Subject: rockchip: edp: Meet a problem with supporting eDP panel at firefly release
Date: Mon, 16 Jan 2017 23:40:46 +0800 [thread overview]
Message-ID: <1fb3b60b-5a9d-e5c3-41c2-616e6523a41d@soulik.info> (raw)
Hello:
I meet a problem when I want to add support for a lg,lp079qx1-sp0v eDP
panel at firefly release rk3288 platform. I could hardly make the eDP
work both on firefly release and firefly reload. Does you have any idea
about that?
