Subject: [PATCH 0/7] usb: Add USB MIDI 2.0 Gadget Function Driver
Date: Tue, 25 Jul 2023 08:21:59 +0200 [thread overview]
Message-ID: <20230725062206.9674-1-tiwai@suse.de> (raw)
Hi,
This is a patch set for adding a USB gadget function driver for USB
MIDI 2.0 interface. The MIDI 2.0 support in the host side was already
enabled since 6.5 kernel in snd-usb-audio driver. Now, this provides
a similar gadget functionality using the existing ALSA UMP helper
functions.
The gadget driver provides both MIDI 2.0 and MIDI 1.0 fallback
interfaces with one or more loopback UMP rawmidi devices. The
configfs implementation is flexible enough to allow users to set up
multiple UMP Endpoints and Function Blocks.
The first patch adds the bare f_midi2 driver without configfs support,
followed by the configfs support, MIDI 1.0 interface support and a few
other extensions and documentation.
Takashi
