soundwire: amd: Add support for AMD Manager driver

2023-04-12T10:00:35+00:00

AMD ACP(v6.x) IP block has two SoundWire manager devices.
Add support for
  - Manager driver probe & remove sequence
  - Helper functions to enable/disable interrupts,
    Initialize sdw manager, enable sdw pads
  - Manager driver sdw_master_ops & port_ops callbacks

soundwire: intel: add abstraction for cmdsync check

2023-03-15T13:54:02+00:00

If we add one more callback, we can have common bank switch sequences
between old and new hardware: the only difference is where the CMDSYNC
register is located.

soundwire: intel: add sync_arm/sync_go to ops

2023-03-15T13:54:02+00:00

The bus start/stop sequences can be reused between platforms if we add
a couple of new callbacks. In following patches the code will be moved to
a shared file.

Merge tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2023-02-24T20:58:55+00:00

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.
