Dan seems to have trouble running get_maintainers.pl and Cc'ing the DT 
list. Running 'make dt_binding_check' also seems to be a problem. Now 
linux-next has these warnings:

/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/sound/tlv320adcx140.example.dt.yaml: codec at 4c: ti,gpi-config:0:0: 4 is greater than the maximum of 1

/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/sound/tlv320adcx140.example.dt.yaml: codec at 4c: ti,gpi-config:0:2: 6 is greater than the maximum of 1
/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/sound/tlv320adcx140.example.dt.yaml: codec at 4c: ti,gpi-config:0:3: 7 is greater than the maximum of 1

Please send a fix.

I believe you want '7' here.
