When entering ERROR_RECOVERY, the forced disconnect should
be processed first by queuing the work function to handle it
in the usual way. The required minimum delay should then be
done after this, before restoring the port to dual-role, and
thereby re-establishing the source/sink connection.

queue_delayed_work(), which is based on jiffies, is not
appropriate for accurate timing, such as timeouts needing
resolution on the order of milliseconds. Instead introduce
an hrtimer which upon timeout will call regular queue_work().
Redefine timeout values based on the PD spec minimum amounts
as these are generally the minimum time the policy engine
needs to wait before peforming the next action.
msleep() is also jiffies-based, so replace with usleep_range()
for the same reason. Further, PE_SRC_TRANSITION_SUPPLY can
simply be inlined as part of the PE_SRC_NEGOTIATE_CAPABILITY state
using an in-place sleep.

The QPNP PD PHY supports BIST modes as required by the USB PD
specification. Specifically for BMC signaling, upon reception
of BIST requests to enter Carrier Mode 2 or Test Data Mode,
place the PHY in the appropriate test mode when receiving
these messages in the RX handler.
While at it, remove the unnecessary kmalloc in the RX handler
as the temporary 32-byte buffer can be placed on the stack.

Add explicit write memory barrier before turning off QMP PHY clock to
make sure previous POWER DOWN operation (in disconnect case) or
putting PHY into autonomous mode (in suspend case) is completed.
Similar way add write memory barrier after performing POWER UP
operation (in connect case) or disabling PHY autonomous mode (in
resume case).

Both flags must be set to reallow CPRh hardware closed-loop

In some cases the userspace can do a back to back write() followed by
close(). In such cases the tty framework does account for this by asking
the driver the status of the tx buffer and if not empty wait for a timeout
computed as a function of the current port baud rate.
However in some cases, this timeout doesn't seem sufficient, so when
checking the state of the tx buffer insert an extra delay if not empty
before returning to the framework. This will do a double wait at driver
and at framework, but this shouldn't adversely affect timing of usecases
and the flip side of having a pending byte in the tx buffer can result
in the peer hardware being left in a bad state.

In a case where gate work is called as part of cancel work
from ungate path the clk state would be marked as REQ_CLKS_ON.
There is no point gating the clocks and then end up turning
them ON immediately in ungate work, save time by skipping the
gate work and change the clk state to CLKS_ON as they are not
turned off yet.
