[PATCH v4 07/10] ASoC: dt-bindings: clarify areg-supply documentation

Posted by Sascha Hauer 3 weeks, 6 days ago

From: Emil-Juhl <juhl.emildahl@gmail.com>

The documentation for areg-supply could cause confusion mainly in terms
of the relationship between AREG and AVDD.
According to the datasheet[1] the AREG can be one of two cases:

1) an external 1.8V supply
2) generated by an internal regulator (hence a 1.8V output)
