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

2023-08-03T08:26:05+00:00

commit 288b4fa1798e3637a9304c6e90a93d900e02369c upstream.

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: cdns3: fix incorrect calculation of ep_buf_size when more than one config

2023-08-03T08:26:04+00:00

commit 2627335a1329a0d39d8d277994678571c4f21800 upstream.

Previously, the cdns3_gadget_check_config() function in the cdns3 driver
mistakenly calculated the ep_buf_size by considering only one
configuration's endpoint information because "claimed" will be clear after
call usb_gadget_check_config().

The fix involves checking the private flags EP_CLAIMED instead of relying
on the "claimed" flag.

USB: quirks: add quirk for Focusrite Scarlett

2023-08-03T08:26:04+00:00

commit 9dc162e22387080e2d06de708b89920c0e158c9a upstream.

The Focusrite Scarlett audio device does not behave correctly during
resumes. Below is what happens during every resume (captured with
Beagle 5000):



//



The Scarlett disconnects and is enumerated again.

However from time to time it drops completely off the USB bus during
resume. Below is captured occurrence of such an event:



//
//




To fix the condition a user has to unplug and plug the device again.

With USB_QUIRK_RESET_RESUME applied ("usbcore.quirks=1235:8211:b")
for the Scarlett audio device the issue still reproduces.

Applying USB_QUIRK_DISCONNECT_SUSPEND ("usbcore.quirks=1235:8211:m")
fixed the issue and the Scarlett audio device didn't drop off the USB
bus for ~5000 suspend/resume cycles where originally issue reproduced in
~100 or less suspend/resume cycles.

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

2023-08-03T08:26:04+00:00

commit c55afcbeaa7a6f4fffdbc999a9bf3f0b29a5186f upstream.

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().

commit 7f2327666a9080e428166964e37548b0168cd5e9 upstream.

usb: dwc3: don't reset device side if dwc3 was configured as host-only

2023-08-03T08:26:04+00:00

commit e835c0a4e23c38531dcee5ef77e8d1cf462658c7 upstream.

Commit c4a5153e87fd ("usb: dwc3: core: Power-off core/PHYs on
system_suspend in host mode") replaces check for HOST only dr_mode with
current_dr_role. But during booting, the current_dr_role isn't
initialized, thus the device side reset is always issued even if dwc3
was configured as host-only. What's more, on some platforms with host
only dwc3, aways issuing device side reset by accessing device register
block can cause kernel panic.

usb: dwc3: pci: skip BYT GPIO lookup table for hardwired phy

2023-08-03T08:26:04+00:00

commit b32b8f2b9542d8039f5468303a6ca78c1b5611a5 upstream.

Hardware based on the Bay Trail / BYT SoCs require an external ULPI phy for
USB device-mode. The phy chip usually has its 'reset' and 'chip select'
lines connected to GPIOs described by ACPI fwnodes in the DSDT table.

Because of hardware with missing ACPI resources for the 'reset' and 'chip
select' GPIOs commit 5741022cbdf3 ("usb: dwc3: pci: Add GPIO lookup table
on platforms without ACPI GPIO resources") introduced a fallback
gpiod_lookup_table with hard-coded mappings for Bay Trail devices.

However there are existing Bay Trail based devices, like the National
Instruments cRIO-903x series, where the phy chip has its 'reset' and
'chip-select' lines always asserted in hardware via resistor pull-ups. On
this hardware the phy chip is always enabled and the ACPI dsdt table is
missing information not only for the 'chip-select' and 'reset' lines but
also for the BYT GPIO controller itself "INT33FC".

With the introduction of the gpiod_lookup_table initializing the USB
device-mode on these hardware now errors out. The error comes from the
gpiod_get_optional() calls in dwc3_pci_quirks() which will now return an
-ENOENT error due to the missing ACPI entry for the INT33FC gpio controller
used in the aforementioned table.

This hardware used to work before because gpiod_get_optional() will return
NULL instead of -ENOENT if no GPIO has been assigned to the requested
function. The dwc3_pci_quirks() code for setting the 'cs' and 'reset' GPIOs
was then skipped (due to the NULL return). This is the correct behavior in
cases where the phy chip is hardwired and there are no GPIOs to control.

Since the gpiod_lookup_table relies on the presence of INT33FC fwnode
in ACPI tables only add the table if we know the entry for the INT33FC
gpio controller is present. This allows Bay Trail based devices with
hardwired dwc3 ULPI phys to continue working.

Revert "usb: dwc3: core: Enable AutoRetry feature in the controller"

2023-08-03T08:26:03+00:00

commit 734ae15ab95a18d3d425fc9cb38b7a627d786f08 upstream.

This reverts commit b138e23d3dff90c0494925b4c1874227b81bddf7.

AutoRetry has been found to sometimes cause controller freezes when
communicating with buggy USB devices.

This controller feature allows the controller in host mode to send
non-terminating/burst retry ACKs instead of terminating retry ACKs
to devices when a transaction error (CRC error or overflow) occurs.

Unfortunately, if the USB device continues to respond with a CRC error,
the controller will not complete endpoint-related commands while it
keeps trying to auto-retry. [3] The xHCI driver will notice this once
it tries to abort the transfer using a Stop Endpoint command and
does not receive a completion in time. [1]
This situation is reported to dmesg:

[sda] tag#29 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD IN
[sda] tag#29 CDB: opcode=0x28 28 00 00 69 42 80 00 00 48 00
xhci-hcd: xHCI host not responding to stop endpoint command
xhci-hcd: xHCI host controller not responding, assume dead
xhci-hcd: HC died; cleaning up

Some users observed this problem on an Odroid HC2 with the JMS578
USB3-to-SATA bridge. The issue can be triggered by starting
a read-heavy workload on an attached SSD. After a while, the host
controller would die and the SSD would disappear from the system. [1]

Further analysis by Synopsys determined that controller revisions
other than the one in Odroid HC2 are also affected by this.
The recommended solution was to disable AutoRetry altogether.
This change does not have a noticeable performance impact. [2]

Revert the enablement commit. This will keep the AutoRetry bit in
the default state configured during SoC design [2].
