From 79107116d115c4d96c5cd0446c11b3751e597fce Mon Sep 17 00:00:00 2001 From: Edward Chow Date: Sat, 5 Nov 2022 14:29:03 +0800 Subject: [PATCH] ath79: calibrate TL-WDR4900 v2 with nvmem-cells Driver for both soc (2.4GHz Wifi) and pci (5 GHz) now pull the calibration data from the nvmem subsystem. This allows us to move the userspace caldata extraction for the pci-e ath9k supported wifi into the device-tree definition of the device. wmac's nodes are also changed over to use nvmem-cells over OpenWrt's custom mtd-cal-data property.
