soundwire: intel_auxdevice: add cs42l45 codec to wake_capable_list

2026-03-04T12:20:32+00:00

[ Upstream commit f87e5575a6bd1925cd55f500b61b661724372e5f ] Add cs42l45 to the wake_capable_list because it can generate jack events whilst the bus is stopped.

soundwire: intel_ace2x: add SND_HDA_CORE dependency

2026-02-26T22:59:32+00:00

[ Upstream commit dc3a6a942e9ee3f18560bfcb16c06bb94f37fabf ] The ace2x driver can optionally use the HDA infrastructure, but can still build without that. However, with SND_HDA_CORE=m and SND_HDA_ALIGNED_MMIO=y, it fails to link as built-in: aarch64-linux-ld: drivers/soundwire/intel_ace2x.o: in function `intel_shim_wake': intel_ace2x.c:(.text+0x2518): undefined reference to `snd_hdac_aligned_read' aarch64-linux-ld: intel_ace2x.c:(.text+0x25d4): undefined reference to `snd_hdac_aligned_read' aarch64-linux-ld: intel_ace2x.c:(.text+0x268c): undefined reference to `snd_hdac_aligned_write' Add a Kconfig dependency that forces the soundwire driver to be a loadable module if necessary.

soundwire: bus: fix off-by-one when allocating slave IDs

2026-01-23T10:21:22+00:00

[ Upstream commit 12d4fd9a657174496677cff2841315090f1c11fc ] ida_alloc_max() interprets its max argument as inclusive. Using SDW_FW_MAX_DEVICES(16) therefore allows an ID of 16 to be allocated, but the IRQ domain created for the bus is sized for IDs 0-15. If 16 is returned, irq_create_mapping() fails and the driver ends up with an invalid IRQ mapping. Limit the allocation to 0-15 by passing SDW_FW_MAX_DEVICES - 1.

soundwire: bus: add sdw_slave_get_current_bank helper

2025-09-18T21:24:27+00:00

There has been 2 instances of this helper in codec drivers, it does not make sense to keep duplicating this part of code. Lets add a helper sdw_get_current_bank() for codec drivers to use it.

soundwire: bus: Drop dev_pm_domain_detach() call

2025-09-01T17:17:09+00:00

Starting with commit f99508074e78 ("PM: domains: Detach on device_unbind_cleanup()"), there is no longer a need to call dev_pm_domain_detach() in the bus remove function. The device_unbind_cleanup() function now handles this to avoid invoking devres cleanup handlers while the PM domain is powered off, which could otherwise lead to failures as described in the above-mentioned commit. Drop the explicit dev_pm_domain_detach() call and rely instead on the flags passed to dev_pm_domain_attach() to power off the domain.
