Subject: [PATCH 097/391] 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.
