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. Signed-off-by: Sebastian Reichel <sre@xxxxxxxxxx> --- Hi, This is an updated version of this patch [0]. Instead of the workaround implemented in [0], this patch fixes the root problem - missing hwmod data. I think it should be added to -rc.
