soundwire: intel_auxdevice: add cs42l45 codec to wake_capable_list

2026-03-04T12:20:38+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

2026-02-26T23:01:24+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.

include/sdw_type.h provides the function is_sdw_slave() which requires sdw_slave_type. But sdw_slave_type was not exported.

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

2026-01-13T11:26:03+00:00

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: introduce BPT section

2025-12-08T07:07:27+00:00

Currently we send a BRA message with a start address with continuous registers in a BPT stream. However, a codec may need to write different register sections shortly. Introduce a register section in struct sdw_btp_msg which contain register start address, length, and buffer. This commit uses only 1 section for each BPT message. And we need to add up all BPT section length and check if it reach maximum BPT bytes. No function changes.
