Subject: [PATCH] ARM: bcm2835: Give HDMI a HPD GPIO on the pi3
Git-commit: 4df8f031643d949d72ef091396728ea5eab5cf07
Patch-mainline: Queued in subsystem maintainer repository
Git-repo: git://git.kraxel.org/linux
References: FATE#319481
This is the wrong GPIO, but it means vc4 probes and turns on hdmi.
[ kraxel: flip from active low to active high ]
