X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=21495c92dc176a4615e4ecb7a627fdcb31c3aec5;p=openwrt%2Fstaging%2Fstintel.git

ath79: convert Atheros DB120 WiFis to nvmem-cells

Pull the calibration data from the nvmem subsystem. This allows us to
move userspace caldata extraction into the device-tree definition.
