Felipe writes: usb: patches for v4.9 merge window This time around we have 92 non-merge commits. Most of the changes are in drivers/usb/gadget (40.3%) with drivers/usb/gadget/function being the most active directory (27.2%). As for UDC drivers, only dwc3 (26.5%) and dwc2 (12.7%) have really been active. The most important changes for dwc3 are better support for scatterlist and, again, throughput improvements. While on dwc2 got some minor stability fixes related to soft reset and FIFO usage. Felipe Tonello has done some good work fixing up our f_midi gadget and Tal Shorer has implemented a nice API change for our ULPI bus. Apart from these, we have our usual set of non-critical fixes, spelling fixes, build warning fixes, etc.

usb: ulpi: make ops struct constant

2016-09-06T07:47:25Z

None of the core ulpi functions perform any changes to the operations struct, and logically as a struct that contains function pointers there's no reason it shouldn't be constant. Acked-by: Heikki Krogerus Signed-off-by: Tal Shorer Signed-off-by: Felipe Balbi

usb: ulpi: remove "dev" field from struct ulpi_ops

2016-09-06T07:47:25Z

Operations now use ulpi->dev.parent directly instead of via the ulpi_ops struct, making this field unused. Remove it. Acked-by: Heikki Krogerus Signed-off-by: Tal Shorer Signed-off-by: Felipe Balbi

usb: ulpi: rename operations {read|write}_dev to simply {read|write}

2016-09-06T07:47:24Z

With the removal of the old {read|write} operations, we can now safely rename the new api operations {read|write}_dev to use the shorter and clearer names {read|write}, respectively. Acked-by: Heikki Krogerus Signed-off-by: Tal Shorer Signed-off-by: Felipe Balbi

usb: ulpi: remove calls to old api callbacks

2016-09-06T07:47:24Z

Now that all users use the new api callbacks, remove the old api callbacks and force new interface drivers to use the new api. Acked-by: Heikki Krogerus Signed-off-by: Tal Shorer Signed-off-by: Felipe Balbi

usb: ulpi: add new api functions, {read|write}_dev()

2016-09-06T07:47:23Z

Add these two new api callbacks to struct ulpi_ops. These are different than read, write in that they pass the parent device directly instead of via the ops argument. They are intended to replace the old api functions. If the new api callbacks are missing, revert to calling the old ones as before.

usb: ulpi: move setting of ulpi->dev parent up in ulpi_register()

2016-09-06T07:47:23Z

Once ulpi operations use the parent device directly, this will be needed during the operations used in ulpi_register() itself, so set the parent field before calling any ulpi operations. Acked-by: Heikki Krogerus Signed-off-by: Tal Shorer Signed-off-by: Felipe Balbi

usb: ulpi: Automatically set driver::owner with ulpi_driver_register()

2016-08-09T14:06:49Z

Let's follow other driver registration functions and automatically set the driver's owner member to THIS_MODULE when ulpi_driver_register() is called. This allows ulpi driver writers to forget about this boiler plate detail and avoids common bugs in the process.

We want the USB fixes in here as well. 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.
