Merge tag 'usb-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt / PHY driver updates from Greg KH: "Here is the big set of USB, Thunderbolt, and PHY driver updates for 6.6-rc1. Included in here are: - PHY driver additions and cleanups - Thunderbolt minor additions and fixes - USB MIDI 2 gadget support added - dwc3 driver updates and additions - Removal of some old USB wireless code that was missed when that codebase was originally removed a few years ago, cleaning up some core USB code paths - USB core potential use-after-free fixes that syzbot from different people/groups keeps tripping over - typec updates and additions - gadget fixes and cleanups - loads of smaller USB core and driver cleanups all over the place Full details are in the shortlog.

-Description:
- Various files for managing Cable Based Association of
- (wireless) USB devices.
-
- The sequence of operations should be:
-
- 1. Device is plugged in.
-
- 2. The connection manager (CM) sees a device with CBA capability.
- (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
-
- 3. The CM writes the host name, supported band groups,
- and the CHID (host ID) into the wusb_host_name,
- wusb_host_band_groups and wusb_chid files. These
- get sent to the device and the CDID (if any) for
- this host is requested.
-
- 4. The CM can verify that the device's supported band
- groups (wusb_device_band_groups) are compatible
- with the host.
-
- 5. The CM reads the wusb_cdid file.
-
- 6. The CM looks it up its database.
-
- - If it has a matching CHID,CDID entry, the device
- has been authorized before and nothing further
- needs to be done.
-
- - If the CDID is zero (or the CM doesn't find a
- matching CDID in its database), the device is
- assumed to be not known. The CM may associate
- the host with device by: writing a randomly
- generated CDID to wusb_cdid and then a random CK
- to wusb_ck (this uploads the new CC to the
- device).
-
- CMD may choose to prompt the user before
- associating with a new device.
-
- 7. Device is unplugged.

+21. MIDI2 function
+==================
+
+The function is provided by usb_f_midi2.ko module.
+It will create a virtual ALSA card containing a UMP rawmidi device
+where the UMP packet is looped back. In addition, a legacy rawmidi
+device is created. The UMP rawmidi is bound with ALSA sequencer
+clients, too.
+
+Function-specific configfs interface
+------------------------------------
+
+The function name to use when creating the function directory is "midi2".
+The midi2 function provides these attributes in its function directory
+as the card top-level information:
+
+ ============= =================================================
+ process_ump Bool flag to process UMP Stream messages (0 or 1)
+ static_block Bool flag for static blocks (0 or 1)
+ iface_name Optional interface name string
+ ============= =================================================
+
+The directory contains a subdirectory "ep.0", and this provides the
+attributes for a UMP Endpoint (which is a pair of USB MIDI Endpoints):
+
+ ============= =================================================
+ protocol_caps MIDI protocol capabilities;
+ 1: MIDI 1.0, 2: MIDI 2.0, or 3: both protocols
+ protocol Default MIDI protocol (either 1 or 2)
+ ep_name UMP Endpoint name string
+ product_id Product ID string
+ manufacturer Manufacture ID number (24 bit)
+ family Device family ID number (16 bit)
+ model Device model ID number (16 bit)
+ sw_revision Software revision (32 bit)
+ ============= =================================================
+
+Each Endpoint subdirectory contains a subdirectory "block.0", which
+represents the Function Block for Block 0 information.
+Its attributes are:
+
+ ================= ===============================================
+ name Function Block name string
+ direction Direction of this FB
+ 1: input, 2: output, or 3: bidirectional
+ first_group The first UMP Group number (0-15)
+ num_groups The number of groups in this FB (1-16)
+ midi1_first_group The first UMP Group number for MIDI 1.0 (0-15)
+ midi1_num_groups The number of groups for MIDI 1.0 (0-16)
+ ui_hint UI-hint of this FB
+ 0: unknown, 1: receiver, 2: sender, 3: both
+ midi_ci_verison Supported MIDI-CI version number (8 bit)
+ is_midi1 Legacy MIDI 1.0 device (0-2)
+ 0: MIDI 2.0 device,
+ 1: MIDI 1.0 without restriction, or
+ 2: MIDI 1.0 with low speed
+ sysex8_streams Max number of SysEx8 streams (8 bit)
+ active Bool flag for FB activity (0 or 1)
+ ================= ===============================================
+
+If multiple Function Blocks are required, you can add more Function
+Blocks by creating subdirectories "block.<num>" with the corresponding
+Function Block number (1, 2, ....). The FB subdirectories can be
+dynamically removed, too. Note that the Function Block numbers must be
+continuous.
+
+Similarly, if you multiple UMP Endpoints are required, you can add
+more Endpoints by creating subdirectories "ep.<num>". The number must
+be continuous.
+
+For emulating the old MIDI 2.0 device without UMP v1.1 support, pass 0
+to `process_ump` flag. Then the whole UMP v1.1 requests are ignored.
+
+Testing the MIDI2 function
+--------------------------
+
+On the device: run the gadget, and running::
+
+ $ cat /proc/asound/cards
+
+will show a new sound card containing a MIDI2 device.
+
+OTOH, on the host::
+
+ $ cat /proc/asound/cards
+
+will show a new sound card containing either MIDI1 or MIDI2 device,
+depending on the USB audio driver configuration.
+
+On both, when ALSA sequencer is enabled on the host, you can find the
+UMP MIDI client such as "MIDI 2.0 Gadget".
+
+As the driver simply loops back the data, there is no need for a real
+device just for testing.
+
+For testing a MIDI input from the gadget to the host (e.g. emulating a
+MIDI keyboard), you can send a MIDI stream like the following.
+
+On the gadget::
+
+ $ aconnect -o
+ ....
+ client 20: 'MIDI 2.0 Gadget' [type=kernel,card=1]
+ 0 'MIDI 2.0 '
+ 1 'Group 1 (MIDI 2.0 Gadget I/O)'
+ $ aplaymidi -p 20:1 to_host.mid
+
+On the host::
+
+ $ aconnect -i
+ ....
+ client 24: 'MIDI 2.0 Gadget' [type=kernel,card=2]
+ 0 'MIDI 2.0 '
+ 1 'Group 1 (MIDI 2.0 Gadget I/O)'
+ $ arecordmidi -p 24:1 from_gadget.mid
+
+If you have a UMP-capable application, you can use the UMP port to
+send/receive the raw UMP packets, too. For example, aseqdump program
+with UMP support can receive from UMP port. On the host::
+
+ $ aseqdump -u 2 -p 24:1
+ Waiting for data. Press Ctrl+C to end.
+ Source Group Event Ch Data
+ 24:1 Group 0, Program change 0, program 0, Bank select 0:0
+ 24:1 Group 0, Channel pressure 0, value 0x80000000
+
+For testing a MIDI output to the gadget to the host (e.g. emulating a
+MIDI synth), it'll be just other way round.
+
+On the gadget::
+
+ $ arecordmidi -p 20:1 from_host.mid
+
+On the host::
+
+ $ aplaymidi -p 24:1 to_gadget.mid
+
+The access to MIDI 1.0 on altset 0 on the host is supported, and it's
+translated from/to UMP packets on the gadget. It's bound to only
+Function Block 0.
+
+The current operation mode can be observed in ALSA control element
+"Operation Mode" for SND_CTL_IFACE_RAWMIDI. For example::
+
+ $ amixer -c1 contents
+ numid=1,iface=RAWMIDI,name='Operation Mode'
+ ; type=INTEGER,access=r--v----,values=1,min=0,max=2,step=0
+ : values=2
+
+where 0 = unused, 1 = MIDI 1.0 (altset 0), 2 = MIDI 2.0 (altset 1).
+The example above shows it's running in 2, i.e. MIDI 2.0.
