Subject: [PATCH 04/10] ARM: dts: rockchip: add startup delay to rk3288-veyron panel-regulators
Date: Fri, 18 Mar 2016 02:40:00 +0100 [thread overview]
Message-ID: <1458265206-15733-5-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1458265206-15733-1-git-send-email-heiko@sntech.de>
The panels need a bit of time to actually turn on. If this isn't
observed, this results in problems when trying talk to the panels
and thus produces detection errors. 100ms seem to be a safe value
for the time being.
