If there are no other changes, I can amend this text whilst applying. Something lie: The asm330lhhx supports a subset of the features and functionality provided by the asm330lhhxg1 via identical interfaces and so is a suitable fallback compatible. As normal for bindings we shouldn't talk about the driver though what we really care about here is that the driver will never support functionality for the fallback part that doesn't apply for the more advanced part (because there isn't any!) > > Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> > --- > Documentation/devicetree/bindings/iio/imu/st,lsm6dsx.yaml | 3 +++ > 1 file changed, 3 insertions(+) > > diff --git a/Documentation/devicetree/bindings/iio/imu/st,lsm6dsx.yaml b/Documentation/devicetree/bindings/iio/imu/st,lsm6dsx.yaml > index 28b667a9cb76..7ba3de66a2e1 100644 > --- a/Documentation/devicetree/bindings/iio/imu/st,lsm6dsx.yaml > +++ b/Documentation/devicetree/bindings/iio/imu/st,lsm6dsx.yaml > @@ -49,6 +49,9 @@ properties: > - items: > - const: st,asm330lhb > - const: st,asm330lhh > + - items: > + - const: st,asm330lhhxg1 > + - const: st,asm330lhhx > > reg: > maxItems: 1

You need to explain why "st,lsm6dsr" is not needed as a fallback or you need your original change with "st,lsm6dsr" added on the end. (And group it next to the original entry, not at the end.) The question to ask is whether software that only understands what "st,lsm6dsr" is will work with this newer device. Rob

Add device bindings for asm330lhhxg1 IMU sensor. Use asm330lhhx as fallback device for asm330lhhxg1 since it implements all the features currently supported by asm330lhhxg1.
