[PATCH 1/2] i.MX6-SabreAuto: DTS: use gpio-hog to enable WEIM-NOR at boot

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




From: Alison Chaiken <alison_chaiken@xxxxxxxxxx>

Create an imx6-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.
