[PATCH v2 0/4] ASoC: qcom: Fix AudioReach TDM review findings

From: Prasad Kumpatla

Date: Tue Aug 18 2026 - 04:53:56 EST


Address review findings for the recently merged AudioReach TDM backend
support.

The first patch fixes a typo in the newly added QAIF clock ID names by
renaming the LAPSS-prefixed identifiers to LPASS and updating all
corresponding in-tree users.

The remaining patches address issues identified in the AudioReach TDM
configuration and machine-driver paths:

- Zero-initialize AudioReach module configuration structures so
unspecified slot parameters correctly fall back to topology defaults.

- Distinguish between missing TDM configuration and malformed TDM slot
properties by using separate return codes, preventing valid DT
configuration errors from being silently ignored.

- Fix sc8280xp TDM hw_params error handling by properly distinguishing
optional and invalid TDM slot configurations and propagating errors
accordingly.

All issues were reported by Sashiko.

Changes in v2:
- Folded patches 1 and 2 into a single patch so the QAIF clock ID
rename and its users are updated together.
- Avoid an intermediate build failure and keep the series buildable
on a per-patch basis.
