Hmm, why don't get rid of phy_mask totally and just return the
new mask in update_hpd() function? Or add a get_hpd_status()
callback. (I also think there are too many callbacks. For example
we could have: setup, set_status, clear and then just use
parameters when needed:
    void setup(bool force, bool disabled, bool rxsense)
    void set_status(bool enable, bool enable_ints)
    void clear()

What do you think? I only checked quickly the code, don't know if
this is enough.

Best regards,
