This is quite a busy release for regmap with two substantial features
being added:
- Support for register maps Soundwire 1.2 multi-byte operations,
allowing atomic support for registers larger than a single byte.
- Support for relaxed I/O without barriers in MMIO regmaps, allowing
them to be used efficiently on systems where default MMIO operations
include barriers.
There was also an addition and revert of use of the new Soundwire
support for RT715 due to build issues with the driver built in, my tests
only covered building it as a module, the patch wasn't just dropped as
it had already been merged elsewhere.

Here is the big driver core updates for 5.11-rc1
This time there was a lot of different work happening here for some
reason:
- redo of the fwnode link logic, speeding it up greatly
- auxiliary bus added (this was a tag that will be pulled in
from other trees/maintainers this merge window as well, as
driver subsystems started to rely on it)
- platform driver core cleanups on the way to fixing some
long-time api updates in future releases
- minor fixes and tweaks.
All have been in linux-next with no (finally) reported issues. Testing
there did helped in shaking issues out a lot :)

On shutdown the driver core calls the bus' shutdown callback also for
unbound devices. A driver's shutdown callback however is only called for
devices bound to this driver. Commit 9c30921fe7 ("driver core:

callbacks to bus callbacks, so the shutdown function must be prepared to
be called without a driver. Add the corresponding check in the shutdown

for handling HW queue completion interrupts, so add support.
The function accepts an affinity descriptor pointer, which covers all IRQs
expected for the device.
The function is devm class as the only current in-tree user will also use
devm method for requesting the interrupts; as such, the function is made

We have two flavours of platform-MSI:
- MSIs generated by devices for themselves (the usual case)
- MSIs generated on behalf of other devices, as the generating
device is some form of bridge (either a wire-to-MSI bridge,
or even a non-transparent PCI bridge that repaints the PCI
requester ID).
In the latter case, the underlying interrupt architecture may need
to track this in order to keep the mapping alive even when no MSI
are currently being generated.
Add a set of flags to the generic msi_alloc_info_t structure, as
well as the MSI_ALLOC_FLAGS_PROXY_DEVICE flag that will get
advertized by the platform-MSI code when allocating an irqdomain
for a device.

Device drivers usually depend on the fact that the devices that they
control are suspended in the same order that they were probed in. In
most cases this is already guaranteed via deferred probe.
However, there's one case where this can still break: if a device is
instantiated before a dependency (for example if it appears before the
dependency in device tree) but gets probed only after the dependency is
probed. Instantiation order would cause the dependency to get probed
later, in which case probe of the original device would be deferred and
the suspend/resume queue would get reordered properly. However, if the
dependency is provided by a built-in driver and the device depending on
that driver is controlled by a loadable module, which may only get
loaded after the root filesystem has become available, we can be faced
with a situation where the probe order ends up being different from the
suspend/resume order.
One example where this happens is on Tegra186, where the ACONNECT is
listed very early in device tree (sorted by unit-address) and depends on
BPMP (listed very late because it has no unit-address) for power domains
and clocks/resets. If the ACONNECT driver is built-in, there is no
problem because it will be probed before BPMP, causing a probe deferral
and that in turn reorders the suspend/resume queue. However, if built as
a module, it will end up being probed after BPMP, and therefore not
result in a probe deferral, and therefore the suspend/resume queue will
stay in the instantiation order. This in turn causes problems because
ACONNECT will be resumed before BPMP, which will result in a hang
because the ACONNECT's power domain cannot be powered on as long as the
BPMP is still suspended.
Fix this by always reordering devices on successful probe. This ensures
that the suspend/resume queue is always in probe order and hence meets
the natural expectations of drivers vs. their dependencies.

The current implementation of fw_devlink is very inefficient because it
tries to get away without creating fwnode links in the name of saving
memory usage. Past attempts to optimize runtime at the cost of memory
usage were blocked with request for data showing that the optimization
made significant improvement for real world scenarios.
We have those scenarios now. There have been several reports of boot
time increase in the order of seconds in this thread [1]. Several OEMs
and SoC manufacturers have also privately reported significant
(350-400ms) increase in boot time due to all the parsing done by
fw_devlink.
So this patch uses all the setup done by the previous patches in this
series to refactor fw_devlink to be more efficient. Most of the code has
been moved out of firmware specific (DT mostly) code into driver core.
This brings the following benefits:
- Instead of parsing the device tree multiple times during bootup,
fw_devlink parses each fwnode node/property only once and creates
fwnode links. The rest of the fw_devlink code then just looks at these
fwnode links to do rest of the work.
- Makes it much easier to debug probe issue due to fw_devlink in the
future. fw_devlink=on blocks the probing of devices if they depend on
a device that hasn't been added yet. With this refactor, it'll be very
easy to tell what that device is because we now have a reference to
the fwnode of the device.
- Much easier to add fw_devlink support to ACPI and other firmware
types. A refactor to move the common bits from DT specific code to
driver core was in my TODO list as a prerequisite to adding ACPI
support to fw_devlink. This series gets that done.

To check if a device is still waiting for its supplier devices to be
added, we used to check if the devices is in a global
waiting_for_suppliers list. Since the global list will be deleted in
subsequent patches, this patch stops using this check.
Instead, this patch uses a more device specific check. It checks if the
device's fwnode has any fwnode links that haven't been converted to
device links yet.

SYNC_STATE_ONLY device links only affect the behavior of sync_state()
callbacks. Specifically, they prevent sync_state() only callbacks from
being called on a device if one or more of its consumers haven't probed.
So, creating a SYNC_STATE_ONLY device link from an already probed

Add support for creating supplier-consumer links between fwnodes. It is
intended for internal use the driver core and generic firmware support
code (eg. Device Tree, ACPI), so it is simple by design and the API
provided is limited.

This reverts commit 716a7a2596.
The fw_devlink_pause/resume() APIs added by the commit being reverted
were a first cut attempt at optimizing boot time. But these APIs don't
fully solve the problem and are very fragile (can only be used for the
top level devices being added). This series replaces them with a much
better optimization that works for all device additions and also has the
benefit of reducing the complexity of the firmware (DT, EFI) specific
code and abstracting out common code to driver core.

The device_links_purge() function (called from device_del()) tries to
remove the links.needs_suppliers list entry, but it's using
list_del(), hence it doesn't initialize after the removal. This is OK
for normal cases where device_del() is called via device_destroy().
However, it's not guaranteed that the device object will be really
deleted soon after device_del(). In a minor case like HD-audio codec
reconfiguration that re-initializes the device after device_del(), it
may lead to a crash by the corrupted list entry.
As a simple fix, replace list_del() with list_del_init() in order to
make the list intact after the device_del() call.

It has been found that some users (like cpufreq-dt and others on LKML)
have abused the helper dev_pm_opp_get_opp_table() to create the OPP
table instead of just finding it, which is the wrong thing to do. This
routine was meant for OPP core's internal working and exposed the whole
functionality by mistake.
Change the scope of dev_pm_opp_get_opp_table() to only finding the
table. The internal helpers _opp_get_opp_table*() are thus renamed to
_add_opp_table*(), dev_pm_opp_get_opp_table_indexed() is removed (as we
don't need the index field for finding the OPP table) and so the only
user, genpd, is updated.
Note that the prototype of _add_opp_table() was already left in opp.h by
mistake when it was removed earlier and so we weren't required to add it
now.

It enables drivers to create an auxiliary_device and bind an

The MIPI SoundWire Device Class standard will define audio functionality
beyond the scope of the existing SoundWire 1.2 standard, which is limited
to the bus and interface.
The description is inspired by the USB Audio Class, with "functions",
"entities", "control selectors", "audio clusters". The main difference
with the USB Audio class is that the devices are typically on a motherboard
and descriptors stored in platform firmware instead of being retrieved
from the device.
The current set of devices managed in this patchset are conformant with the
SDCA 0.6 specification and require dedicated drivers since the descriptors
and platform firmware specification is not complete at this time. They do
however rely on the hierarchical addressing required by the SDCA standard.
Future devices conformant with SDCA 1.0 should rely on a class driver.
This series adds support for the hierarchical SDCA addressing and extends
regmap. It then provides 3 codecs for RT711-sdca headset codec, RT1316
amplifier and RT715-scda microphone codec.
Note that the release of this code before the formal adoption of the
SDCA 1.0 specification was formally endorsed by the MIPI Board to make
sure there is no delay for Linux-based support of this specification.

2.17.1
The SoundWire 1.1 specification only allowed for reads and writes of
bytes. The SoundWire 1.2 specification adds a new capability to
transfer "Multi-Byte Quantities" (MBQ) across the bus. The transfers
still happens one-byte-at-a-time, but the update is atomic.
For example when writing a 16-bit volume, the first byte transferred
is only taken into account when the second byte is successfully
transferred.
The mechanism is symmetrical for read and writes:
- On a read, the address of the last byte to be read is modified by
setting the MBQ bit
- On a write, the address of all but the last byte to be written are
modified by setting the MBQ bit. The address for the last byte relies
on the MBQ bit being cleared.
The current definitions for MBQ-based controls in the SDCA draft
standard are limited to 16 bits for volumes, so for now this is the
only supported format. An update will be provided if and when support
for 24-bit and 32-bit values is specified by the SDCA standard.
One possible objection is that this code could have been handled with
regmap-sdw.c. However this is a new spec addition not handled by every
SoundWire 1.1 and non-SDCA device, so there's no reason to load code
that will never be used.
Also in practice it's extremely unlikely that CONFIG_REGMAP would not
be selected with CONFIG_REGMAP_MBQ selected. However there's no
functional dependency between the two modules so they can be selected
separately.
