No really big feature this time around apart from support to Amlogic

In some places, the code prints a human-readable USB endpoint

Some tcpc device-drivers need to explicitly be told to watch for connection
events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices
being plugged into the Type-C port will not be noticed.
For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to
watch for connection events. Sofar we lack a similar callback to the tcpc
for single-role ports. With some tcpc-s such as the fusb302 this means
no TCPM_CC_EVENTs will be generated when the port is configured as a
single-role port.
This commit renames start_drp_toggling to start_toggling and since the
device-properties are parsed by the tcpm-core, adds a port_type parameter
to the start_toggling callback so that the tcpc_dev driver knows the
port-type and can act accordingly when it starts toggling.
The new start_toggling callback now always gets called if defined, instead
of only being called for DRP ports.
To avoid this causing undesirable functional changes all existing
start_drp_toggling implementations are not only renamed to start_toggling,
but also get a port_type check added and return -EOPNOTSUPP when port_type
is not DRP.

On Chrome OS we want to use USBguard to potentially limit access to USB
devices based on policy. We however to do not want to wait for userspace to
come up before initializing fixed USB devices to not regress our boot
times.
This patch adds option to instruct the kernel to only authorize devices
connected to the internal ports. Previously we could either authorize
all or none (or, by default, we'd only authorize wired devices).
The behavior is controlled via usbcore.authorized_default command line
option.

Since with accessory modes there is no need for additional
identification when requesting a handle to the mux, we can
replace the second parameter that is passed to the
typec_mux_get() function with a pointer to alternate mode
description structure, and simply passing NULL with
accessory modes.
This change means the naming of the mux device connections
can be updated. Alternate and Accessory Modes will both be
handled with muxes named "mode-switch", and the orientation
switches will be named "orientation-switch".
Future identification of the alternate modes will be later
done using device property "svid" of the mux.

USB changes for v4.21
So it looks like folks are interested in dwc3 again. Almost 64% of the
changes are in dwc3 this time around with some other bits in gadget
functions and dwc2.
There are two important parts here: a. removal of the waitqueue from
dwc3's dequeue implementation, which will guarantee that gadget
functions can dequeue from any context and; b. better method for
starting isochronous transfers to avoid, as much as possible, missed
isoc frames.
Apart from these, we have the usual set of non-critical fixes and new
features all over the place.

Add a field frame_number to the usb_request to report the interval
number in (micro)frames in which the isochronous transfer was
transmitted or received. The gadget driver can use this knowledge to
synchronize with the host. Also, this option is useful for debugging
purposes.
