Subject: [PATCH] dt-bindings/gpio: Add Aspeed GPIO bindings header
Date: Mon, 31 Oct 2016 15:15:50 +1030 [thread overview]
Message-ID: <20161031044550.1784-1-joel@jms.id.au> (raw)
This provides constants for using GPIOs in the device tree on Aspeed
SoCs.
Signed-off-by: Joel Stanley <joel-U3u1mxZcP9KHXe+LvDLADg@public.gmane.org>

The Apseed GPIO driver and binding document went upstream in 4.9, but we forgot
to send this patch as part of the series.
