Yes, for Geotab. We are working on bringing up a new BSP and we have tps25750
which doesn't have a driver in Linux yet. We developed the driver but I thought
I needed to get the dt-bindings accepted first before sending the patch for
the driver.

Sorry, this is my first time contributing to Linux. Maybe this question
was asked before but for some reason I couldn't find it.

What is usually the process? Should I upload the driver too?
