[PATCH v3 0/2] tc358767 test mode
From: Andrey Smirnov
Date: Mon Dec 09 2019 - 00:10:58 EST
Everyone:
This series is a couple of patches exposing TestCtl register of
tc358767, which can be pretty handy when troubleshooting link problems.
Changes since [v2]:
- Series rebased on 5.4 kernel
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
