From e70357e35c522776d9f56f6800af4ed7a5bdbaaf Mon Sep 17 00:00:00 2001 From: Hema HK Date: Fri, 10 Dec 2010 18:09:52 +0530 Subject: mfd: TWL6030: OMAP4: Registering the TWL6030-usb device Registering the twl6030-usb transceiver device as a child to twl6030 core. Removed the NOP transceiver init call from board file. Populated twl4030_usb_data platform data structure with the function pointers for OMAP4430 internal PHY operation to be used by twl630-usb driver.
