From fbea9f34a247dbafb60bca4967e0952466793a22 Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Thu, 7 Jul 2022 14:41:43 +0200 Subject: [PATCH] ASoC: Intel: avs: Assign I2S gateway when parsing topology For formatted port - ssp%d - descriptions to have an effect, copier module templates need to be updated with specified port value. This value is later propagated to the firmware when module instances are being instantiated.
