Pull driver core updates from Greg KH:
 "Here is the large set of driver core changes for 6.3-rc1.

  There's a lot of changes this development cycle, most of the work
  falls into two different categories:

   - fw_devlink fixes and updates. This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.

   - driver core changes to work to make struct bus_type able to be
     moved into read-only memory (i.e. const) The recent work with Rust
     has pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only
     making things safer overall. This is the contuation of that work
     (started last release with kobject changes) in moving struct
     bus_type to be constant. We didn't quite make it for this release,
     but the remaining patches will be finished up for the release after
     this one, but the groundwork has been laid for this effort.

  Other than that we have in here:

   - debugfs memory leak fixes in some subsystems

   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.

   - cacheinfo rework and fixes

   - Other tiny fixes, full details are in the shortlog

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

[ Geert Uytterhoeven points out that that last sentence isn't true, and
  that there's a pending report that has a fix that is queued up - Linus ]

soundwire: cadence: further simplify low-level xfer_msg_defer() callback

2023-01-31T14:31:52+00:00

The message pointer is already stored in the bus->defer structure, not
need to pass it as an argument.

soundwire: cadence: use directly bus sdw_defer structure

2023-01-31T14:29:21+00:00

Copying the bus sdw_defer structure into the Cadence internals leads
to using stale pointers and kernel oopses on errors. It's just simpler
and safer to use the bus sdw_defer structure directly.

soundwire: stream: Add specific prep/deprep commands to port_prep callback

2023-01-31T12:10:45+00:00

Currently, port_prep callback only has commands for PRE_PREP, PREP,
and POST_PREP, which doesn't directly say whether this is for a
prepare or deprepare call. Extend the command list enum to say
whether the call is for prepare or deprepare aswell.

Also remove SDW_OPS_PORT_PREP from sdw_port_prep_ops as this is unused,
and update this enum to be simpler and more consistent with enum
sdw_clk_stop_type.

Note: Currently, the only users of SDW_OPS_PORT_POST_PREP are codec
drivers sound/soc/codecs/wsa881x.c and sound/soc/codecs/wsa883x.c, both
of which seem to assume that POST_PREP only occurs after a prepare,
even though it would also have occurred after a deprepare. Since it
doesn't make sense to mark the port prepared after a deprepare, changing
the enum to separate PORT_DEPREP from PORT_PREP should make the check
for PORT_PREP in those drivers be more logical.

soundwire: bus: Remove unused reset_page_addr() callback

2023-01-31T12:06:14+00:00

A previous patch removed unnecessary zeroing of the page registers
after a paged transaction, so now the reset_page_addr callback is
unused and can be removed.

driver core: make struct device_type.uevent() take a const *

2023-01-27T12:45:36+00:00

The uevent() callback in struct device_type should not be modifying the
device that is passed into it, so mark it as a const * and propagate the
function signature changes out into all relevant subsystems that use
this callback.

soundwire: Provide build stubs for common functions

2023-01-09T16:16:27+00:00

Provide stub functions when CONFIG_SOUNDWIRE is not set for functions
that are quite likely to be used from common code on devices supporting
multiple control buses.

The commit 167790abb90f ("soundwire: export sdw_write/read_no_pm
functions") exposed the single byte no_pm versions of the IO functions
that can be used without touching PM, export the multi byte no_pm
versions for the same reason.

soundwire: enable optional clock registers for SoundWire 1.2 devices

2023-01-09T16:07:40+00:00

The bus supports the mandatory clock registers for SDCA devices, these
registers can also be optionally supported by SoundWire 1.2 devices
that don't follow the SDCA class specification.
