From 28c0cf16b3083566cd96b60d3cedbe69b79a8e5b Mon Sep 17 00:00:00 2001 From: Garrett Giordano Date: Thu, 4 Apr 2024 11:42:50 -0700 Subject: [PATCH] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Add Audio Codec The Audio Codec runs over the MCASP (Multichannel Audio Serial Port). Add pinmux for the Audio Reference Clock and MCASP2. Add DT nodes for Audio Codec, MCASP2, VCC 1v8 and VCC 3v3 regulators. Additionally, create a sound node that connects our sound card and the MCASP2.
