Subject: kernel: b53: use hard coded switch reset gpio on some boards.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cde1d53625ab93fb8ddf3121f33756f36ca1aff5;p=openwrt%2Fstaging%2Fjow.git

kernel: b53: use hard coded switch reset gpio on some boards.

The Linksys wrt310n v1 does not have a robo_reset config variable in
nvram, but GPIO Pin 8 is the pin needed for resetting the external
switch, Linksys hard coded it into their source code.

Thank you Devastator for testing.
