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
