soundwire: intel: move to auxiliary bus

2021-06-14T04:42:26Z

Now that the auxiliary_bus exists, there's no reason to use platform devices as children of a PCI device any longer. This patch refactors the code by extending a basic auxiliary device with Intel link-specific structures that need to be passed between controller and link levels. This refactoring is much cleaner with no need for cross-pointers between device and link structures. Note that the auxiliary bus API has separate init and add steps, which requires more attention in the error unwinding paths. The main loop needs to deal with kfree() and auxiliary_device_uninit() for the current iteration before jumping to the common label which releases everything allocated in prior iterations.

soundwire: Add generic bandwidth allocation algorithm

2020-09-18T12:18:51Z

This algorithm computes bus parameters like clock frequency, frame shape and port transport parameters based on active stream(s) running on the bus. Developers can also implement their own .compute_params() callback for specific resource management algorithm, and set if before calling sdw_add_bus_master() Credits: this patch is based on an earlier internal contribution by Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah. All hard-coded values were removed from the initial contribution to use BIOS information instead.

soundwire: qcom: add support for SoundWire controller

2020-01-14T06:27:47Z

Qualcomm SoundWire Master controller is present in most Qualcomm SoCs either integrated as part of WCD audio codecs via slimbus or as part of SOC I/O. This patchset adds support to a very basic controller which has been tested with WCD934x SoundWire controller connected to WSA881x smart speaker amplifiers.

soundwire: intel: remove X86 dependency

This is not needed and may generate unmet dependencies when COMPILE_TEST is used for SOF. ACPI is required, and should be tested when selecting this option.

Now devicetree is supported for probing soundwire as well. On platforms built with !ACPI !OF (ie s390x) the device still cannot be probed and gives a build warning.
