This adds support for the CLCD logic cell. It accepts precompiled register values for specific configuration through a board-supplied data structure. It is used by the Nomadik nhk8815, added by a later patch in this series. Signed-off-by: Alessandro Rubini <rubini@unipv.it> Acked-by: Andrea Gallo <andrea.gallo@stericsson.com>
