    Subject[PATCH v2 0/2] staging: pi433: add debugfs interface
    When troubleshooting RF applications, one of the most common approaches 
    is to ensure that both sides of the communication path are using the
    same configuration such as bit rate, frequency deviation, encryption key,
    sync words and so on.

    The existing driver implementation doesn't allow the user to see which
    values have been configured onto the uC which makes trobleshooting more
    painful than it needs to be.

    This patchset adds debugfs interface to this driver and exposes a
    read-only access to uC reg values to address that problem.
