From 2a20dc717a897efe54f241636ee1566b695dbc7d Mon Sep 17 00:00:00 2001 From: Edward Chow Date: Mon, 2 Jan 2023 19:24:20 +0800 Subject: [PATCH] ath79: calibrate dlink dir-825 c1 and dir-835 a1 with nvmem 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. Currently, "mac-address-ascii" cells only works for ethernet and wmac devices, so PCI ath9k device uses the old method to calibrate.
