General PSA (and for Laurent et al, i.e. entire team of people working on all the varios bridge conversions): Please don't make something an error before all in-tree users are converted. Even an informational warning is often too much, even only very few drivers are left using an old pattern. -Daniel > [ 28.567871] omapdrm omapdrm.0: unable to attach bridge /ocp@68000000/dss@48050000/encoder@48050c00 > [ 28.786529] omapdrm omapdrm.0: omap_modeset_init failed: ret=-22 > [ 28.841552] omapdrm: probe of omapdrm.0 failed with error -22 > > This device uses the ti,opa362 chip which did have a dedicated > omapdss driver before (which is removed now) and which seems to > be supported by the simple_bridge now. > > The opa362 is sitting in the video out path from > > omapdrm -> venc -> opa362 -> video-out-connector. > > What does this error mean?
