Subject: [PATCH V4 04/15] ARM: dts: imx6q-dhcom: Adding Wake pin to the PCIe pinctrl
Date: Tue, 29 Jun 2021 15:56:01 +0200	[thread overview]
Message-ID: <20210629135612.60695-4-cniedermaier@dh-electronics.com> (raw)
In-Reply-To: <20210629135612.60695-1-cniedermaier@dh-electronics.com>

The pin CSI0_DATA_EN is reserved for PCIe Wake. Move this pin to
the SoM devicetree. Add PCIe Reset GPIO to the board devicetree.
