From 02bfc030e4417003b7a94393102c92e39b2dfa65 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 3 Sep 2009 20:14:05 +0300 Subject: OMAP: omap_hwmod: call omap_hwmod init at boot; create interconnects Connect the omap_hwmod code to the kernel boot. Create some basic interconnect and device structures for OMAP2/3 chips.
