From 68b2fc33e6798025af039dee0c936c43bdd7d3c0 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 6 Feb 2020 23:49:27 -0600 Subject: [PATCH 095/464] arm64: dts: sun50i-a64-pinephone: Add support for Bluetooth audio The PinePhone has a Bluetooth chip with its PCM interface connected to AIF3. Add the DAI link so headeset audio can be routed in hardware. Even though the link is mono, configuring the link for 2 slots is required for compatibility with AIF2, which uses a single 32-bit slot, and which shares its clock dividers with AIF3. Using equal clock frequencies allows the modem and headset to be used at the same time.
