Just to point it out: this is no longer true for SW43408. The panel wakes up and works after toggling the reset. It seems, there is an issue with one of the regulators, but not with the reset and/or panel startup. > Given the apparent prevelance of this issue, particularly with DSC > panels, I believe this is a bug in the core DSI code, and not a device > or panel specific issue.
