From 54a7fbcc17bc2881807ea8e65fa0857ec8a3a863 Mon Sep 17 00:00:00 2001 From: Franklin S Cooper Jr Date: Tue, 16 Jan 2018 17:07:11 +0530 Subject: [PATCH] dt-bindings: can: can-transceiver: Document new binding Add documentation to describe usage of the new can-transceiver binding. This new binding is applicable for any CAN device therefore it exists as its own document.
