The new version has a significant change, which drops the EMC table bindings and replaces by memory region node of EMC table. And most of the comments in V1 have been addressed. Thanks. v4: * make sure the behavior is compatible with the case if the kernel uses the older DTB which doesn't have EMC node. * remove the EMC clock statistic data in EMC debug fs.
