Here is the big set of USB and Thunderbolt driver changes for 5.17-rc1.
Nothing major in here, just lots of little updates and cleanups. These
include:
- some USB header fixes picked from Ingo's header-splitup work
- more USB4/Thunderbolt hardware support added
- USB gadget driver updates and additions
- USB typec additions (includes some acpi changes, which were
acked by the ACPI maintainer)
- core USB fixes as found by syzbot that were too late for
5.16-final
- USB dwc3 driver updates
- USB dwc2 driver updates
- platform_get_irq() conversions of some USB drivers
- other minor USB driver updates and additions
All of these have been in linux-next for a while with no reported
issues.

The ChipIdea glue drivers just copy the glue resources to the "ci_hdrc"
child device. Instead, set the child device's DT node pointer to the
parent device's node so that platform_get_irq() can find the IRQ
resources in the DT. This removes the need for statically populating the
IRQ resources from the DT which has been deprecated for some time.

The Tegra USB controller belongs to the core power domain and we're going
to enable GENPD support for the core domain. Now USB controller must be
resumed using runtime PM API in order to initialize the USB power state.
We already support runtime PM for the CI device, but CI's PM is separated
from the RPM managed by tegra-usb driver. Add runtime PM and OPP support
to the driver.

If the first call to devm_usb_get_phy_by_phandle(dev, "fsl,usbphy", 0)
fails with something other than -ENODEV then it leads to an error
pointer dereference. For those errors we should just jump directly to

Chipidea core was calling the interrupt handler from non-IRQ context
with interrupts enabled, something which can lead to a deadlock if
there's an actual interrupt trying to take a lock that's already held
(e.g. the controller lock in udc_irq()).
Add a wrapper that can be used to fake interrupts instead of calling the
handler directly.

Root-cause:
There is an issue like endpoint is not recognized as primed, when bus
have more pressure and the add dTD tripwire semaphore (ATDTW bit in
USBCMD register) that can cause the controller to ignore a dTD that is
added to a primed endpoint.
This issue observed with the Windows10 host machine.
Workaround:
The software must implement a periodic cycle, and check for each dTD,
if the endpoint is primed. It can do this by reading the corresponding
bits in the ENDPTPRIME and ENDPTSTAT registers. If these bits are read
at 0, the software needs to re-prime the endpoint by writing 1 to the
corresponding bit in the ENDPTPRIME register.
Added conditional revision check of 2.20[CI_REVISION_22].

When passing 'phys' in the devicetree to describe the USB PHY phandle
(which is the recommended way according to
Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt) the
following NULL pointer dereference is observed on i.MX7 and i.MX8MM:

[ 1.573973] lr : imx7d_charger_detection+0x22c/0x510
This happens because the charger functions check for the phy presence
inside the imx_usbmisc_data structure (data->usb_phy), but the chipidea
core populates the usb_phy passed via 'phys' inside 'struct ci_hdrc'
(ci->usb_phy) instead.
This causes the NULL pointer dereference inside imx7d_charger_detection().
Fix it by also searching for 'phys' in case 'fsl,usbphy' is not found.
Tested on a imx7s-warp board.

i.MX8MM cannot detect certain CDP USB HUBs. usbmisc_imx.c driver is not
following CDP timing requirements defined by USB BC 1.2 specification
and section 3.2.4 Detection Timing CDP.
During Primary Detection the i.MX device should turn on VDP_SRC and
IDM_SINK for a minimum of 40ms (TVDPSRC_ON). After a time of TVDPSRC_ON,
the i.MX is allowed to check the status of the D- line. Current
implementation is waiting between 1ms and 2ms, and certain BC 1.2
complaint USB HUBs cannot be detected. Increase delay to 40ms allowing
enough time for primary detection.
During secondary detection the i.MX is required to disable VDP_SRC and
IDM_SNK, and enable VDM_SRC and IDP_SINK for at least 40ms (TVDMSRC_ON).
Current implementation is not disabling VDP_SRC and IDM_SNK, introduce
disable sequence in imx7d_charger_secondary_detection() function.
VDM_SRC and IDP_SINK should be enabled for at least 40ms (TVDMSRC_ON).

The OF core adds an alias based on the OF device ID table, which is enough
to have the driver autoloaded. The legacy MODULE_ALIAS macro was relevant
to a pre-OF board files which manually created platform devices, this is
irrelevant to the modern ARM kernels since devices are created by the OF
core. Remove the unnecessary macro in order to keep the driver's code
cleaner.

If runtime dr_mode is not dual-role, it doesn't need to enable ID

If runtime dr_mode is host, it doesn't need to enable VBUS
wakeup interrupt.
With these changes, the user will not get the unexpected wakeup

Micro-AB port, the controller should not be waken up by only

as well as not the nicest thing to do in a uapi file.
So fix that up and add the USB_ prefix on to them, and fix up all
in-kernel usages. This included deleting the duplicate copy in the
net2272.h file.
