[PATCH v9 8/8] arm64: dts: allwinner: a64: enable sound on Pinebook

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vasily Khoruzhick <anarsoul@xxxxxxxxx>

The Pinebook has a headphone jack tied to the HP headphone output of
the SoC, and internal speakers connected to the LINEOUT of the SoC,
through a standalone amplifier.

This commit enables I2S, digital and analog parts of audio codec on
Pinebook, along with a device node for the external amplifier.

[wens@xxxxxxxx: dropped headphone_amp; added headphone amp regulator supply;
		fixed speaker_amp node name and sound-name-prefix name]
