I'd like to add something on the topic of non-Linux projects. In this case it's diverging DT bindings from U-boot: https://patchwork.ozlabs.org/patch/823158/ U-boot already has a set of devicetree binding additions: https://github.com/u-boot/u-boot/tree/master/doc/device-tree-bindings The patch in question wants to ab(use) the regulator-name property for driver instance binding. In my opinion this is not going to fly, as boards are free to define the names. This either sees no use other than as a dirty workaround for dts files that aren't following the PMIC regulator bindings (regulator node names should follow well defined, identifying names), or results in divergence of the DT files. So far I've been unable to dissuade the author. Unfortunately I won't be attending the workshop, as I had planned on some sightseeing and the workshop is already full right now. Hope this gets discussed in some manner.
