To be squashed into v10 if accepted. Signed-off-by: Jacopo Mondi --- While fixing Rob's reported bug on v9 I realized thanks to a dt_binding_check warning that the i2c-mux child nodes where under-specified. This fixup epxands the i2c-mux child nodes description and updates the example to match our currently-out-of-tree DTS files for GMSL platforms. dt_binding_check still reports a warning: Documentation/devicetree/bindings/media/i2c/maxim,max9286.example.dt.yaml: camera@51: reg: [[81, 97]] is too short Documentation/devicetree/bindings/media/i2c/maxim,max9286.example.dt.yaml: camera@52: reg: [[82, 98]] is too short Documentation/devicetree/bindings/media/i2c/maxim,max9286.example.dt.yaml: camera@53: reg: [[83, 99]] is too short Documentation/devicetree/bindings/media/i2c/maxim,max9286.example.dt.yaml: camera@54: reg: [[84, 100]] is too short Which I was not able to silence. --- .../bindings/media/i2c/maxim,max9286.yaml | 86 +++++++++++++++++-- 1 file changed, 77 insertions(+), 9 deletions(-) -- 2.26.2 diff --git a/Documentation/devicetree/bindings/media/i2c/maxim,max9286.yaml b/Documentation/devicetree/bindings/media/i2c/maxim,max9286.yaml index f9d3e5712c59..d9bd19caed2f 100644 --- a/Documentation/devicetree/bindings/media/i2c/maxim,max9286.yaml +++ b/Documentation/devicetree/bindings/media/i2c/maxim,max9286.yaml @@ -130,9 +130,7 @@ properties: description: | Each GMSL link is modelled as a child bus of an i2c bus multiplexer/switch, in accordance with bindings described in - Documentation/devicetree/bindings/i2c/i2c-mux.txt.
