Subject: [PATCH] ARM: dts: am572x-idk: Add gpios property to control PCIE_RESETn
Date: Fri, 30 Dec 2016 13:37:20 +0530 [thread overview]
Message-ID: <1483085240-16102-1-git-send-email-kishon@ti.com> (raw)
Add 'gpios' property to pcie1 dt node and populate it with
GPIO3_23 in order to drive PCIE_RESETn high.
This gets PCIe cards to be detected in AM572X IDK board.
