[PATCH v3 0/2] tc358767 test mode

From: Andrey Smirnov
Date: Mon Dec 09 2019 - 00:10:58 EST


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

- Added comment explaining data format expected by "tstctl"

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

- Original commit split into two

- Minor formatting changes
