Subject: drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=625d3b5c2ea612e4adf8b289384ad654c207c2bb;p=openwrt%2Fstaging%2Fblogic.git

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.
