    [media] st-hva: add debug file system · c610b5a8
    Jean-Christophe Trotin authored
    This patch creates 4 static debugfs entries to dump:
    - the device-related information ("st-hva/device")
    - the list of registered encoders ("st-hva/encoders")
    - the current values of the hva registers ("st-hva/regs")
    - the information about the last closed instance ("st-hva/last")
    
    It also creates dynamically a debugfs entry for each opened instance,
    ("st-hva/<instance identifier>") to dump:
    - the information about the frame (format, resolution)
    - the information about the stream (format, profile, level,
      resolution)
    - the control parameters (bitrate mode, framerate, GOP size...)
    - the potential (system, encoding...) errors
    - the performance information about the encoding (HW processing
      duration, average bitrate, average framerate...)
    Each time a running instance is closed, its context (including the
    debug information) is saved to feed, on demand, the last closed
    instance debugfs entry.
