Right now the imx6sl display power domain is automatically shut down during boot so lcd doesn't work at all. This has been broken for a while with old gpc bindings, since nobody noticed fix by converting to new bindings.
Link to v1: https://lkml.org/lkml/2018/6/5/689 There is also a nasty errata here, treat it like on 6qp. Previous version included a patch to improve lcdif power management, but since ERR006287 effectively disables runtime PM for display it is no longer strictly required. This doesn't depend on other GPC patches I sent either, it's an unrelated fix.
