Subject: [PATCH] net: macb: Add default usrio config to default gem config
Date: Mon, 11 Jan 2021 11:55:53 -0800	[thread overview]
Message-ID: <20210111195553.3745008-1-atish.patra@wdc.com> (raw)

There is no usrio config defined for default gem config leading to
a kernel panic devices that don't define a data. This issue can be
reprdouced with microchip polar fire soc where compatible string
is defined as "cdns,macb".

Fixes: edac63861db7 ("add userio bits as platform configuration")
