From b0a70cc80e754f5ad7d83c96e005fa1d5cb83514 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Wed, 4 Jul 2012 06:55:29 -0600 Subject: ARM: OMAP4: hwmod data: temporarily comment out data for the usb_host_fs and aess IP blocks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special programming for them to enter idle. Without this programming, they will prevent the rest of the chip from entering full chip idle. To implement the idle programming cleanly, this will take some coordination between maintainers. This is likely to take some time, so it is probably best to leave this for 3.6 or 3.7. So, in the meantime, prevent these IP blocks from being registered. Later, once the appropriate support is available, this patch can be reverted. This second version comments out the IP block data since Benoît didn't like removing it.
