Subject: ARM: dts: am335x-evm: Correct the regulators for the audio codec
From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>
commit 4f96dc0a3e79ec257a2b082dab3ee694ff88c317 upstream.
Correctly map the regulators used by tlv320aic3106.
Both 1.8V and 3.3V for the codec is derived from VBAT via fixed regulators.
