Several devices in mt76x8 subtarget use the following line to set up wmac in their DTS(I) files: ralink,mtd-eeprom = <&factory 0x4> This is strange for several reasons: - They should use mediatek,mtd-eeprom on this SOC - The caldata is supposed to start at 0x0 - The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway, starting from 0x0 - The offset coincides with the default location of the MAC address in caldata Based on the comment inb28e94d4bf("ramips: MiWiFi Nano fixes"), it looks like the author for this device wanted to actually use mtd-mac-address instead of ralink,mtd-eeprom. A check on the same device revealed that actually the MAC address start at offset 4 there, so the correct caldata offset is 0x0. Based on these findings, and the fact that the expected location on this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>" statement from all devices in ramips (being only mt7628an anyway). Thanks to Sungbo Eo for finding and researching this.
