Revision 8e37395c3a5dceff62a5010ebbbc107f4145935c authored by Linus Torvalds on 20 October 2021, 16:13:22 UTC, committed by Linus Torvalds on 20 October 2021, 16:13:22 UTC
Pull sound fixes from Takashi Iwai:
 "Again it became bigger than wished, unfortunately, as this contains
  quite a few ASoC fixes that came up a bit late. It also includes yet
  more HD- and USB-audio quirks: I decided to merge them now, as those
  are for stable, and we'll need them sooner or later.

  Although the volumes are a bit high, all changes are device-specific
  (and reasonably small) fixes, so it should be safe for the late rc"

Description
-----------

This driver supports hardware monitoring for National Semiconductor / TI LM25056,
LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring,
Control, and Protection ICs.

The driver is a client driver to the core PMBus driver. Please see
Documentation/hwmon/pmbus.rst for details on PMBus client drivers.


Usage Notes
-----------

This driver does not auto-detect devices. You will have to instantiate the
devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
details.


Platform data support
---------------------

The driver supports standard PMBus driver platform data.
