The FSA4480 Type-C switch supports switching the Audio R/L,
AGND and MIC signals to the USB-C DP/DM and SBU1/2 to support
the Audio Accessory Mode.
The FSA4480 has an integrated Audio jack detection mechanism
to automatically mux the AGND, MIX and Sense to the correct
SBU lines to support 3 pole and both 4 pole TRRS pinouts.

Add support for calling typec_set_mode() for the DEBUG, AUDIO
accessory modes.
Let's also call typec_set_mode() for USB as default and SAFE
when partner is disconnected.
The USB state is only called when ALT mode is specifically
not specified by the partner status flags in order
to leave the altmode handlers setup the proper mode to
switches, muxes and retimers.

The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP.
As the DWC3 IP supports the hibernation feature, to handle the wakeup
or hibernation interrupt, add host mode "wakeup" interrupt-names
optional property in the binding schema to capture remote-wakeup and
connect/ disconnect event in the hibernation state and increased maxItems
to 4 for the interrupts and interrupt-names property.
We have a dedicated IRQ line specifically for the hibernation feature.
When the "wakeup" IRQ line is triggered, it initiates a hibernation
interrupt, causing the system to wake up from the hibernation state.

Intel Barlow Ridge is the first USB4 v2 controller from Intel. The
controller exposes standard USB4 PCI class ID in typical configurations,
however there is a way to configure it so that it uses a special class
ID to allow using s different driver than the Windows inbox one. For
this reason add the Barlow Ridge PCI ID to the Linux driver too so that
the driver can attach regardless of the class ID.

"VBUS Valid Comparator Enable:
This signal controls the USB OTG PHY VBUS Valid comparator which
indicates whether the voltage on the USB_OTG*_VBUS pin is below
the VBUS Valid threshold. The VBUS Valid threshold is nominally
4.75V on this USB PHY. The VBUS Valid threshold can be adjusted
using the USBNC_OTGn_PHY_CFG1[OTGTUNE0] bit field. Status of the
VBUS Valid comparator, when it is enabled, is reported on the

When OTGDISABLE0 (USBNC_USB_OTGx_PHY_CFG2[10])is set to 1'b0 and
DRVVBUS0 is set to 1'b1, the Bandgap circuitry and VBUS Valid
comparator are powered, even in Suspend or Sleep mode.
DRVVBUS0 should be reset to 1'b0 when the internal VBUS Valid comparator
is not required, to reduce quiescent current in Suspend or Sleep mode.
