The TLL (Transceiver Less Link) is an separate IP block, independent of
the host controller. Basically this TLL operates like USB PHY which allows
the user to connect two USB transceiver interfaces together directly
without the use of differential transceivers in omap3 and later chips.
The TLL configuration is removed from the UHH driver and implemented as
a seperate platform driver. Now, the UHH driver configures the TLL
through API's exported by the TLL platform driver.

The platform device name "usbhs_tll" is added for the functional,
interface and channel clocks of the TLL module.

The platform driver for the TLL component of the OMAP USB host controller
is implemented. Depending on the TLL hardware revision , the TLL channels
are configured. The USB HS core driver uses this driver through exported
APIs from the TLL platform driver.
usb_tll_enable and usb_tll_disble are the exported APIs of the USB TLL
platform driver.

The TLL specific code such as channels clocks enable/disable,
initialization functions are removed from the USBHS core
driver. The hwmod of the usb tll is retrieved and omap device
build is performed to created the platform device for the
usb tll component.

All 5 patches applied now. I had to manually apply patches #1 and #5. Could
you please check that it's looking good to you ?

Please re-send this one separately once patches 2-4 of this series have

Hi Samuel,
I've queued patch 1 of this series for 3.7, which should go upstream via
the OMAP -> arm-soc path. Also asked Keshava to re-send patch 5 to me
once patches 2-4 have been merged.
It's up to you how to handle patches 2-4. The series is a good step
forward for us in terms of cleanup. But what is probably worthwhile at
some point is for that USB TLL "phy" code (added in patch 2) to be moved
into some place like drivers/usb/phy, since it's not MFD-related.

That would be ideal, yes. I kept patches 2-4 as they're alreeady going in the
right direction (I dropped patches 1 and 5).
Thanks for the heads up.
Cheers,
Samuel.
