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.

cyclic: Use schedule() instead of WATCHDOG_RESET()

Globally replace all occurances of WATCHDOG_RESET() with schedule(),
which handles the HW_WATCHDOG functionality and the cyclic
infrastructure.

usb: ehci-hcd: Add IAA handshake for removing async QH

2021-04-22T19:09:57+00:00

According to EHCI spec, software needs to do handshake with HC for
safely removing QH from async list. This handshake is implemented by
setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD
register and poll the IAA (Interrupt on Async Advance bit) in the
USB_USBSTS to ensure the HC has released all on-chip state that may
potentially reference one of the data structures just removed.

Current codes only check active status of the last QTD, but this can't
ensure the QH is released from HC. We can meet unrecoverable
"EHCI timed out on TD" errors when running UEFI SCT tests on USB disk.
The USB_ASYNCLISTADDR register is changed to a invalid address when the
issue happens. It is fixed after adding the IAA handshake.

Steps to reproduce the issue:
1. Build the UEFI SCT from https://github.com/tianocore/edk2-test
2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2
3. Copy SCT files and Shell.efi to USB disk FAT partition
4. Load the Shell.efi from USB FAT, and run bootefi to execute it
5. After booting into Shell, enter the SCT directory and run "sct -a"
   to execute all tests.
6. Tests run about 1 hour and stop with many EHCI timeout errors like
   EHCI timed out on TD - token=0x801f8c80
