[PATCH 00/11] firewire: add tracepoints events for self ID sequence

[Takashi S. <o-t...@sa...>]

Hi,

In core function, the enumeration of self ID sequences is the first step
to build bus topology for the current generation. Currently, 1394 OHCI
driver has a module option to dump the content of self ID sequence, while
it is implemented by printk. My recent work is going to replace such
logging with tracepoints events, and this series of changes is for the
self ID sequence.

The content of self ID sequence is delivered by a kind of phy packet,
and its serialization and deserialization codes exist in both core function
and 1394 OHCI driver. They include some redundancies, and the series of
changes includes some inline helper functions to replace them.

In the series of changes, some KUnit tests are added to check behaviour
of the enumeration and the helper functions.

Takashi Sakamoto (11):
  firewire: core: add enumerator of self ID sequences and its KUnit test
  firewire: core: add helper function to handle port status from self ID
    sequence and its KUnit test
  firewire: core: minor code refactoring for topology builder
  firewire: ohci: minor code refactoring for self ID logging
  firewire: core: use helper functions for self ID sequence
  firewire: ohci: use helper functions for self ID sequence
  firewire: core: add common inline functions to serialize/deserialize
    self ID packet
  firewire: core: use helper inline functions to deserialize self ID
    packet
  firewire: ohci: use helper inline functions to serialize/deserialize
    self ID packet
  firewire: core: arrangement header inclusion for tracepoints events
  firewire: core: add tracepoints event for self_id_sequence
