Stefan Wahren 22ab6c515d dt-bindings: w1: Add DS2482/DS2484 I2C to 1-W bridges
This adds a dedicated devicetree binding for the Maxim DS2482/DS2484
I2C to 1-W bridges, which can be extended later for further features
(e.g. sleep mode control GPIO). Since one wire is a bus, child nodes
needs to be allowed here.
