From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Herring Subject: [PATCH 2/2] Warn on node name unit-addresses with '0x' or leading 0s Date: Thu, 11 Feb 2016 14:46:59 -0600 Message-ID: <1455223619-16052-3-git-send-email-robh@kernel.org> References: <1455223619-16052-1-git-send-email-robh@kernel.org> Return-path: In-Reply-To: <1455223619-16052-1-git-send-email-robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org> Sender: devicetree-compiler-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: David Gibson Cc: devicetree-compiler-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Stephen Warren List-Id: devicetree@vger.kernel.org Node name unit-addresses should never begin with 0x or leading 0s regardless of whether they have a bus specific address (i.e. one with commas) or not. Add warnings to check for these cases.
