From 0723affa1bee50c3bd7ca00e00dee07fcef224b8 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 20 Oct 2025 16:55:09 +0100 Subject: ASoC: SDCA: Add completion for FDL start and stop Add some completions and a helper function to allow other parts of the system to wait for FDL to complete. The sdca_fdl_sync() function will wait until it completes a full time out without a new FDL request happening, this ensures that even parts requiring multiple rounds of FDL should be fully downloaded before the driver boot continues.
