[PATCH 0/7 V2] usb: otg: TWL6030: OMAP4430: musb & transceiver driver support for OMAP4

[Hema HK]

This patch series has the support for TWL6030-usb
transceiver driver and changes in the musb driver to make it functional
with OMAP4430.

OMAP4 musb support UTMI and ULPI transceiver interfaces.

In UTMI mode, the transceiver functionality is split between
the TWL6030 PMIC chip and OMAP4 embedded PHY.
The TWL6030 transceiver driver code is under otg folder and
internal UTMI PHY specific code changes are defined under
mach-omap2 directory and functions are passed through platform_data
structure.

This patch series is based on V2.6.37-rc4 + [1]+[2]

[2] Felipe's musb-reorg patch series.

Tested musb device and host mode functionality with OMAP4430SDP
and OMAP3630 ZOOM3.

Limitation: In OTG and Host only mode, when the device is connected
during boot will not be detected.
Need connect the device only after the boot. Or disconnect and connect
it back if it connected during boot.
Fix for this will be submitted later.

Version 2 changes:

-Removed the dependency on the atomic notifier patches from Arnaud.
-Fixed review comments from Felipe and Sergei.
-Modified the vbus_set function to set timeout when musb is not configured
as A device.
