[PATCH v2 0/2] tc358767 test mode

[Andrey Smirnov]

Everyone:

This series is a couple of patches exposing TestCtl register of
tc358767, which can be pretty handy when troubleshooting link problems.

Changes since [v1]:

    - Debugfs moved into a standalone directory and is now created as
      a part of probe()

    - Added tstctl_lock to ensure mutual exclusion of tstctl code and
      bridge's enable/disable methods

    - tc_tstctl_set() changed to function only if bridge was previosly
      enabled

    - Added comment explaining data format expected by "tstctl"

    - Debugfs permission changed to reflect write-only nature of this
      feature

    - Original commit split into two

    - Minor formatting changes

Thanks,
Andrey Smirnov
