From: Alison Chaiken <[email protected]> Create an imx6qdl-sabreauto-weim-nor.dtsi file whose inclusion in a DTS file sets GPIO5 to the level at boot that the WEIM-NOR device requires. The GPIO is set via the gpio-hogging mechanism. Devices whose pinmux needs conflict with those of NOR are disabled.
