Looking up init data for regulators found on chips is a common operation that can be handled in a generic way. The new helper function introduced by this patch looks up the children of a given node by names specified in a match table and fills that match table with information parsed from the DT. This is based on work by Rhyland Klein <rklein@nvidia.com>. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
