Given an ethernet MAC configuration struct, load a MAC address into a provided array. Signed-off-by: Pieter De Gendt <[email protected]>
Turn ethernet controller devicetree nodes into NVMEM consumers. Allow passing mac-address cells. Signed-off-by: Pieter De Gendt <[email protected]>
Rework the Atmel SAM GMAC driver to read a MAC address from the provided NVMEM cell instead of using I2C commands directly. Signed-off-by: Pieter De Gendt <[email protected]>
Create a generic Wi-Fi interface binding file which includes the ethernet-controller.yaml bindings and include it in Nordic's WLAN interface binding. Signed-off-by: Pieter De Gendt <[email protected]>
Allow setting the MAC address for the nRF Wi-Fi interface with a configuration derived from the devicetree. This allows to use an NVMEM cell as MAC address storage. Signed-off-by: Pieter De Gendt <[email protected]>
