Merge tag 'soundwire-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire
Pull soundwire updates from Vinod Koul:
"This is a small update which features a bit of core changes and driver
updates in Intel and cadence driver.
Core:
- sdw_transfer_defer() API change to drop an argument
- Reset page address rework
- Export sdw_nwrite_no_pm and sdw_nread_no_pm APIs
Drivers:
- Cadence and related intel driver updates for FIFO handling and low
level msg transfers"
* tag 'soundwire-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire:
soundwire: cadence: further simplify low-level xfer_msg_defer() callback
soundwire: cadence: use directly bus sdw_defer structure
soundwire: bus: remove sdw_defer argument in sdw_transfer_defer()
soundwire: stream: use consistent pattern for freeing buffers
soundwire: bus: Remove unused reset_page_addr() callback
soundwire: bus: Don't zero page registers after every transaction
soundwire: bus_type: Avoid lockdep assert in sdw_drv_probe()
soundwire: stream: Move remaining register accesses over to no_pm
soundwire: debugfs: Switch to sdw_read_no_pm
soundwire: Provide build stubs for common functions
soundwire: bus: export sdw_nwrite_no_pm and sdw_nread_no_pm functions
soundwire: cadence: remove unused sdw_cdns_master_ops declaration
soundwire: enable optional clock registers for SoundWire 1.2 devices
ASoC/soundwire: remove is_sdca boolean property
soundwire: cadence: Drain the RX FIFO after an IO timeout
soundwire: cadence: Remove wasted space in response_buf
soundwire: cadence: Don't overflow the command FIFOs
soundwire: intel: remove DAI startup/shutdown
