The bus->clk_stop_timeout member is only initialized to a non-zero value
during the codec driver probe. This can lead to corner cases where this
value remains pegged at zero when the bus suspends, which results in an
endless loop in sdw_bus_wait_for_clk_prep_deprep().
Corner cases include configurations with no codecs described in the
firmware, or delays in probing codec drivers.
Initializing the default timeout to the smallest non-zero value avoid this
problem and allows for the existing logic to be preserved: the
bus->clk_stop_timeout is set as the maximum required by all codecs
connected on the bus.

Only exit sdw_handle_slave_status() right after calling
sdw_program_device_num() if it actually programmed an ID into at
least one device.
sdw_handle_slave_status() should protect itself against phantom
device #0 ATTACHED indications. In that case there is no actual
device still on #0. The early exit relies on there being a status
change to ATTACHED on the reprogrammed device to trigger another
call to sdw_handle_slave_status() which will then handle the status
of all peripherals. If no device was actually programmed with an
ID there won't be a new ATTACHED indication. This can lead to the
status of other peripherals not being handled.
The status passed to sdw_handle_slave_status() is obviously always
from a point of time in the past, and may indicate accumulated
unhandled events (depending how the bus manager operates). It's
possible that a device ID is reprogrammed but the last PING status
captured state just before that, when it was still reporting on
ID #0. Then sdw_handle_slave_status() is called with this PING info,
just before a new PING status is available showing it now on its new
ID. So sdw_handle_slave_status() will receive a phantom report of a
device on #0, but it will not find one.

The correct way to handle interrupts is to clear the bits we
are about to handle _before_ handling them. Thus if the condition
then re-asserts during the handling we won't lose it.
This patch changes cdns_update_slave_status_work() to do this.
The previous code cleared the interrupts after handling them.
The problem with this is that when handling enumeration of devices
the ATTACH statuses can be accidentally cleared and so some or all
of the devices never complete their enumeration.
Thus we can have a situation like this:
- one or more devices are reverting to ID #0
- accumulated status bits indicate some devices attached and some
on ID #0. (Remember: status bits are sticky until they are handled)
- Because of device on #0 sdw_handle_slave_status() programs the
device ID and exits without handling the other status, expecting
to get an ATTACHED from this reprogrammed device.
- The device immediately starts reporting ATTACHED in PINGs, which
will assert its CDNS_MCP_SLAVE_INTSTAT_ATTACHED bit.
- cdns_update_slave_status_work() clears INTSTAT0/1. If the initial
status had CDNS_MCP_SLAVE_INTSTAT_ATTACHED bit set it will be
cleared.
- The ATTACHED change for the device has now been lost.
- cdns_update_slave_status_work() clears CDNS_MCP_INT_SLAVE_MASK so
if the new ATTACHED state had set it, it will be cleared without
ever having been handled.
Unless there is some other state change from another device to cause
a new interrupt, the ATTACHED state of the reprogrammed device will
never cause an interrupt so its enumeration will not be completed.

Don't re-enumerate a peripheral on #0 until we have seen and
handled an UNATTACHED notification for that peripheral.
Without this, it is possible for the UNATTACHED status to be missed
and so the slave->status remains at ATTACHED. If slave->status never
changes to UNATTACHED the child driver will never be notified of the
UNATTACH, and the code in sdw_handle_slave_status() will skip the
second part of enumeration because the slave->status has not changed.
This scenario can happen because PINGs are handled in a workqueue
function which is working from a snapshot of an old PING, and there
is no guarantee when this function will run.
A peripheral could report attached in the PING being handled by
sdw_handle_slave_status(), but has since reverted to device #0 and is
then found in the loop in sdw_program_device_num(). Previously the
code would not have updated slave->status to UNATTACHED because it had
not yet handled a PING where that peripheral had UNATTACHED.
This situation happens fairly frequently with multiple peripherals on
a bus that are intentionally reset (for example after downloading
firmware).

Ensure that if sdw_handle_slave_status() sees a peripheral
has dropped off the bus it reports it to the client driver.
If there are any devices reporting on address 0 it bails out
after programming the device IDs. So it never reaches the second
loop that calls sdw_update_slave_status().
If the missing device is one that is now showing as unenumerated
it has been given a device ID so will report as attached next
time sdw_handle_slave_status() runs.
With the previous code the client driver would only see another
ATTACHED notification because the UNATTACHED state was lost when
sdw_handle_slave_status() bailed out after programming the
device ID.
This shows up most when the peripheral has to be reset after
downloading updated firmware and there are multiple of these
peripherals on the bus. They will all return to unenumerated state
after the reset, and then there is a mix of unattached, attached
and unenumerated PING states from the peripherals, as each is reset
and they reboot.

The cadence IP explicitly reports slave status changes with bits for
each possible change. The function cdns_update_slave_status() attempts
to translate this into the current status of each of the slaves.
However when there are multiple peripherals on a bus any slave that did
not have a status change when the work function ran would not have it's
status updated - the array is initialised to a value that equates to
UNATTACHED and this can cause spurious reports that slaves had dropped
off the bus.
In the case where a slave has no status change or has multiple status
changes the value from the last PING command is used.

The SoundWire specification allows the device number to be allocated
at will. When a system includes multiple SoundWire links, the device
number scope is limited to the link to which the device is attached.
However, for integration/debug it can be convenient to have a unique
device number across the system. This patch adds a 'dev_num_ida_min'
field at the bus level, which when set will be used to allocate an
IDA.
The allocation happens when a hardware device reports as ATTACHED. If
any error happens during the enumeration, the allocated IDA is not
freed - the device number will be reused if/when the device re-joins
the bus. The IDA is only freed when the Linux device is unregistered.

The DSDT for this device has a number of problems:
a) it lists rt711 on link0 and link1, but link1 is disabled
b) the rt711 entry on link0 uses the wrong v2 instead of v3 (SDCA)
c) the rt1316 amplifier on link3 is not listed.
Add a remapping table to work-around these BIOS shenanigans.

The capabilities enabled for multi-link are required as part of the
programming sequences, even when a stream uses a single link we still
use the syncArm/syncGo sequences. Therefore the TODO is no longer
necessary.

As diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a
bunch of new drivers (as usual), while there have been some
significant (but almost invisible) improvements in ALSA core
side, too. Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user
won't notice, but on the devices with tons of control elements,
it can be visibly faster
- Support for input validation for controls; this will harden
for badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer
in situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some
board integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
WAS883x, and Texas Instruments TAS2780
HD- and USB-audio:
- Continued improvement for CS35L41 (sub)codec support
- More quirks for various devices (HP, Lenovo, Dell, Clevo)

When a pipeline is split into FE and BE parts, the BE pipeline may need to
be triggered separately in the BE trigger op. So add the trigger callback
in the link_res ops that will be invoked during BE DAI trigger.
