[PATCH v9 02/20] mfd: omap-usb-host: Consolidate OMAP USB-HS platform data

From: Roger Quadros <hidden>

Hi Greg,

Let's have a single platform data structure for the OMAP's High-Speed
USB host subsystem instead of having 3 separate ones i.e. one for
board data, one for USB Host (UHH) module and one for USB-TLL module.

This makes the code much simpler and avoids creating multiple copies of
platform data.

For the ehci-omap.c part:

Could you please ACK the drivers/usb/host/ehci-omap.c part
so that this can go through the MFD tree. Thanks.

The reason it needs to go through MFD is that it depends on
a platform header change which Samuel and Tony have agreed to share.

cheers,
