Subject: [PATCH net-next 3/3] of_net: add property "nvmem-mac-address" for of_get_mac_addr()
Date: Fri, 9 Apr 2021 16:37:51 +0800 [thread overview]
Message-ID: <20210409083751.27750-4-qiangqing.zhang@nxp.com> (raw)
In-Reply-To: <20210409083751.27750-1-qiangqing.zhang@nxp.com>
From: Fugang Duan <fugang.duan@nxp.com>
If MAC address read from nvmem cell and it is valid mac address,
.of_get_mac_addr_nvmem() add new property "nvmem-mac-address" in
ethernet node. Once user call .of_get_mac_address() to get MAC
address again, it can read valid MAC address from device tree in
directly.
