The device tree language as currently defined conflicts with the C pre- processor in one aspect - when a property or node name begins with a # character, a pre-processor would attempt to interpret it as a directive, fail, and most likely error out. This change allows a property/node name to be prefixed with \. This prevents a pre-processor from seeing # as the first non-whitespace character on the line, and hence prevents the conflict. \ was previously an illegal character in property/node names, so this change is backwards compatible. The \ is stripped from the name during parsing by dtc. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>
