From 33b0f15434a40527e1e5278a63e91465ef4c7617 Mon Sep 17 00:00:00 2001 From: Anil Kumar Date: Mon, 12 Oct 2020 11:39:15 -0700 Subject: [PATCH] drivers/soundwire/alc711: Add Realtek ALC711 soundwire device Bug=None Test=Enabled the device on TGLY RVP and tested that the codec is reflected in SSDT. Checked sound card binding works and soundwire drivers are enabled in kernel.
