Subject: ramips: fix pinctrl to allow hardware i2c on WRTNODE2R
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66e2acad9cb0ecada884e58fdeb025f92f2499a3;p=openwrt%2Fstaging%2Fluka.git

ramips: fix pinctrl to allow hardware i2c on WRTNODE2R

Instead of assigning I2C pins as GPIOs by default, leave it up to the
user whether to install kmod-i2c-mt7621 and use them for hardware I2C
instead.
