Takashi Iwai 177ccf811d ALSA: seq: Support MIDI 2.0 UMP Endpoint port
This is an extension to ALSA sequencer infrastructure to support the
MIDI 2.0 UMP Endpoint port.  It's a "catch-all" port that is supposed
to be present for each UMP Endpoint.  When this port is read via
subscription, it sends any events from all ports (UMP Groups) found in
the same client.

A UMP Endpoint port can be created with the new capability bit
SNDRV_SEQ_PORT_CAP_UMP_ENDPOINT.  Although the port assignment isn't
strictly defined, it should be the port number 0.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
