Subject: [PATCH 3.12 088/119] ARM: OMAP3: hwmod data: Add sysc information for DSI

From: Sebastian Reichel <sre@...nel.org>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit b46211d6dcfb81a8af66b8684a42d629183670d4 upstream.

Add missing sysconfig/sysstatus information
to OMAP3 hwmod. The information has been
checked against OMAP34xx and OMAP36xx TRM.

Without this change DSI block is not reset
during boot, which is required for working
Nokia N950 display.
