during boot. Make sure not to output an error message in that case
because they are not useful.

USB: changes for v5.8 merge window
Rather busy cycle. We have a total 99 non-merge commits going into v5.8
merge window. The majority of the changes are in dwc3 this around (31.7%
of all changes). It's composed mostly Thinh's recent updates to get dwc3
to behave correctly with stream transfers. We have also have Roger's for
Keystone platforms and Neil's updates for the meson glue layer.
Apart from those, we have the usual set of non-critical fixes, new
device IDs, spelling fixes all over the place.

OTG port on Tegra194 supports GEN1 speeds when in device mode and GEN2
speeds when in host mode. dd port_speed_quirk that configures port to
GEN1/GEN2 speds, corresponding to the mode.

This commit adds support for XUSB device mode controller support on
Tegra194 SoC. This is very similar to the existing Tegra186 XUDC, with lpm
support added in addition.

When the XUDC device is idle (i.e. powergated), care must be taken not
to access any registers because that would lead to a crash.
Move the call to tegra_xudc_device_mode_off() into the same conditional
as the tegra_xudc_powergate() call to make sure we only force device
mode off if the XUDC is actually powered up.

USB: changes for v5.7 merge window
Lots of changes on dwc3 this time, most of them from Thinh fixing a
bunch of really old mishaps on the driver.
DWC2 got support for STM32MP15 and a couple RockChip SoCs while DWC3
learned about Amlogic A1 family.
Apart from these, we have a few spelling fixes and other minor
non-critical fixes all over the place.

platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
