I didn't get that far on drm-next with pandaboard. When loading modules, dsi_probe crashes. It is missing runtime_get(). But after adding runtime_get call, it fails and I see:

[ 44.671081] omap_hwmod: dss_dsi2: _wait_target_ready failed: -16
[ 44.677459] omapdss_dsi 58005000.encoder: use pm_runtime_put_sync_suspend() in driver?

Why is dsi2 busy (and what does it even mean)...
