Subject: mediatek: drop spi cal for Keenetic KN-(3711/3811/3911)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=299105441a55cf12574d1e7ea04c02ddb4f22367;p=thirdparty%2Fopenwrt.git

mediatek: drop spi cal for Keenetic KN-(3711/3811/3911)

In the original DTS from the device firmware, there are
no entries that enable SPI calibration. Therefore, it
should be disabled.
