If our port-partner supports both DP-only operation (pin-assignment C)
and multi-func operation (pin-assignment D) and we only support
pin-assignment D and the port-partner prefers DP-only mode, then
before this commit we would and up masking out pin-assignment D from
the available pin-assignments and fail to pick a pin-assignment.
Instead only mask out the multi-func pin-assignments if we support
dp-only pin-assignments, so that we correctly fall-back to a multi-func
pin-assignment in this case (by picking pin-assignment D).

"vdev" points to vhci_hcd->vdev[] array and vhci_hcd->vdev[] array
is not a pointer array but a structure array and it is already used
in vhci_urb_enqueue() and then passed to vhci_tx_urb() as an argument.
vhci_tx_urb() is not called except vhci_urb_enqueue(). So, "vdev"
can not be null pointer. This null check statement is meaningless.

As all the memblock allocation functions return NULL in case of error
rather than panic(), the duplicates with _nopanic suffix can be removed.

Refactor the code in charge of looking up the USB PHY when no platdata
is provided. Attempt to get a generic USB PHY first, then look for a
legacy USB PHY through device-tree and finally get any registered PHY
with the correct type.
This way, only a single USB PHY is obtained and the flow is easier to
understand and follow.
All error pointers (except for EPROBE_DEFER) are considered as PHY
not found.

According to the chipidea driver bindings, the USB PHY is specified via
the "phys" phandle node. However, this only takes effect for USB PHYs
that use the common PHY framework. For legacy USB PHYs, a simple lookup
based on the USB PHY type is done instead.
This does not play out well when more than one USB PHY is registered,
since the first registered PHY matching the type will always be
returned regardless of what the driver was bound to.
Fix this by looking up the PHY based on the "phys" phandle node.
Although generic PHYs are rather matched by their "phys-name" and not
the "phys" phandle directly, there is no helper for similar lookup on
legacy PHYs and it's probably not worth the effort to add it.
When no legacy USB PHY is found by phandle, fallback to grabbing any
registered USB2 PHY. This ensures backward compatibility if some users
were actually relying on this mechanism.

This patch adds support to set the power line polarity for i.MX SoCs.
To let the USB controller control the power it may be necessary to
configure the polarity of the power line. So far the polarity was
configured by Bootloader or alternatively the power line was muxed
as gpio and driven by a regulator.
Also make use of of_property_read_bool.

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.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable len is not necessary, hence
it is removed.

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.
