From 297bceeecf29e9bfedba0b26c9d0a2cefeda2add Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 16 Oct 2021 21:28:52 +0200 Subject: [PATCH] ath79: convert TP-Link Archer C7v1/2 Wifis to nvmem-cells For v2, both ath9k (2.4GHz Wifi) and ath10k (5 GHz) driver now pull the (pre-)calibration data from the nvmem subsystem. v1 is slightly different as only the ath9k Wifi is supported. This allows us to move the userspace caldata extraction and mac-address patching for the 5GHZ ath10k supported wifi into the device-tree definition of the device. ath9k's nodes are also changed over to use nvmem-cells over OpenWrt's custom mtd-cal-data property.
