ARM: dts: imx53-qsb: Allow usb peripheral mode to work
Trying to use the usb otg port on mx53qsb results in the following error: $ modprobe g_ether using random self ethernet address using random host ethernet address usb0: HOST MAC 52:0f:8a:1e:aa:09 usb0: MAC de:f3:70:d8:6c:62 using random self ethernet address using random host ethernet address g_ether gadget: Ethernet Gadget, version: Memorial Day 2008 g_ether gadget: g_ether ready (Connect the USB cable) $ ci_hdrc ci_hdrc.0: remove, state 4 usb usb1: USB disconnect, device number 1 ci_hdrc ci_hdrc.0: USB bus 1 deregistered ci_hdrc ci_hdrc.0: timeout waiting for 00000800 in 11 USB otg port goes to connector J3 (mini USB) and also to the USB combo (J2). As mx53qsb does not provide a USB ID pin, pass the dr_mode as 'peripheral' so that we can have usb device working. Tested via g_ether.
