From 0ded75428605213641897d6b8d8e9cf9fdb6eb8d Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 13 Apr 2010 10:16:34 +0900 Subject: sh: intc: Provide sysdev name for intc controllers. Presently the sysdevs are simply numbered based on the list position, without having any direct way of figuring out which controller these are actually mapping to. This provides a name attr for mapping out the chip name.
