Subject: ath79: convert WiFis based on ar7241_ubnt_unifi.dtsi to nvmem-cells
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=af5306ba70733f7e736b0aef582fb93519fccde9;p=openwrt%2Fstaging%2Fnbd.git

ath79: convert WiFis based on ar7241_ubnt_unifi.dtsi to nvmem-cells

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

While working on it remove stale uboot partition label and merge art
into partition node.
