ASoC: qcom: add Surface Pro 11 TX DMIC capture

[ooaklee]

Summary

• select the validated DIV4 direct-DMIC clocking on Surface Pro 11
• let the Denali TX macro request the two direct-DMIC pad clocks owned by the VA macro
• add the regular two-channel TX_CODEC_DMA_TX_3 capture route while retaining the existing low-power VA path

Dependency and status

This PR targets jg/ubuntu-qcom-x1e-7.2.y directly. It follows the Denali baseline in #82, the QSPI/touch core in #83, the pen ABI topic, and the split camera topics:

• pen ABI prerequisite: Input: mshw0485: add opt-in pen userspace interfaces #84
• final camera-graph prerequisite: arm64: dts: qcom: x1e80100-denali-oled: enable front camera #87

The branch itself is based directly on the release branch, so it does not merge those prerequisite heads or the broad -sp11 staging branch. It also does not replay the correction merged through #81.

This PR is a draft until the exact branch has passed the SP11 capture and non-SP11 audio checks below. Protected speaker playback remains a separate audio topic and is not required by this microphone-capture path.

Containment

• the alternate 4.8 MHz validation and DIV4 selection are gated by the microsoft,denali root compatible
• the VA-to-TX clock broker is used only by the exact Denali two-channel DMIC0/DMIC1 route
• existing VA capture remains present for low-power use and comparison
• other LPASS machines retain the existing VA divider, TX event handling, and direct-DMIC ownership
• the board change is limited to the common Denali description and does not add the route to unrelated X1E devices
• no speaker-protection runtime, PA profile, diagnostic ABI, global readiness state, or module parameter is included

Provenance

The divider and shared-clock commits preserve Co-authored-by: geoca <272055834+geocausa@users.noreply.github.com> from @geocausa's focused source patches, link to their immutable revisions, and append Signed-off-by: Leon Silcott <leon@boasi.io>. The Denali route commit is authored and signed by Leon Silcott.

All three commits also link back to the relevant integration commits, including 58e36b1acb04, so the contributor history remains discoverable without carrying the original broad commits wholesale.

Validation

• git diff --check 032e174490d2..HEAD
• strict checkpatch for all three commits
• ARM64 ubuntu_x1e_defconfig W=1 builds of the affected LPASS common, VA-macro, and TX-macro objects
• successful builds of both Surface Pro 11 Denali device trees
• source audit confirms that the changed divider and cross-macro clock requests are Denali-gated
• source audit confirms no protected-playback runtime, userspace ABI, diagnostic control, or module parameter is present

Hardware checks still required

• boot this exact branch on an X1E Surface Pro 11
• record from the regular two-channel TX path at 48 kHz and verify both microphone channels
• compare the existing VA capture path and confirm it remains usable
• repeat open/close, capture, suspend/resume, and capture-after-resume cycles
• check kernel logs for LPASS clock, DAI, AudioReach, or underrun errors
• run playback and capture smoke tests on at least one non-SP11 X1E device to confirm the shared LPASS paths retain their existing behavior
