Matthieu CASTET 65fd42724a USB: ehci tdi : let's tdi_reset set host mode
tdi_reset is already taking care of setting host mode for tdi devices.
Don't duplicate code in platform driver.

Make ehci_halt a nop if the controller is not in host mode (otherwise it 
will fail), and let's ehci_reset do the tdi_reset.
We need to move hcd->has_tt flags before ehci_halt, in order ehci_halt 
knows we are a tdi device.


Before the setup routine was doing :
- put controller in host mode
- ehci_halt
- ehci_init
- hcd->has_tt = 1;
- ehci_reset

Now we do :
- hcd->has_tt = 1;
- ehci_halt
- ehci_init
- ehci_reset

PS : now we handle correctly the device -> host transition.

Randy Vinson 80cb9aee01 [PATCH] USB: EHCI for Freescale 83xx
Adding a Host Mode USB driver for the Freescale 83xx.

This driver supports both the Dual-Role (DR) controller and the
Multi-Port-Host (MPH) controller present in the Freescale MPC8349. It has
been tested with the MPC8349CDS reference system. This driver depends on
platform support code for setting up the pins on the device package in a
manner appropriate for the board in use. Note that this patch requires
selecting the EHCI controller option under the USB Host menu.
