soundwire: bus: Make IRQ handling conditionally built

2023-09-21T09:31:33+00:00

SoundWire has provisions for a simple callback for the IRQ handling so has no hard dependency on IRQ_DOMAIN, but the recent addition of IRQ handling was causing builds without IRQ_DOMAIN to fail. Resolve this by moving the IRQ handling into its own file and only add it to the build when IRQ_DOMAIN is included in the kernel.

soundwire: intel_ace2x: add empty new ops for LunarLake

2023-05-27T10:36:44+00:00

The register map and programming sequences for the ACE2.x IP are completely different and need to be abstracted with a different set of callbacks. This initial patch adds a new file, follow-up patches will add each required callback.

soundwire: intel: move bus common sequences to different file

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

Now that the bus start/stop/clock_stop sequences use the ops, we can move them to a different file to reuse them. Note that we could in theory remove the abstraction for all those sequences and directly call the functions in intel_auxdevice.c. To allow for more flexibility and have means to special-case new platforms, we decided to keep the abstraction. If in time it becomes clear there is no benefit the abstraction will be simplified.

The auxdevice layer is completely generic, it should be split from intel.c which is only geared to the 'cnl' hw_ops now.

soundwire: Intel: introduce DMI quirks for HP Spectre x360 Convertible

2021-03-22T12:03:10+00:00

HP Spectre x360 Convertible devices expose invalid _ADR fields in the DSDT, which prevents codec drivers from probing. A possible solution is to override the DSDT, but that's just too painful for users. This patch suggests a simple DMI-based quirk to remap the existing invalid ADR information into valid ones.

soundwire: Add generic bandwidth allocation algorithm

2020-09-18T12:18:51+00:00

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.

It's not clear why we have two modules for the Intel controller/master support when there is a single Kconfig. This adds complexity for no good reason, the two parts need to work together anyways.
