From a2417b6c0f9c3cc914c88face9abd6e9b9d76c00 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Fri, 23 Feb 2024 18:51:10 +0100 Subject: ASoC: meson: axg-spdifin: use max width for rate detection Use maximum width between 2 edges to setup spdifin thresholds and detect the input sample rate. This comes from Amlogic SDK and seems to be marginally more reliable than minimum width. This is done to align with a future eARC support. No issue was reported with minimum width so far, this is considered to be an update so no Fixes tag is set.
