From 5f104178bf713615dc404fdfcf0fb53d89c66a07 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Tue, 28 Nov 2017 17:56:12 +0100 Subject: [PATCH] rockchip: dts: rk3399-puma: add /config/sysreset-gpio property On the RK3399-Q7, we want to trigger a full platform reset (so the various software stacks supported don't have to deal with the same complexities over and over again) in case that anything other than a power-on reset occurred. To do so, this defines the /config/sysreset-gpio property and has it point to a GPIO that will perform a power-on reset of the entire platform.
