialization and their value must
be preserved even after reset.

Simultaneous buffer maps with read and write permissions are
possible due to the asynchronous nature of MDSS driver.
Client stages the same buffer on MDP & ROTATOR. It calls the map
API for both at the same time. Due to concurrency, the source buffer
is mapped by MDP before and is ref-counted. ROTATOR API called later never
updates the permission which is required for dst buffer.
This leads to permission fault. Requesting the map with DMA_BIDIRECTIONAL
flag to fix the issue.

Display Steam Compression (DSC) use-cases requires parameter calculations
that affect MDP and DSI separately. Current implementation is not modular
and calculates all the parameters in one big subroutine. Due to this, an
issue has occurred where parameters that affect DSI relies on picture
width where as DSI parameters should be calculated only based on
uncompressed width to a particular DSI controller.
Also current MDP driver tries to service DSC setup for all different
topologies in a single subroutine and has become very error prone.
Modularize MDP DSC setup so that it is easy to maintain and also add
support for partial update for 4K DSC split-panel.

MDSS software should trigger frame timeout when command mode
interface recovery is in progress. After this new place for
event, there is a small window where wait4pingpong and recovery
path both can trigger this event. Use atomic_add_unless api
instead of read and dec so that it would add protection and
avoids timeline update multiple times for same frame update.

During kernel boot up, the splash memory is unmapped and released
at the beginning of first display commit during overlay start. By this
time, MDP will not start fetching the new buffers that are queued as part
of first commit. This can cause IOMMU page faults on the splash memory
since the buffer is unmapped but IOMMU is attached as part of overlay
kickoff. Hence, perform splash cleanup after waiting for a vsync
during kickoff cycle.
