8eb5d7ad - soundwire: cadence: add BTP/BRA helpers to format data

Thu, 27 Feb 2025 14:06:08 +0000

soundwire: cadence: add BTP/BRA helpers to format dataThe Cadence IP expects a specific format (detailed in theDocumentation). Add helpers to copy the data into the DMA buffer.The crc8 table is for now only used by the Cadence driver. This tablemight be moved to a common module at a later point if needed by othercontroller implementations.Signed-off-by: Pierre-Louis Bossart Signed-off-by: Bard Liao Reviewed-by: Péter Ujfalusi Reviewed-by: Liam Girdwood Reviewed-by: Ranjani Sridharan Tested-by: shumingf@realtek.comLink: https://lore.kernel.org/r/20250227140615.8147-10-yung-chuan.liao@linux.intel.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/soundwire/Kconfig

29a269c6 - soundwire: intel: move to auxiliary bus

Tue, 11 May 2021 05:21:32 +0000

soundwire: intel: move to auxiliary busNow that the auxiliary_bus exists, there's no reason to use platformdevices as children of a PCI device any longer.This patch refactors the code by extending a basic auxiliary devicewith Intel link-specific structures that need to be passed betweencontroller and link levels. This refactoring is much cleaner with noneed for cross-pointers between device and link structures.Note that the auxiliary bus API has separate init and add steps, whichrequires more attention in the error unwinding paths. The main loopneeds to deal with kfree() and auxiliary_device_uninit() for thecurrent iteration before jumping to the common label which releaseseverything allocated in prior iterations.Signed-off-by: Pierre-Louis Bossart Reviewed-by: Guennadi Liakhovetski Reviewed-by: Ranjani Sridharan Signed-off-by: Bard Liao Link: https://lore.kernel.org/r/20210511052132.28150-1-yung-chuan.liao@linux.intel.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/soundwire/Kconfig
