MDSS client may want to reuse the pipe during
boot up which are currently in use. The pipe
allocation fails when these pipes are in handoff
state and atomic API tries to reallocate them.
Moving them to used list allows client to reuse
them at early stage without waiting for first valid
kickoff.

Add sysfs node to trigger cable disconnect/connect hot plug
interrupts. Power off 5v regulator which provides 5v to sink
which in turn pulls hpd line low resulting in disconnect hot

SCM (Secure Channel Manager) driver is used to communicate
with the secure world entities like trustzone and hypervisor.
As a part of the communication we expect to give certain
input, output operands and the caller of the scm_callX
API would expect that output values or return values
of the scm_callX should not get corrupted (if they depend on it).
Due to Kasan instrumentation of the SCM driver following
code is getting instrumented with Kasan __asan_store8_noabort
APIs which would internally check if the memory access is allowed
and it is the functionality of the Kasan to check/instrument
the load and stores.
if (ret1)
*ret1 = r1;
if (ret2)
*ret2 = r2;
if (ret3)
*ret3 = r2;
All will be fine for the first *ret1 = r1; execution since
GCC has generated the code which saves the x1 value (r1)
into the another register but the execution of the
__asan_store8_noabort API after the saving of the register
corrupts the x2 and x3 when it returns. GCC has no knowledge
at this point to save the x2 and x3.
Due to this x2 and x3 is loaded with the Kasan shadow
offset value and Kasan shifted (>> 3) address.
Since x2 and x3 (r2 and r3 in the code above) would be used
as the ret2 and ret3 for the caller of the scm_callX API
the caller would get the wrong return values (if it needs them).
QSEECOM is one such driver which uses these ret2 and ret3 values
and due to this corruption QSEECOM driver was treating it as
SCM call failure, though the bug described above due to Kasan
instrumentation would be applicable to any caller needing
the right values of the ret2 and ret3.
SCM driver is very small and simple and we would not expect
the Out of bound or use-after-free errors for it, so it would
be fine to skip it from the Kasan instrumentation.

The G-Link SSR driver currently does not specify a timeout for
requesting RX intents. If the remote processor is not responding, the
glink_tx() call for sending the SSR notification could wait forever for
an RX intent and block SSR processing for the entire system.
Introduce a 500ms timeout, and restart the remote processor in question
if an intent is not queued within that time. This unblocks SSR
processing in addition to resetting the remote processor.

During glink_tx(), G-Link can wait for an unlimited amount of time for
the remote side to queue an RX intent. In some cases, e.g. SSR, the wait
must be restricted to a short time, but in the current implementation,
glink_tx() can continue to block indefinitely.
Add a configurable timeout value to the G-Link channel context, which is
set in the channel open configuration. If the value is set to 0, treat
it as an infinite timeout. This allows a timeout to be put in place by
the client for sensitive cases such as SSR where a very limited amount of
time can be spent waiting for an intent.

Threshold list will be read in interrupt context. Using
a lock in the interrupt context is not acceptable, but the
list traversal needs to be protected. Because the threshold
list can be updated with a new threshold or an existing
threshold can be removed. Doing a list traversal during the
list mutation may result in unassigned memory access
violation. Use of list_for_each_entry_safe() function for
traversing, won't help. Because this function can help
only if the traversal loop removes the current element, that
is pointed by this iteration.
Use rcu to ensure a safe list traversal without a lock.
Addition or deletion to the threshold list is an infrequent
operation when compared to the threshold list read, which
happens when temperature threshold trips. Using rcu ensures
that read operations are done faster without getting
blocked by a lock and the list write operations are done
in a list safe fashion. Replace the list_for_each_entry_safe()
function with rcu safe list traversal function
list_for_each_entry_rcu(), wherever it is applicable.
