2013-12-19usb: phy: omap: Add omap-control Support for AM437xGeorge Cherian1-0/+19

2013-12-19usb: phy: am335x-control: include appropriate header file in phy-am335x-control.cRashika Kheria1-5/+1
Include header file drivers/usb/phy/am35x-phy-control.h in phy/phy-am335x-control.c because function am335x_get_phy_control() has its prototype declaration in drivers/usb/phy/am35x-phy-control.h. Also, remove definition of structure phy_control because it is already defined in the included header. This eliminates the following warning in phy/phy-am335x-control.c: drivers/usb/phy/phy-am335x-control.c:114:21: warning: no previous prototype for ‘am335x_get_phy_control’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Felipe Balbi <balbi@ti.com>

The reset_gpio member of the usb_phy_gen_xceiv_platform_data structure needs the have negative value or phy-generic's probe will fail unless DT is used. 0 is a valid gpio number.

2013-12-19usb: phy: am335x: Enable USB remote wakeup using PHY wakeupGeorge Cherian1-11/+35
USB remote wakeup using PHY wakeup is supported only in standby mode. Enabling the PHY_WKUP will break DS0 mode of system suspend. If the same is enabled while entering DS0, AM33xx never stays in DS0, it returns immediately from DS0. By default make the PHY wakeup disabled, using sysfs entry enable the same manually to get the remote wakeup working from standby. echo enabled > /sys/bus/platform/device/<usb phy id>/power/wakeup This will enable the PHY wakeup while going to standby. PHY wakeup feature is required to wakeup the system from standby state. Since AM33xx has a bug in which PHY wakeup should not be enabled while entering DS0, disable the same by default. A user wishing to use USB wakeup from standby mode need to enable the same using the sysfs entries. Also remove am335x_phy_runtime_(suspend/resume) this driver doesnot really enable/disable the clocks to the PHY. Add am335x_phy_(suspend/resume) and use the same for enabling the PHY_WKUP.

This is because we don't tackle endpoint halt error condition in any of the tests. To avoid that situation, make sure to clear the halt condition before exiting test_halt().

2013-12-17usbtest: Fix BOS control test for USB 2.01 devices.Sarah Sharp1-1/+1
Commit c952a8ba7136505cd1ca01735cc748ddc08c7d2f "usb: usbtest: add a test case to support bos for queue control" will cause USB 2.01 and USB 2.10 devices with a BOS descriptor to fail case 15 of the control test. The Link PM errata (released in 2007, updated in 2011) says: "The value of the bcdUSB field in the standard USB 2.0 Device Descriptor is used to indicate that the device supports the request to read the BOS Descriptor (i.e. GetDescriptor(BOS)). Devices that support the BOS descriptor must have a bcdUSB value of 0201H or larger." The current code says that non-SuperSpeed devices *must* return -EPIPE, as this comment shows: /* sign of this variable means: * -: tested code must return this (negative) error code * +: tested code may return this (negative too) error code */ int expected = 0; This means the test will fail with USB 2.01 and USB 2.10 devices that provide a BOS descriptor. Change it to only require a stall response if the USB device bcdUSB is less than 2.01. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Acked-by: Huang Rui <ray.huang@amd.com>

2013-12-17usb: gadget: nokia: fix error recovery path for optional functionsAndrzej Pietrasiewicz1-3/+3
In the nokia gadget some USB functions (obex 1 and 2, phonet) are optional. If at the start of nokia_bind_config e.g. fi_phonet is an error pointer, which can happen because we don't fail the bind process if usb_get_function_instance() fails for fi_phonet, then f_phonet is NULL, and phonet_stat = usb_add_function(c, f_phonet); is never called and phonet_stat remains 0. If, in these circumstances, we hit the err_conf label then !phonet_stat evaluates to true and we try usb_remove_function() with its second parameter being f_phonet which is NULL and it causes NULL pointer dereference. This patch changes the initial values of (obex1|obex2|phonet)_stat to a nonzero value so that if the err_conf label is hit while the respective functions have not been acquired the usb_remove_function() is not called for those functions.

2013-12-17usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga29-61/+73
This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.
