Add cpu cache nodes to represent the cache hierarchy and
to specify the dump size of each cache.
While at it also add the cache dump nodes which will enable
reserving the memory for cache dumps.

Currently we are using the argument passed to
the function to fill the array values as is
without checking for the sanity. This commit
will add a sanity check on function argument
to avoid array index out of bound access.

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.

For sysfs calls which generate deferred work, prevent

Forward thread acquired v4l2_ctrl->handler->lock in
v4l2_s_ctrl() and waiting for response from response thread.
Response thread was blocked on core->lock which was acquired
by second forward thread. The second forward thread acquired
core->lock and called v4l2_g_ctrl() in msm_comm_get_mbs_per_sec()
where it was blocked on same v4l2_ctrl->handler->lock and hence
response thread was not unblocked. Resolve the deadlock issue
by avoiding v4l2_g_ctrl() call in msm_comm_get_mbs_per_sec().

Some UFS devices violate T-HIBERN8_ENTER_TX time when moving Device
TX (Host RX) lane-1 from SLEEP to HIBERN8 at the end of burst.
M-PHY specification defines max value of 1000 ns for
T-HIBERN8_ENTER_TX but these devices drive DIF-N for 3432 ns. This can
cause the broken link situation after link starup.
This change fixes above issue by increasing host PHY's RX_MIN_HIBERN8_TIME
to 8us (we are giving some additional margin though device needs 3.432us).
