Sharp lq101r1sx01 panel works as left-right gang mode. So link2
should send cmds like "exit sleep mode", "set display on"
to panel as well.

What's the changelog v1->v2?

I expect you should CC the DRM list and maintainer too?

I've talked with Thierry about this. The patch doesn't make sense for
now. So please ignore it, thanks Stephen/Thierry.
