usb: ci_udc: Add function to remove usb device

2020-09-01T12:47:43Z

When unregister gadget driver in ci_udc, the usb device is not removed or stop. This causes next "usb start" fails to work. Add a new interface "usb_remove_ehci_gadget" in usb-uclass to remove the usb device for DM driver. Using "usb_lowlevel_stop" for non-DM driver. Signed-off-by: Ye Li Signed-off-by: Peng Fan

usb: usb-uclass.c: Drop le16_to_cpu() as values are already swapped

2020-08-05T07:30:46Z

These values are already swapped to CPU endianess, so swapping them again is a bug. Let's remove the swap here instead. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Tested-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

usb: provide a device tree node to USB devices

2020-06-12T02:52:11Z

It is possible to specify a device tree node for an USB device. This is useful if you have a static USB setup and want to use aliases which point to these nodes, like on the Raspberry Pi. The nodes are matched against their hub port number, the compatible strings are not matched for now. Signed-off-by: Michael Walle Reviewed-by: Marek Vasut Reviewed-by: Simon Glass

usb: Keep async schedule running only across mass storage xfers

2020-04-09T19:26:59Z

Rather than keeping the asynchronous schedule running always, keep it running only across USB mass storage transfers for now, as it seems that keeping it running all the time interferes with certain control transfers during device enumeration. Note that running the async schedule all the time should not be an issue, especially on EHCI HCD, as that one implements most of the transfers using async schedule. Note that we have usb_disable_asynch(), which however is utterly broken. The usb_disable_asynch() blocks the USB core from doing async transfers by setting a global flag. The async schedule should however be disabled per USB controller. Moreover, setting a global flag does not prevent the controller from using the async schedule, which e.g. the EHCI HCD does. This patch implements additional callback to the controller, which permits it to lock the async schedule and keep it running across multiple transfers. Once the schedule is unlocked, it must also be disabled. This thus prevents the async schedule from running outside of the USB mass storage transfers.

usb: host: Print device name when scanning

2019-04-09T11:11:45Z

Drop the counter, it has no meaning other than being the order in which the interface is found; the name assigned to the USB host controller interface is a better indicator. Example of the original output: > USB0: USB EHCI 1.10 > scanning bus 0 for devices... 2 USB Device(s) found > scanning usb for storage devices... 1 Storage Device(s) found Patched output: > Bus usb@ee080100: USB EHCI 1.10 > scanning bus usb@ee080100 for devices... 2 USB Device(s) found > scanning usb for storage devices... 1 Storage Device(s) found Signed-off-by: Ismael Luceno

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
