Subject: [PATCH v2 0/2] Fix imx6sl display power domain
Date: Mon, 9 Jul 2018 15:23:00 +0300 [thread overview]
Message-ID: <cover.1531138446.git.leonard.crestez@nxp.com> (raw)
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.
