[RFC PATCH 0/4] USB: OMAP: Tahvo USB support for 770

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
