Add a SoundWire machine table entry for the LG Gram Pro 2026
(16Z90U-KU7BK), which has an unusual configuration:

  sdw:0:1:025d:1320:01   single stereo RT1320 SmartAmp on link 1
  sdw:0:3:025d:0713:01   RT713 jack/headset codec on link 3

Existing rt713-rt1320 boards have two RT1320 amps on different links
("link_mask = BIT(1) | BIT(2) | BIT(3)"). The LG Gram uses a single
stereo RT1320 chip, so the new entry uses "link_mask = BIT(1) |
BIT(3)" with the existing rt1320_1_group2_adr structure, leaving the
two-channel routing to the topology.

The RT713 on this board does not expose a SMART_MIC function in
ACPI, so the .machine_check callback used by the existing entries
(snd_soc_acpi_intel_sdca_is_device_rt712_vb) would reject this
board. Drop machine_check for the new entry; speaker output and
the headset jack do not depend on the SMART_MIC presence check.

The corresponding topology source has been submitted to the SOF
project at https://github.com/thesofproject/sof/pull/10760 . The
generated sof-ptl-rt713-l3-rt1320-l1-2ch.tplg and
nhlt-sof-ptl-rt713-l3-rt1320-l1.bin will follow in linux-firmware
once that lands.

Tested on Ubuntu 26.04 with kernel 7.0.0-15: speaker (RT1320
stereo), headphone jack with auto-routing, headset mic, and the
internal NHLT DMIC array all work via the UCM HiFi profile.

Thanks!

[1/1] ASoC: Intel: soc-acpi: add LG Gram 16Z90U RT713 + single RT1320 quirk
      https://git.kernel.org/broonie/sound/c/d714913b61d5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
