Hi,
tc358767 bridge was originally implemented for eDP use with an embedded
panel. I've been working to add DP and HPD support, and this series is
the result. I did have a lot of issues with link training, but with
these, it's been working reliably with my devices.
Changes in v2
* Drop "implement naive HPD handling", and implement HPD interrupt handling.
Changes in v3
* Various small comment, description and formatting changes
* 'hpd-num' DT property renamed to 'toshiba,hpd-pin'
* Check DP0CTL == 0 at the beginning of tc_main_link_enable
* Disable only the video stream in tc_stream_disable()
* Fix tc_connector_detect for eDP panels
