For some platforms due to HW limitation timing db property
can not be a shared property, so making this property as interface
specific for MDSS, instead of shared.

If timing db(Double Buffered) property is enabled, then MDP FLUSH
bit needs to be set in order to push the data to video interface.
Currently this property is used as a shared property for both DSI
interfaces. But in case of chipsets where there is no FLUSH bit
defined for the secondary DSI interface, this will cause issue.
So moving the property to each controller specific instead of shared.

qseecom_send_modfd_cmd_64 converts non-contiguous ION memory fd to
scatter-gather physical address list, and supports up to 512 SG list
entries. Now, 512 is not enough if client wants to send large data
in a fragmented system. In this change, if SG list entry number is
larger than 512, we will allocate a new contiguous kernel buffer,
then save all SG entries into this new buffer.

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.
