Subject: ramips: use NVMEM cells with mt76 EEPROM for Netgear R6220 & WNDR3700 v5
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=03b328480559a0183752f668dece2ff00d3bee28;p=openwrt%2Fstaging%2Fnbd.git

ramips: use NVMEM cells with mt76 EEPROM for Netgear R6220 & WNDR3700 v5

This uses new upstream DT binding. It's more generic (NVMEM) compared to
the old one (MTD).
