u-boot.git/common/usb.c, branch v2018.11 Unnamed repository; edit this file 'description' to name the repository. SPDX: Convert all of our single license tags to Linux Kernel style 2018-05-07T13:34:12+00:00 Tom Rini trini@konsulko.com 2018-05-06T21:58:06+00:00 83d290c56fab2d38cd1ab4c4cc7099559c1d5046 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 <trini@konsulko.com>

Linux Kernel has adopted SPDX tags and they place it as the very first

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.

usb: Read device descriptor after device is addressed for xHCI 2017-10-01T14:32:53+00:00 Bin Meng bmeng.cn@gmail.com 2017-09-18T13:40:43+00:00 932bb668bb2464115f2d08abbed44e58cfce9536 For xHCI it is not possible to read a device descriptor before it has been assigned an address. That's why usb_setup_descriptor() was called with 'do_read' being false. But we really need try to read the device descriptor before starting any real communication with the default control endpoint.

usb: Only get 64 bytes device descriptor for full speed devices 2017-10-01T14:32:53+00:00 Bin Meng bmeng.cn@gmail.com 2017-09-18T13:40:42+00:00 c008faa77358bb5b313696dd1d5bb8afa03a6ca2 Full speed device endpoint 0 can have 8/16/32/64 bMaxPacketSize0. Other speed devices report fixed value per USB spec. So it only makes sense if we send a get device descriptor with 64 bytes to full speed devices. While we are here, update the comment block to be within 80 cols. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

As commented in the help of "config USB_XHCI" entry, this has been a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI have been unified in favor of the former. Note: Some boards define CONFIG_USB_XHCI in their headers without CONFIG_USB, which does not meet the "depends on" in Kconfig. I added CONFIG_USB=y for those boards when converting. Otherwise, they would fail to build. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
