Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

fastboot: multiresponse support

2024-01-09T13:58:33+00:00

Currently u-boot fastboot can only send one message back to host,
so if there is a need to print more than one line messages must be
kept sending until all the required data is obtained. This behavior
can be adjusted using multiresponce ability (getting multiple lines
of response) proposed in this patch.

usb: gadget: fastboot: detach usb just before rebooting

2023-01-14T13:10:30+00:00

The patch fixes the following error when updating a BSH SMM S2 board:
3:72>Start Cmd:FB[-t 8000]: ucmd nand write ${loadaddr} nanddtb ${filesize}
3:72>Okay (0.023s)
3:72>Start Cmd:FB: reboot
3:72>Fail Bulk(R):LIBUSB_ERROR_IO(0s)

The "fastboot reboot" command detaches the USB when it still needs to be
used. So let's detach the USB just before the reset.

fastboot: remove #ifdef CONFIG when it is possible

2023-01-11T20:02:24+00:00

Much of the fastboot code predates the introduction of Kconfig and
has quite a few #ifdefs in it which is unnecessary now that we can use
IS_ENABLED() et al.

usb: gadget: fastboot: detach usb on reboot commands

2022-10-10T16:08:18+00:00

When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.

On some boards, such as Khadas VIM3L and SEI610, this is not the case.

We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot                            OKAY [  0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.

This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
  # echo b > /proc/sysrq-trigger

In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.

Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.

Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).

drivers: usb: fastboot: Fix full-speed usb descriptor

2022-09-02T11:26:58+00:00

The host will report such error message if the fastboot device work in
full-speed mode: "Duplicate descriptor for config 1 interface 0
altsetting 0, skipping"

Fastboot device ack both full and high speed interface descriptors when
work in full-speed mode, that's will cause this issue.

Fix it.
