[U-Boot] USB on mx53loco

[Fabio Estevam]

Hi Wolfgang,

Have you tested USB host functionality on a mx53loco with a Freescale
MC34708 PMIC ?

I can succesfully detect a USB pen drive on a mx53loco board with a
Dialog PMIC, but not on the FSL PMIC version.

I am going to debug this, but just wondering if you have already seen
this issue.

Thanks,

Fabio Estevam

I have a i.MX53 quick start board, which is named in U-Boot and Linux
mx53[_]loco. And yes, USB is working.

I need to check, what PMIC my board uses.

No, I tested on a board with the Dialog PMIC, and it worked flawlessy.

I have both boards here.

On a mx53loco with Dialog PMIC:

MX53LOCO U-Boot > usb start
(Re)start USB...
USB:   Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 2 USB Device(s) found
       scanning bus for storage devices... 1 Storage Device(s) found
       scanning bus for ethernet devices... 0 Ethernet Device(s) found

On a mx53loco with FSL PMIC:

MX53LOCO U-Boot > usb start
(Re)start USB...
USB:   Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... cannot reset port 1!?
1 USB Device(s) found
       scanning bus for storage devices... 0 Storage Device(s) found
       scanning bus for ethernet devices... 0 Ethernet Device(s) found

I still have not figured out why it cannot reset the USB port in this case.

I managed to get USB working in the mx53loco board with FSL PMIC.

I needed to turn on VUSB regulator output of mc34708.

Will submit the patches after my initial Dialog PMIC series get applied.

Ok, this explains why it did not work !
