Pull char / misc driver updates from Greg KH:
"Here is the big set of char/misc driver changes for 5.15-rc1.

Lots of different driver subsystems are being updated in here,
notably:

- mhi subsystem update

- fpga subsystem update

- coresight/hwtracing subsystem update

- interconnect subsystem update

- nvmem subsystem update

- parport drivers update

- phy subsystem update

- soundwire subsystem update

and there are some other char/misc drivers being updated as well:

- binder driver additions

- new misc drivers

- lkdtm driver updates

- mei driver updates

- sram driver updates

- other minor driver updates.

Note, there are no habanalabs driver updates in this pull request,
that will probably come later before -rc1 is out in a different
request.

All of these have been in linux-next for a while with no reported
problems"

soundwire: cadence: override PDI configurations to create loopback

When we set a source PDI, the target PDI parameters will be overridden
by the source register values. The loopback streams can be
independently enabled on each link.

While the loopback source and target can be configured before any
stream is active on each link, the loopback stream should only be
prepared/triggered when the playback stream is prepared. Otherwise all
registers might be programmed to their reset values and the loopback
will not succeed. The SoundWire bus driver currently does not allow
two streams to be triggered at the same time, so the playback will
have to be started first, and later the loopback.

soundwire: cadence: add debugfs interface for PDI loopbacks

For debug, it's interesting to create a loopback stream for each link
and use debugfs to set a source and target PDI. The target PDI would
need to be an RX port and use the same register configurations as the
source PDI. This capability allows e.g. for the headphone playback
stream to be snooped on the headset capture stream, or alternatively
for the addition of a dedicated loopback stream, in addition of
regular capture for that link.

This patch only adds the debugfs part, the port/PDI handling will be
handled in the next patches.

soundwire: cadence: add paranoid check on self-clearing bits

The Cadence IP exposes a small number of self-clearing bits in
the MCP_CONTROL and MCP_CONFIG_UPDATE registers.

We currently do not check that those bits are indeed cleared,
e.g. during resume operations. That could lead to resuming peripheral
devices too early.

In addition, if we happen to read these registers, update one of the
fields and write the register back, we may be writing stale data that
might have been cleared in hardware. These sort of race conditions
could lead to e.g. doing a hw_reset twice or stopping a clock that
just restarted. There is no clear way of avoiding these potential race
conditions other than making sure that these registers fields are
cleared before any read-modify-write sequence. If we detect this sort
of errors, we only log them since there is no clear recovery
possible. The only way out is likely to restart the IP with a
suspend/resume cycle.

Note that the checks are performed before updating the registers, as
well as after the Intel 'sync go' sequence in multi-link mode. That
should cover both the start and end of suspend/resume hardware
configurations. The Multi-Master mode gates the configuration updates
until the 'sync go' signal is asserted, so we only check on init and
after the end of the 'sync go' sequence.

The duration of the usleep_range() was defined by the GSYNC frequency
used in multi-master mode. With a 4kHz frequency, any configuration
change might be deferred by up to 250us. Extending the range to
1000-1500us should guarantee that the configuration change is
completed without any significant impact on the overall resume
time.

soundwire: cadence_master: always set CMD_ACCEPT

The Cadence IP can be configured in two different ways to deal with
CMD_IGNORED replies to broadcast commands. The CMD_ACCEPT bitfield
controls whether the command is discarded or if the IP proceeds with
the change (typically a bank switch or clock stop command).

The existing code seems to be inconsistent:
a) For some historical reason, we set this CMD_ACCEPT bitfield during
the initialization, but we don't during a resume from a clock-stoppped
state.
b) In addition, the loop used in the clock-stop sequence is quite
racy, it's possible that a device has lost sync but it's still tagged
as ATTACHED.
c) If somehow a Device loses sync and is unable to ack a broadcast
command, we do not have an error handling mechanism anyways. The IP
should go ahead and let the Device regain sync at a later time.

Make sure the CMD_ACCEPT bit is always set.
