However, I see it actually has multiple power supplies, so perhaps this needs more thought first. One other thing inline that I 'might' 'fix' depending on what is later in the series. > > .../bindings/iio/adc/ti-ads124s08.txt | 23 +++++++++++++++++++ > 1 file changed, 23 insertions(+) > create mode 100644 Documentation/devicetree/bindings/iio/adc/ti-ads124s08.txt > > diff --git a/Documentation/devicetree/bindings/iio/adc/ti-ads124s08.txt b/Documentation/devicetree/bindings/iio/adc/ti-ads124s08.txt > new file mode 100644 > index 000000000000..6993e76e61c6 > --- /dev/null > +++ b/Documentation/devicetree/bindings/iio/adc/ti-ads124s08.txt > @@ -0,0 +1,23 @@ > +* Texas Instruments' ads124s08 and ads124s06 ADC chip > + > +Required properties: > + - compatible: Should be "ti,ads124s08" or "ti,ads124s06" One per line. - compatible: Should be one of "ti..." "ti..." It's easier to add other parts with out having to rewrite the sentence to cover the now more than 2 case. If that's all I find in the series, I'll just fix it up when applying.
