From b9c320157ce3db813eaa9f0c900a33a9b7cc60a6 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 31 Oct 2020 18:48:14 +0000 Subject: [PATCH] dt-bindings:iio:samsung,sensorhub-rinato: yaml conversion Renamed to be more specific as I would be surprised if this is the only sensorhub Samsung have ever shipped. Fixed missing reg property in the example Karol's email address from original patch is bouncing, so I've put myself as maintainer until someone else steps up.
