usb: otg: move usb_otg_state_string to usb-common.c

2013-03-18T09:18:03+00:00

otg.c only had a single function definition which might make more sense to be placed in usb-common.c. While doing that, we also delete otg.c since it's now empty. Signed-off-by: Felipe Balbi

usb: otg: prefix otg_state_string with usb_

2013-03-18T09:18:03+00:00

all other functions under drivers/usb/ start with usb_, let's do the same thing. This patch is in preparation for moving otg_state_string to usb-common.c and deleting otg.c completely. Signed-off-by: Felipe Balbi

usb: phy: move bulk of otg/otg.c to phy/phy.c

2013-03-18T09:17:58+00:00

Most of otg/otg.c is not otg specific, but phy specific, so move it to the phy directory. Tested-by: Steffen Trumtrar Reported-by: Kishon Vijay Abraham I Signed-off-by: Sascha Hauer Signed-off-by: Marc Kleine-Budde Signed-off-by: Felipe Balbi

usb: otg: use try_module_get in all usb_get_phy functions and add missing module_put

2013-03-04T07:33:30+00:00

In patch "5d3c28b usb: otg: add device tree support to otg library" devm_usb_get_phy_by_phandle() was added. It uses try_module_get() to lock the phy driver in memory. The corresponding module_put() is missing in that patch. This patch adds try_module_get() to usb_get_phy() and usb_get_phy_dev(). Further the missing module_put() is added to usb_put_phy().

usb: otg: add device tree support to otg library

2013-01-25T08:20:14+00:00

Added an API devm_usb_get_phy_by_phandle(), to get usb phy by passing a device node phandle value. This function will return a pointer to the phy on success, -EPROBE_DEFER if there is a device_node for the phandle, but the phy has not been added, or a ERR_PTR() otherwise.

usb: otg: utils: add facilities in phy lib to support multiple PHYs of same type

2013-01-25T08:20:14+00:00

In order to add support for multipe PHY's of the same type, new API's for adding PHY and getting PHY has been added. Now the binding information for the PHY and controller should be done in platform file using usb_bind_phy API. And for getting a PHY, the device pointer of the USB controller and an index should be passed. Based on the binding information that is added in the platform file, usb_get_phy_dev will return the appropriate PHY. Already existing API's to add and get phy by type is not removed. These API's are deprecated and will be removed once all the platforms start to use the new API. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Felipe Balbi

usb: otg: add an api to bind the usb controller and phy

2013-01-25T08:20:09+00:00

In order to support platforms which has multiple PHY's (of same type) and which has multiple USB controllers, a new design is adopted wherin the binding information (between the PHY and the USB controller) should be passed to the PHY library from platform specific file (board file). So added a new API to pass the binding information. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Felipe Balbi

usb: otg: Remove the unneeded NULL check

The function usb_add_phy trusts the sanity of the caller. Also it accesses x after the NULL check. Remove the unneeded check. Signed-off-by: Shubhrajyoti D Signed-off-by: Felipe Balbi

usb: phy: fix error handling in usb_get_phy

2012-07-02T07:41:00+00:00

spin_unlock_irqrestore() was not being called in the error path of usb_get_phy. It's fixed here. Reported-by: Marc Kleine-Budde Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Felipe Balbi

usb: phy: fix return value check of usb_get_phy

2012-07-02T07:40:49+00:00

usb_get_phy will return -ENODEV if it's not able to find the phy. Hence fixed all the callers of usb_get_phy to check for this error condition instead of relying on a non-zero value as success condition. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Felipe Balbi
