Merge tag 'firewire-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394

Pull firewire updates from Takashi Sakamoto:
 "This consist of three parts; UAPI update, OHCI driver update, and
  several bug fixes.

  Firstly, the 1394 OHCI specification defines method to retrieve
  hardware time stamps for asynchronous communication, which was
  previously unavailable in user space. This adds new events to the
  UAPI, allowing applications to retrieve the time when asynchronous
  packet are received and sent. The new events are tested in the
  bleeding edge of libhinawa and look to work well. The new version of
  libhinawa will be released after current merge window is closed:

    https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/

  Secondly, the FireWire stack includes a PCM device driver for 1394
  OHCI hardware, This change modernizes the driver by managed resource
  (devres) framework.

  Lastly, bug fixes for firewire-net and firewire-core"
