From 50749d2ac30dd7af94d8c9ed64276f92d9d396f5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 15 May 2017 16:07:33 +0900 Subject: [PATCH] kbuild: update DTC warning settings for bus and node/property name checks Recent commits of DTC introduced new warnings checking PCI and simple buses, unit address formatting, and stricter node and property name checking. Disable the new DTC warnings by default. As before, warnings are enabled with W=*. The strict node and property name checks are a bit subjective, so they are only enabled for W=2. (This policy reflects the commit 8654cb8d0371 of Linux.)
