Subject: ARM: dts: socfgpa: set bridges status to disabled
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b64ac044ad949711470213550b53bd06684c5a03;p=linux.git

ARM: dts: socfgpa: set bridges status to disabled

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.
