Subject: ath79: calibrate dlink dir-825 b1 with nvmem
X-Git-Tag: v23.05.0-rc1~666
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=de3d60b982c7b8e1821b90b312db57287e74ede3;p=openwrt%2Fopenwrt.git

ath79: calibrate dlink dir-825 b1 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, only ethernet devices uses the mac address of
"mac-address-ascii" cells, while PCI ath9k devices uses the mac address
within calibration data.

(restored switch configuration in 02_network, integrated caldata into
partition)
