Upon any CQ error, the driver tries to halt the CQE first and
if it fails to halt, then CQE is disabled. The error handling
work function mmc_blk_cmdq_err() also tries to HALT the CQE
at couple of places and takes some action based on the HALT
success/error status. But since CQE is disabled, we should not
treat any errors of CQE halt/unhalt as critical and in fact,
we should not even attempt to halt/unhalt.

The legacy interrupts are enabled as part of CQE halt. But there could
be few cases, where halt fails. In those cases, CQE is disabled without
enabling legacy interrupts. Without this we cannot send any commands
like status CMD13 in legacy mode as part of error handling work.

There could be cases where CQE halt might fail and in which
case, CQE gets disabled as part of error handling.
In this case, !mmc_host_halt() will be true and the commands
sent in legacy mode are getting software request timeout errors
as they are getting handled as cmdq irq.
Hence, add !mmc_host_cq_disable() check as well in addition to
!mmc_host_halt() in sdhci_irq() before considering it as a
cmdq irq.

As per hdcp 2.2 specifications, send the stream type message
to sink at a specified address in case sink is a receiver.
Update the messages to be sent to sink with the message received
from TZ and tear down the session in case it time's out.
Also, enable encryption after stream management message
exchange for hdcp repeaters to avoid unnecessary link failures.

concurrent sysfs calls on the fw updater can cause
ugly race conditions. Return EBUSY on concurrent sysfs calls.
For sysfs calls which generate deferred work, prevent
the deferred work from running concurrently with other
sysfs calls.
Also check that ext_data_source is appropriately sized
and allocated, based on a patch by
Gengjia Chen (chengjia4574@gmail.com).

This change prevents blocking IOCTLs with wrong command
number or wrong magic Number. IOCTL handler should first
check that the command is valid and only then wait for
IPA driver initializations to finish.

Some targets doesn't seem to have vbif_nrt_phys in dtsi
file but we still register the debug node for vbif_nrt_reg
and off without checking whether it exists or not. Ensure
this is checked to avoid null pointer reference.

Add support to switch non-standard framerate.To achieve this,
first map the fps to standard fps and then tune pixel clock
based non-standard framerate. Panel porches might need update
before pixel clock tuning based on standard framerate mapping.

BTA complete interrupt comes and turns off the clocks. In another
thread we read the panel status and DSI ack returns error. In the
error condition we are trying to read some DSI registers even
when the clocks are turned off.

Changing the error return value for lineptr sysfs entries, when
the sysfs operation is not allowed. Returning EAGAIN might make
the verification tests to continuously query the sysfs nodes, or
block it. Returning EPERM will fail the query, which is expected.

Ringbuffer timer should always be reset whenever we finish
preempting to that ringbuffer. Currently, there is a case where
wptr in the hardware and the kgsl are identical and thus
the timer isn't reset. Reset the timer regardless if they are
identical or not.
There is one special case when we shouldn't reset the timer.
This happens when we try to figure out next ringbuffer to preempt
but the next ringbuffer is the same one as current. In that case,
if nothing new got submitted to this ringbuffer, then don't reset
the timer.
