Hi,
These patches add support for Tahvo USB transceiver and allow use both
host and peripheral modes on Nokia 770.
Patches work with 3.9-rc1, but the following fixes must be also applied:
ARM: OMAP1: fix USB host on 1710
http://marc.info/?l=linux-omap&m=135906630828618&w=2
usb: gadget: fix omap_udc build errors
http://marc.info/?l=linux-arm-kernel&m=136252187712475&w=2
ARM: OMAP1: fix omap_udc registration
http://marc.info/?l=linux-omap&m=136266305725974&w=2
Test cases were roughly following:
- CONFIG_USB_OTG, CONFIG_TAHVO_USB_HOST_BY_DEFAULT
- ohci-hcd, omap_udc, g_ether loaded as modules during boot
- check host mode functionality after boot with USB keyboard
- switch to peripheral mode and check functionality with ssh
- switch back to host mode
- CONFIG_USB_OTG, !CONFIG_TAHVO_USB_HOST_BY_DEFAULT
- ohci-hcd, omap_udc, g_ether loaded as modules during boot
- check peripheral mode after boot with ssh
- switch to host mode and check with USB keyboard
- switch back to peripheral mode
- !CONFIG_USB_OTG, CONFIG_USB_OMAP
- check peripheral mode after boot by logging with ssh
- !CONFIG_USB_OTG, !CONFIG_USB_OMAP
- (not currently supported by ohci-hcd)
- other
- check USB cable on/off detection (Tahvo vbus interrupt)
Please review and comment. Thanks,
A.
