usb: roles: Allow the role switches to be named

2020-03-04T10:12:50Z

The switch devices have been named by using the name of the parent device as base for now, but if for example the parent device controls multiple muxes, that will not work. Adding an optional member "name" to the switch descriptor that can be used for naming the switch during registration.

usb: roles: Provide the switch drivers handle to the switch in the API

2020-03-04T10:12:50Z

The USB role callback functions had a parameter pointing to the parent device (struct device) of the switch. The assumption was that the switch parent is always the controller. Firstly, that may not be true in every case, and secondly, it prevents us from supporting devices that supply multiple muxes. Changing the first parameter of usb_role_switch_set_t and usb_role_switch_get_t from struct device to struct usb_role_switch.

usb: roles: Leave the private driver data pointer to the drivers

2020-03-04T10:12:49Z

Adding usb_role_switch_get/set_drvdata() functions that the switch drivers can use for setting and getting private data pointer that is associated with the switch.

usb: roles: fix a potential use after free

2019-12-10T10:41:18Z

Free the sw structure only after we are done using it. This patch just moves the put_device() down a bit to avoid the use after free.

usb: roles: get usb-role-switch from parent

2019-09-03T16:00:43Z

when the USB host controller is the parent of the connector, usually type-B, sometimes don't need the graph, so we should check whether it's parent registers usb-role-switch or not firstly, and get it if exists.

The fwnode_usb_role_switch_get() function is exactly the same as usb_role_switch_get(), except that it takes struct fwnode_handle as parameter instead of struct device.

drivers: Introduce device lookup variants by fwnode

Add a helper to match the firmware node handle of a device and provide wrappers for {bus/class/driver}_find_device() APIs to avoid proliferation of duplicate custom match functions. Cc: "David S.
