Subject: [PATCH 3/3] ARM: dts: imx6*-hummingboard: fix pcie reset GPIO specification
Date: Wed, 27 Jan 2016 20:24:01 +0000 [thread overview]
Message-ID: <E1aOWdF-00058a-0X@rmk-PC.arm.linux.org.uk> (raw)
PCIe reset signals are active low, and our GPIO for this is directly
connected to the PCIe reset. However, as the PCIe driver does not use
the flag, the specification of '0' flags (which means active high) has
not been noticed. Correct this oversight, and switch to using the
GPIO flag definitions instead.
