From 625d3b5c2ea612e4adf8b289384ad654c207c2bb Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Thu, 25 Oct 2018 15:21:31 -0700 Subject: [PATCH] drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM If the HPD signal isn't hooked up to this panel we need a 200 ms delay. In the datasheet this is shown as the maximum time that HPD will take to be asserted after power is given to the panel.
