2009-09-23USB: otg: fix twl4030-usb buildRandy Dunlap
subsys_initcall_sync() is only defined for built-in code, not for loadable modules, so this driver build fails when built as a module. However, the _sync() forms of the initcalls are not implemented, so this should not be used -- just use the non-sync form of it. drivers/usb/otg/twl4030-usb.c:777: warning: data definition has no type or storage class drivers/usb/otg/twl4030-usb.c:777: warning: type defaults to 'int' in declaration of 'subsys_initcall_sync' drivers/usb/otg/twl4030-usb.c:777: warning: parameter names (without types) in function declaration Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-23USB: otg: twl4030-usb.c: mark .init as subsys_initcall_syncMing Lei
This patch fixes the .probe failure of twl4030_usb driver if it is compiled into kernel. Since twl4030_usb USB transceiver .probe depends on twl4030-regulator, marking twl4030_usb_init as subsys_initcall_sync can make it called after twl4030-regulator initialization is finished, then twl4030_usb USB transceiver driver can be probed successfully.

2009-07-12Revert "USB: Add Intel Langwell USB OTG Transceiver Drive"Greg Kroah-Hartman
This reverts commit 453f77558810ffa669ed5a510a7173ec49def396. The driver should not have been accepted as the MSRT code is not in the main kernel yet, which this depends on. Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Hao Wu <hao.wu@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-06-15USB: Add Intel Langwell USB OTG Transceiver DriveHao Wu
Description: This driver is used for Intel Langwell* USB OTG controller in Intel Moorestown* platform. It tries to implement host/device role switch according to OTG spec. The actual hsot and device functions are accomplished in modified EHCI driver and Intel Langwell USB OTG client controller driver. * Langwell and Moorestown are names used in development. They are not approved official name. Note: This patch is the first version Intel Langwell USB OTG Transceiver driver. The development is not finished, and the bug fixing is on going for some hardware and software issues. The main purpose of this submission is for code view. Supported features: - Data-line Pulsing SRP - Support HNP to switch roles - PCI D0/D3 power management support Known issues: - HNP is only tested with another Moorestown platform. - PCI D0/D3 power management support is not fully tested. - VBus Pulsing SRP is not support in current version.

2009-06-15USB: nop-usb-xceiv: behave when linked as a moduleDavid Brownell
The NOP OTG transceiver driver needs to be usable from modules. Make sure its symbols are always accessible at both compile and link time, and make sure the device instance is allocated from the heap so that device lifetime rules are obeyed.

2009-06-15USB: twl4030-usb: fix minor reporting goofageDavid Brownell
Fix a reporting glitch in the twl4030 USB transceiver code. It wasn't properly distinguishing the two types of active USB link: ID grounded, vs not. In the current code that distinction doesn't much matter; in the future this bugfix should help support better USB controller communications. Provide a comment sorting out some of the cryptic bits of the manual: different sections use different names for key signals, and the register definitions don't help much without the explanations and diagrams.

2009-06-15USB: move twl4030_usb's probe function to .devinit.textUwe Kleine-König
A pointer to twl4030_usb_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

In the case where a gadget driver is removed while no transceiver was found at probe time, a bug in otg_put_transceiver() will trigger. Provide symetric calls for otg_get_transceiver() and otg_put_transceiver(), wherever a transceiver was found or not.

2009-03-24USB: otg: adding nop usb transceiverAjay Kumar Gupta
NOP transceiver is used by all the usb transceiver which are mostly autonomous and doesn't require any programming or which are built into the usb ip itself.NOP transceiver only allocates the memory for struct xceiv and calls otg_set_transceiver() so function call to otg_get_transceiver() will return a valid transceiver. NOP transceiver device should be registered by calling usb_nop_xceiv_register() from platform files.

Add driver for the high speed USB-OTG transceiver in TI's TWL4030 family of chips. Given this and various other pending patches, OMAP3 hardware like that from beagleboard.org, gumstix.com (Overo), and openpandora.org should now have basic USB host and peripheral connectivity with mainline kernels.

2009-01-07USB: otg: gpio_vbus transceiver stubPhilipp Zabel
gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

2009-01-07USB: move isp1301_omap to drivers/usb/otgDavid Brownell
This moves the isp1301-omap driver from the drivers/i2c/chips directory (which will be shrinking) into a new drivers/usb/otg directory (which will grow, with more drivers and utilities). Note that OTG infrastructure needs to be initialized before either host or peripheral side USB support, and may be needed before for pure host or pure peripheral configurations.
