From 91bd11a4a56895a9bf03c0be4ff15bd7caaaee0d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Thu, 28 Oct 2021 10:37:49 +0100 Subject: [PATCH] media: dt-bindings: adv748x: Convert bindings to json-schema MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Convert ADV748X analog video decoder documentation to json-schema. While converting the bindings extend it to enforce that all port@n nodes shall be encapsulated inside a ports node. This change does not have an effect on drivers parsing the ports@n nodes.
