From 264d3d776fb1a428706b0ca0f679bbed876fe7c9 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 7 Jul 2025 13:41:54 +0100 Subject: ASoC: SDCA: Add a helper to get the SoundWire port number Add a helper function to extract the SoundWire hardware port number from the SDCA DataPort Selector Control. Typically this would be called from hw_params() and used to call sdw_stream_add_slave().
