If anyone has any objections, please let me know. ------------------ From: Marijn Suijten [ Upstream commit 2b973ca48ff3ef1952091c8f988d7796781836c8 ] The DSI host must be enabled before our prepare function can run, which has to send its init sequence over DSI. Without enabling the host first the panel will not probe.
