[PATCH 00/13] ASoC: amd: acp: ACP7.B/7.F SoundWire machine driver support

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

This series extends the AMD ACP SoundWire machine driver to support
ACP7.B and ACP7.F platforms, adds ACPI machine tables for SoundWire
codec configurations, and fixes several issues in the SOF SoundWire
machine driver.

Patches 1-2 add the infrastructure for ACP7.B/7.F SoundWire support.
Patch 1 adds PCI revision constants and the ACP7X_SDW_MAX_LINKS (4)
constant to soc_amd_sdw_common.h, and switches mc_probe() to set
max_sdw_links based on PCI revision. Patch 2 adds the get_acp7x_cpu_pin_id()
function and hooks it into create_sdw_dailink() for ACP7.B/7.F alongside
the existing ACP63 and ACP70 paths.

Patches 3-7 address DMIC DAI link selection and components string
handling for ACP7.B/7.F platforms. Patch 3 fixes the PDM quirk
evaluation order: ASOC_SDW_ACP_DMIC1 was checked before dmi_check_system()
and quirk_override were applied, making the fallback dead code. It also
corrects the condition to use else if, since only one PDM controller
can be active at a time. Patch 4 adds ASOC_SDW_ACP_DMIC1 to log_quirks()
for boot-time diagnostics. Patch 5 extends the DMIC DAI link enable
condition to also check amd_ctx->pdm_sel so that ACPI-selected PDM
controllers on ACP7.B/7.F are handled without requiring a DMI quirk.
Patch 6 moves the ignore_internal_dmic gate to the DMIC enable condition,
removing dead code and demoting a spurious dev_warn to dev_dbg. Patch 7
appends the DMIC components string to card->components in mc_probe()
when a DMIC link will be registered, mirroring the condition used in
sof_card_dai_links_create().

Patch 8 propagates the PCI subsystem vendor and device IDs to the ALSA
card via snd_soc_card_set_pci_ssid() for correct device identification.

Patch 9 fixes a pre-existing typo: the MODULE_AUTHOR macro call was
missing the closing '>' in the email address.

Patches 10-13 add ACPI machine tables and wire them into the SOF
descriptors. Patch 10 introduces amd-acp7x-acpi-match.c with four
ACP7.F SoundWire machine entries covering RT721+RT1320 (L0+L3),
RT721+RT1320 (L0+L1), standalone RT721, and standalone RT722. Patch 11
registers the ACP7.F SoundWire table as alt_machines in the ACP7.F SOF
descriptor. Patch 12 adds a single ACP7.B entry for RT721 (L0) + RT1320
(L3). Patch 13 registers the ACP7.B SoundWire table as alt_machines in
the ACP7.B SOF descriptor.

This patch series has dependency on the following SOF patch series:
