USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: of: add functions to bind a companion controller

2017-03-17T04:24:48Z

EHCI controllers will have a companion controller. However, on platform bus, there was difficult to bind them in previous code. So, this patch adds helper functions to bind them using a "companion" property. Signed-off-by: Yoshihiro Shimoda Acked-by: Rob Herring Signed-off-by: Greg Kroah-Hartman

USB: Fix of_usb_get_dr_mode_by_phy with a shared phy block

2016-06-21T07:52:39Z

Some SoCs have a single phy-hw-block with multiple phys, this is modelled by a single phy dts node, so we end up with multiple controller nodes with a phys property pointing to the phy-node of the otg-phy. Only one of these controllers typically is an otg controller, yet we were checking the first controller who uses a phy from the block and then end up looking for a dr_mode property in e.g. the ehci controller. This commit fixes this by adding an arg0 parameter to of_usb_get_dr_mode_by_phy and make of_usb_get_dr_mode_by_phy check that this matches the phandle args[0] value when looking for the otg controller.

USB: core: let USB device know device node

2016-03-05T20:05:01Z

Although most of USB devices are hot-plug's, there are still some devices are hard wired on the board, eg, for HSIC and SSIC interface USB devices. If these kinds of USB devices are multiple functions, and they can supply other interfaces like i2c, gpios for other devices, we may need to describe these at device tree. In this commit, it uses "reg" in dts as physical port number to match the phyiscal port number decided by USB core, if they are the same, then the device node is for the device we are creating for USB core.

usb: of: fix build breakage on !OF

2015-12-17T15:55:41Z

If OF is disabled, we will try to define a stub for of_usb_get_dr_mode_by_phy(), however that missed a static inline annotation which made us redefine the stub over and over again. Fix that. Fixes: 98bfb3946695 ("usb: of: add an api to get dr_mode by the phy node") Signed-off-by: Felipe Balbi

usb: of: add an api to get dr_mode by the phy node

2015-12-15T15:12:41Z

Some USB phy drivers have different handling for the controller in each dr_mode. But the phy driver does not have visibility to the dr_mode of the controller. This adds an api to return the dr_mode of the controller which associates the given phy node. Signed-off-by: Bin Liu Signed-off-by: Felipe Balbi
