Subject: [PATCH 2/2] ARM: dts: am57xx-evm: Add 'gpios' property with gpio2_8
Date: Tue, 28 Jul 2015 19:09:10 +0530 [thread overview]
Message-ID: <1438090750-11604-3-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1438090750-11604-1-git-send-email-kishon@ti.com>
gpio2_8 is connected to the PCIe_RESETn line and it has to be driven low
in order to reset the PCIe cards. So added gpios property to pcie
dt node.
