From 439c43d9628ee38c72fdc5933f7b6091461441b6 Mon Sep 17 00:00:00 2001 From: Vijendar Mukunda Date: Tue, 13 Oct 2026 21:11:40 +0530 Subject: [PATCH] ASoC: SOF: amd: propagate pdm_sel to SDW machine driver via mach->pdata When amd_sof_sdw_machine_select() returns a SoundWire machine, it did not carry the PDM controller selection to the machine driver. Without this, acp-sdw-sof-mach.c cannot configure the correct DMIC DAI link for ACP7.B/7.F platforms. Allocate amd_pdm_pdata and assign it to mach->pdata in the SDW machine select return path when acp_data->pdm_sel is non-zero, mirroring the existing handling in amd_sof_machine_select().
