Subject: [PATCH net 3/3] dt-bindings: doc: add new properties for of_get_mac_address from nvmem
Date: Fri, 10 May 2019 08:24:06 +0000 [thread overview]
Message-ID: <1557476567-17397-4-git-send-email-fugang.duan@nxp.com> (raw)
In-Reply-To: <1557476567-17397-1-git-send-email-fugang.duan@nxp.com>
Currently, of_get_mac_address supports NVMEM, some platforms
MAC address that read from NVMEM efuse requires to swap bytes
order, so add new property "nvmem_macaddr_swap" to specify the
behavior. If the MAC address is valid from NVMEM, add new property
"nvmem-mac-address" in ethernet node.
Update these two properties in the binding documentation.
