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.

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.

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

The programming of the DSI Phy timing registers are dependent on
link frequency. In the current implementation, these values are
pre-computed statically based on the link rate required for a particular
panel. This approach does not scale very well, especially for use cases
when dynamically changing the refresh rate or resolution for a panel.
To address this, add support to dynamically compute the value for dsi
phy timing registers based on a particular link rate.
