Subject[PATCH 3/4] arm64: DTS: allwinner: a64: Enable audio on Teres-I
Date
From: Harald Geyer <harald@ccbib.org>

The TERES-I has internal speakers (left, right), internal microphone
and a headset combo jack (headphones + mic).

The headphone lines are multiplexed with the debug console.
The headphone and mic detect lines of the A64 are connected properly,
but AFAIK currently unsupported by the driver.

originally: patchwork.kernel.org/patch/10792589

Removed the questionable issues, leaving the unchallenged parts.
