Hi,
These patches add support for Tahvo USB transceiver and allow using both
host and peripheral modes on Nokia 770.
Patches are currently based on top of Felipe's "next" branch
(git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git,
9b192de60b5a584ee4ed967fb6758773c75e4643). To make them work on 770,
some additional OMAP1 fixes are also needed which are already present
in 3.9-rc6 or queued for 3.10.
Test cases were roughly following:
- 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_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
- other
- check USB cable on/off detection (Tahvo vbus interrupt)
Changes since the first RFC
(http://marc.info/?l=linux-omap&m=136266725827698&w=2):
- retu-mfd
- use i2c address to detect retu vs. tahvo
- phy-omap-otg
- don't mess with isp1301_omap.c
- move to drivers/usb/phy, rename omap-otg -> phy-omap-otg
- phy-tahvo
- drop illegal includes
- move to drivers/usb/phy, rename tahvo-usb -> phy-tahvo
- serialize vbus interrupt handling
- delete dummy/unimplemented functions
- drop peripheral/host only config
- don't use OTG interrupt, not needed
- don't write to OTG_SYSCON_1/2, this is handled by board code
- move OTG CTRL handling to omap-otg
Please review and comment. Thanks,
A.
