From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Herring Subject: [PATCH] checkpatch: add DT compatible string documentation check Date: Tue, 26 Nov 2013 10:01:15 -0600 Message-ID: <1385481675-26675-1-git-send-email-robherring2@gmail.com> Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: Rob Herring , Grant Likely , Andy Whitcroft , Joe Perches List-Id: devicetree@vger.kernel.org From: Rob Herring This adds a simple check that any compatible strings in DeviceTree dts files are present in Documentation/devicetree/bindings. This should be a temporary check until we have more sophisticated binding schema checking.
