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) [1] https://www.ti.com/lit/ds/symlink/tlv320adc5140.pdf Signed-off-by: Emil-Juhl Signed-off-by: Sascha Hauer Acked-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260113-sound-soc-codecs-tvl320adcx140-v4-7-8f7ecec525c8@pengutronix.de Signed-off-by: Mark Brown --- diff --git a/Documentation/devicetree/bindings/sound/ti,tlv320adcx140.yaml b/Documentation/devicetree/bindings/sound/ti,tlv320adcx140.yaml index 876fa97bfbcdd..b34ea78243603 100644 --- a/Documentation/devicetree/bindings/sound/ti,tlv320adcx140.yaml +++ b/Documentation/devicetree/bindings/sound/ti,tlv320adcx140.yaml @@ -41,8 +41,8 @@ properties: areg-supply: description: | - Regulator with AVDD at 3.3V.
