Subject: [PATCH v2 0/2] Fix imx6sl display power domain

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.

  ARM: dts: imx6sl: Convert gpc to new bindings
