Subject: imx: ventana: update imx wdog external reset dt property
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9f0a3ac1b21e3629926e16c523dcb59ff3952c19;p=u-boot.git

imx: ventana: update imx wdog external reset dt property

Early backports of the imx wdog external reset feature occured before the
property was accepted upstream and used 'ext-reset-output' instead of
'fsl,ext-reset-output'. In order to support older kernels remove both
properties.
