OK, I applied:
$ git log --oneline master..
93460ef OMAP4/5: Add USB EHCI support
d18c49c OMAP5: Enable USB Ethernet support with LAN9730
15a4481 OMAP5: Enable access to auxclk registers
f307fc2 OMAP5: Power: Add more functionality to Palmas driver
efdf00c OMAP5: uEVM: Enable USB EHCI functionality (preliminary, not tested)
And added:
+#define CONFIG_USB_ULPI
+#define CONFIG_USB_ULPI_VIEWPORT_OMAP
to include/configs/omap5_uevm.h
And usb start/usb rescan don't see any devices.
OMAP5432 uEVM # usb start
(Re)start USB...
USB0: USB EHCI 1.00
scanning bus 0 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) found
Cable was plugged into the eth and a storage device was also plugged in.
I suspect that we need to set CONFIG_OMAP_EHCI_PHY1_RESET_GPIO /
CONFIG_OMAP_EHCI_PHY2_RESET_GPIO. I'm looking around for the schematic
so I can try and find that out.
