7bae0432a6 usb: core: add option of only authorizing internal devices
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.

8a863a608d usb: typec: tps6598x: handle block writes separately with plain-I2C adapters
Commit 1a2f474d32 handles block _reads_ separately with plain-I2C
adapters, but the problem described with regmap-i2c not handling
SMBus block transfers (i.e. read and writes) correctly also exists
with writes.

As workaround, this patch adds a block write function the same way
1a2f474d32 adds a block read function.

Fixes: 1a2f474d32 ("usb: typec: tps6598x: handle block reads separately with plain-I2C adapters")

Make use of the struct_size() helper instead of an open-coded version

So, change the following form:

to :

struct_size(packet_status, PacketStatus, seg->isoc_frame_count);

5ebf5c8903 usb: core: config: Use struct_size() in kzalloc()
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.

80e04837a4 device connection: Prepare support for firmware described connections
When the connections are defined in firmware, struct
device_connection will have the fwnode member pointing to
the device node (struct fwnode_handle) of the requested
device. The endpoint member for the device names will not be
used at all in that case.

393cd68d0d platform/x86: intel_cht_int33fe: Remove old style mux connections
The new mux connection naming scheme is now in use, so
dropping the connections still using the old names. From now
on the same connection description named "mode-switch" is
used with both the port and the alternate modes, so on CHT
the DP alt mode will use the same connection as the port to
get a handle to the mux device.

540bfab7fb usb: typec: Rationalize the API for the muxes
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.

d2fce70175 USB: musb: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/usb/musb/musb_host.c: In function ‘musb_advance_schedule’:
drivers/usb/musb/musb_host.c:374:7: warning: this statement may fall through [-Wimplicit-fallthrough=]

       ^
drivers/usb/musb/musb_host.c:383:3: note: here
   case USB_ENDPOINT_XFER_ISOC:
   ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

The Kconfig entry previously depended on USB_OTG_BLACKLIST_HUB
unconditionally, which is an option that is only available when
CONFIG_USB is enabled. However, the USB IP in the JZ4740 SoC does not
support host mode, only gadget mode, so it makes sense to allow it to
build when CONFIG_USB is not set.
