the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

Subject: [PATCH] ASoC: dt-bindings: sun50i-codec-analog: Add headphone amp
regulator supply

On the Allwinner A64 SoC, the audio codec has a built-in headphone
amplifier. This amplifier has a power supply separate from the rest of
the analog audio circuitry.

Add a regulator supply property to handle this.
