usb: usb_submit_int_msg -> usb_int_msg

2019-09-11T08:11:29+00:00

This aligns naming with usb_bulk_msg and usb_control_msg.

usb: s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/

2018-11-26T20:19:03+00:00

This allows to disable the USB driver model in SPL because it checks
the CONFIG_SPL_DM_USB variable for SPL builds. Nothing changes for
regular non-SPL builds.

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

2018-05-07T13:34:12+00:00

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.

usb: Read device descriptor after device is addressed for xHCI

2017-10-01T14:32:53+00:00

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

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.

usb: Handle audio extension endpoint descriptor in usb_parse_config()

2017-10-01T14:32:53+00:00

Normal endpoint descriptor size is 7, but for audio extension it is
9. Handle that correctly when parsing endpoint descriptor.

powerpc: remove 4xx support

2017-07-03T21:35:28+00:00

There was for long time no activity in the 4xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 4xx,
so remove it.

usb: move CONFIG_USB_XHCI to Kconfig with renaming

2016-06-03T22:43:53+00:00

Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it
into CONFIG_USB_XHCI_HCD.

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.
