ASoC: amd: ps: fix the pcm device numbering for acp pdm dmic

2026-05-23T11:08:54+00:00

[ Upstream commit 3666dc0c47c399695d01fde7c36e08b14f834fa0 ] Fixed PCM device numbering is required for acp pdm dmic pcm device to have a common UCM changes. Set the 'use_dai_pcm_id' flag true in acp pdm dma driver for acp 6.3 platform. This will fix the pcm device numbering based on dai_link->id.

ASoC: amd: name back to pcm_new()/pcm_free()

2026-05-23T11:08:54+00:00

[ Upstream commit fe33a69681e343999e18893f97bb6cd99b883992 ] We have been used pcm_new()/pcm_free(), but switched to pcm_construct()/pcm_destruct() to use extra parameters [1]. pcm_new()/free() had been removed [2], but each drivers are still using such function naming. Let's name back to pcm_new()/pcm_free() again.

ASoC: amd: ps: Fix missing leading zeros in subsystem_device SSID log

2026-04-01T12:08:47+00:00

Ensure that subsystem_device is printed with leading zeros when combined with subsystem_vendor to form the SSID. Without this, devices with upper bits unset may appear to have an incorrect SSID in the debug output.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

ASoC: amd: ps: Propagate the PCI subsystem Vendor and Device IDs

2025-10-20T01:39:23+00:00

Extend the ACP machine driver to propagate the PCI subsystem Vendor and Device IDs so that they may be subsequently used as an SSID.

ASoC: amd: ps: fix for soundwire failures during hibernation exit sequence

2025-06-23T13:20:29+00:00

During the hibernate entry sequence, ACP registers will be reset to default values and acp ip will be completely powered off including acp SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable register is not restored along with pad pulldown control register value, then SoundWire manager links won't be powered on correctly results in peripheral register access failures and completely audio function is broken. Add code to store the acp SoundWire pad keeper enable register and acp pad pulldown ctrl register values before entering into suspend state and restore the register values during resume sequence based on condition check for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1 platforms.

ASoC: amd: ps: fix for irq handler return status

2025-04-30T23:22:36+00:00

If any Soundwire manager interrupt is reported, and wake interrupt is not reported, in this scenario irq_flag will be set to zero, which results in interrupt handler return status as IRQ_NONE. Add new irq flag 'wake_irq_flag' check for SoundWire wake interrupt handling to fix incorrect irq handling return status.

ASoC: amd: Convert to RUNTIME_PM_OPS() & co

2025-03-17T10:15:04+00:00

Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together with pm_ptr(), which allows us dropping ugly __maybe_unused attributes. This optimizes slightly when CONFIG_PM is disabled, too.
