Revert "usb: xhci: tegra: Fix error check"

2023-07-25T15:44:10+00:00

This reverts commit 18fc7c435be3f17ea26a21b2e2312fcb9088e01f.

The reverted commit was based on static analysis and a misunderstanding
of how PTR_ERR() and NULLs are supposed to work.  When a function
returns both pointer errors and NULL then normally the NULL means
"continue operating without a feature because it was deliberately
turned off".  The NULL should not be treated as a failure.  If a driver
cannot work when that feature is disabled then the KConfig should
enforce that the function cannot return NULL.  We should not need to
test for it.

In this code, the patch means that certain tegra_xusb_probe() will
fail if the firmware supports power-domains but CONFIG_PM is disabled.

usb: ohci-at91: Fix the unhandle interrupt when resume

2023-07-25T15:39:10+00:00

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.

According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().

usb: host: xhci-plat: Set XHCI_STATE_REMOVING before resuming XHCI HC

2023-06-23T07:55:09+00:00

There are situations during the xhci_resume() sequence, which allows for
re-initializing of the XHCI HC.  However, in case the HCD is being removed,
these operations may not be needed.  Set the removal state before issuing
the runtime PM get on the XHCI device, so that the XHCI resume routine will
know when to bypass the re-init logic.

usb: host: xhci: Do not re-initialize the XHCI HC if being removed

2023-06-23T07:55:09+00:00

During XHCI resume, if there was a host controller error detected the
routine will attempt to re-initialize the XHCI HC, so that it can return
back to an operational state.  If the XHCI host controller is being
removed, this sequence would be already handled within the XHCI halt path,
leading to a duplicate set of reg ops/calls.  In addition, since the XHCI
bus is being removed, the overhead added in restarting the HCD is
unnecessary.  Check for the XHC state before setting the reinit_xhc
parameter, which is responsible for triggering the restart.

xhci: Add ZHAOXIN xHCI host U1/U2 feature support

2023-06-13T09:34:50+00:00

Add U1/U2 feature support of xHCI for ZHAOXIN.
Since both INTEL and ZHAOXIN need to check the tier where the device is
located to determine whether to enabled U1/U2, remove the previous INTEL
U1/U2 tier policy and add common policy in xhci_check_tier_policy.
If vendor has specific U1/U2 enable policy,quirks can be add to declare.

xhci: Show ZHAOXIN xHCI root hub speed correctly

2023-06-13T09:34:50+00:00

Some ZHAOXIN xHCI controllers follow usb3.1 spec, but only support
gen1 speed 5Gbps. While in Linux kernel, if xHCI suspport usb3.1,
root hub speed will show on 10Gbps.
To fix this issue of ZHAOXIN xHCI platforms, read usb speed ID
supported by xHCI to determine root hub speed. And add a quirk
XHCI_ZHAOXIN_HOST for this issue.

xhci: Fix TRB prefetch issue of ZHAOXIN hosts

2023-06-13T09:34:50+00:00

On some ZHAOXIN hosts, xHCI will prefetch TRB for performance
improvement. However this TRB prefetch mechanism may cross page boundary,
which may access memory not allocated by xHCI driver. In order to fix
this issue, two pages was allocated for a segment and only the first
page will be used. And add a quirk XHCI_ZHAOXIN_TRB_FETCH for this issue.
