From 44d02acf54114e4d5c905b6b1a6473a7d302312d Mon Sep 17 00:00:00 2001 From: Hema HK Date: Thu, 17 Feb 2011 12:07:17 +0530 Subject: OMAP2430: hwmod data: Add USBOTG OMAP2430 hwmod data structures are populated with base address, L3 and L4 interface clocks, IRQs and sysconfig register details. As per OMAP USBOTG specification, need to configure the USBOTG to smart idle/standby or no idle/standby during data transfer and force idle/standby when not in use to support retention and off-mode. By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags, framework will take care of configuring to no idle/standby when module is enabled and force idle/standby when suspended.
