653e11eae2 dt-bindings: usb: Correct indentation and style in DTS example
DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

No functional changes here, but saves some comments during reviews of
new patches built on existing code.

fd2a052ccd dt-bindings: usb: add common Type-C USB Switch schema
Several bindings implement parts of Type-C USB orientation and mode
switching, and retiming.  Keep definition of such properties in one
place, new usb-switch schema, to avoid duplicate defines.

c3097719e4 dt-bindings: usb: fsa4480: Add compatible for OCP96011
The Orient-Chip OCP96011 is generally compatible with the FSA4480, add a
compatible for it with the fallback on fsa4480.

However the AUX/SBU connections are expected to be swapped compared to
FSA4480, so document this in the data-lanes description.

fad89aa14c dt-bindings: usb: fsa4480: Add data-lanes property to endpoint
Allow specifying data-lanes to reverse the muxing orientation between
AUX+/- and SBU1/2 where necessary by the hardware design.

In the mux there's a switch that needs to be controlled from the OS, and
it either connects AUX+ -> SBU1 and AUX- -> SBU2, or the reverse: AUX+
-> SBU2 and AUX- -> SBU1, depending on the orientation of how the USB-C
connector is plugged in.

With this data-lanes property we can now specify that AUX+ and AUX-
connections are swapped between the SoC and the mux, therefore the OS
needs to consider this and reverse the direction of this switch in the
mux.

01afa882f1 dt-bindings: usb: Add binding for fcs,fsa4480
The Fairchild/ON Semiconductor FSA4480 Analog Audio switch is used in
USB Type-C configurations for muxing analog audio onto the USB
connector, and as such used to control the SBU signals for altmodes such
as DisplayPort.

Add a binding for this hardware block.
