From af2c06c41970eb0110a03696fd7f8f07854719db Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Wed, 17 Oct 2018 00:38:08 -0700 Subject: [PATCH] ASoC: dt-binding: Add bindings for Allwinner A64 codec's analog path controls The internal codec on Allwinner A64 is split into 2 parts. The analog path controls are routed through an embedded custom register bus accessed through the PRCM block just as on A23/A33/H3. Add a binding for this hardware.
