From 604bd5ae91d9c6ba849e4e704b759bd29000dcb2 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Thu, 5 Dec 2019 16:34:05 +0100 Subject: [PATCH] media: dt-bindings: media: amlogic,vdec: convert to yaml Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Video Controller over to YAML schemas. This yaml bindings will then be extended to support new SoCs.
