Subject: [PATCH v2 2/2] ARM: dts: socfgpa: set bridges status to disabled
Date: Wed, 22 Aug 2018 10:41:10 +0200	[thread overview]
Message-ID: <20180822084110.14969-2-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <20180822084110.14969-1-s.trumtrar@pengutronix.de>

The hps-to-fpga bridges can't be used, when the FPGA is not programmed.
Set the default state to disabled and leave enabling them to the board-specific
dts files.
Although this changes behavior, there are no in-tree users of the bridges, so
this won't break anything.
