dtc gained 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 there are 1000s. As before, warnings are enabled with W=1 or W=2. The strict node and property name checks are a bit subjective, so they are only enabled for W=2. Signed-off-by: Rob Herring <robh@kernel.org>

# Simple script to update the version of DTC carried by the Linux kernel
|
|
#
|
|
# This script assumes that the dtc and the linux git trees are in the
|
|
# same directory. After building dtc in the dtc directory, it copies the
|
|
# source files and generated source files into the scripts/dtc directory
|
|
# in the kernel and creates a git commit updating them to the new
|
|
# version.
|
|
#
|
|
# Usage: from the top level Linux source tree, run:
|
|
# $ ./scripts/dtc/update-dtc-source.sh
|
|
#
|
|
# The script will change into the dtc tree, build and test dtc, copy the
|
|
# relevant files into the kernel tree and create a git commit. The commit
|
|
# message will need to be modified to reflect the version of DTC being
|
|
# imported
|
|
#
|
|
# TODO:
|
|
# This script is pretty basic, but it is seldom used so a few manual tasks
|
|
# aren't a big deal. If anyone is interested in making it more robust, the
|
|
# the following would be nice:
|
|
# * Actually fail to complete if any testcase fails.
|
|
# - The dtc "make check" target needs to return a failure
|
|
# * Extract the version number from the dtc repo for the commit message
|
|
# * Build dtc in the kernel tree
|
|
# * run 'make check" on dtc built from the kernel tree
