usb: gadget: ether: Handle gadget driver registration in probe and remove

2023-08-05T04:02:28Z

Move the ethernet gadget driver registration and removal from ethernet bind and unbind callbacks into driver DM probe and remove callbacks. This way, when the driver is bound, which is triggered deliberately using 'bind' command, the USB ethernet gadget driver is instantiated and bound to the matching UDC. In reverse, when the driver is unbound, which is again triggered deliberately using 'unbind' command, the USB ethernet gadget driver instance is removed. Effectively, this now behaves like running either 'ums' or 'dfu' or any other commands utilizing USB gadget functionality. This also drops use of usb_gadget_release() and moves the use of usb_gadget_initialize() into usb_ether_init() used only by legacy platforms that do not use 'bind' command properly yet. Those have no place in drivers. Signed-off-by: Marek Vasut Tested-by: Tom Rini Reviewed-by: Tom Rini

usb: gadget: ether: Move probe function above driver structure

2023-08-05T04:02:28Z

Move the driver probe function above the driver structure, so it can be placed alongside other related functions, like upcoming remove function. No functional change. Signed-off-by: Marek Vasut Tested-by: Tom Rini Tested-by: Miquel Raynal Tested-by: Miquel Raynal Reviewed-by: Tom Rini

usb: gadget: ether: Inline functions used once

These functions here are only ever called once since drop of non-DM networking code. Inline them. No functional change. Signed-off-by: Marek Vasut Tested-by: Tom Rini Tested-by: Miquel Raynal Reviewed-by: Tom Rini

usb: dwc3-generic: Restrict single ctrl node for RK3328

2023-07-31T12:33:18Z

Like Rockchip RK3568, the RK3328 also have single node to represent the glue and ctrl for USB 3.0. So, use the driver data to use single ctrl for RK3328 DWC3. Reviewed-by: Marek Vasut Signed-off-by: Jagan Teki Reviewed-by: Kever Yang

usb: dwc3-generic: Relax unsupported dr_mode check

2023-07-31T06:40:38Z

When dr_mode is peripheral or otg and U-Boot has not been built with DM_USB_GADGET support, booting such device may end up with: dwc3_glue_bind_common: subnode name: usb@fcc00000 Error binding driver 'dwc3-generic-wrapper': -6 Some drivers failed to bind initcall sequence 00000000effbca08 failed at call 0000000000a217c8 (err=-6) ### ERROR ### Please RESET the board ### Instead fail gracfully with ENODEV to allow board continue booting. dwc3_glue_bind_common: subnode name: usb@fcc00000 dwc3_glue_bind_common: unsupported dr_mode 3 Also use CONFIG_IS_ENABLED(USB_HOST) and change switch to if statements to improve readability of the code.

usb: dwc3-generic: Return early when there is no child node

The current error check for device_find_first_child is not working as expected, the documentation for device_find_first_child mention: @devp: Returns first child device, or NULL if none Return: 0 Change to return early when there is no child node to avoid any possible null pointer dereference.

usb: xhci: Fix double free on failure

2023-07-27T01:59:38Z

drivers/core/device.c will call `device_free()` after xhci_register already frees the private device data. This can cause a crash later during the boot process, observed on aarch64 RPi4b as a synchronous exception. All callers of xhci_register use priv_auto, so this won't lead to memory leaks.

usb: cdns3: gadget: Configure speed in udc_start

2023-07-21T00:05:10Z

When one of the functions does not support super speed, the composite driver forces the gadget to high speed. But the speed is never configured in the cdns3 gadget driver. So configure the speed in cdns3_gadget_udc_start just like in the kernel. Signed-off-by: Ravi Gunasekaran Reviewed-by: Marek Vasut
