The analog path controls are routed through an embedded custom register bus accessed through the PRCM block. The SoCs share a common set of inputs, outputs, and audio paths. The following table lists the differences. ---------------------------------------- | Feature \ SoC | A23 | A33 | H3 | ---------------------------------------- | Headphone | v | v | | ---------------------------------------- | Line Out | | | v | ---------------------------------------- | Phone In/Out | v | v | | ---------------------------------------- Add a binding for this hardware.
