Add regulators property to enable the use of the VCM output, referenced here as vcm-output, by any other device. Acked-by: Conor Dooley Signed-off-by: Jonathan Santos --- v5 Changes: * removed `regulator-min-microvolt` and `regulator-max-microvolt`. v4 Changes: * replace "vcm_output" property name for "vcm-output". v3 Changes: * VCM is now provided as a regulator within the device, instead of a custom property. v2 Changes: * New patch in v2. --- .../bindings/iio/adc/adi,ad7768-1.yaml | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/Documentation/devicetree/bindings/iio/adc/adi,ad7768-1.yaml b/Documentation/devicetree/bindings/iio/adc/adi,ad7768-1.yaml index 6b318f05a69f..e4c433b16e55 100644 --- a/Documentation/devicetree/bindings/iio/adc/adi,ad7768-1.yaml +++ b/Documentation/devicetree/bindings/iio/adc/adi,ad7768-1.yaml @@ -70,6 +70,19 @@ properties: in any way, for example if the filter decimation rate changes.
