of_get_mac_address() is commonly used to fetch the MAC address
from the device tree. It also supports reading it from a NVMEM
provider. But the latter is only possible for platform devices,
because only platform devices are searched for a matching device
node.
Add a second method to fetch the NVMEM cell by a device tree node
instead of a "struct device".
Moreover, the NVMEM subsystem will return dynamically allocated
data which has to be freed after use. Currently, this is handled
by allocating a device resource manged buffer to store the MAC
address. of_get_mac_address() then returns a pointer to this
buffer. Without a device, this trick is not possible anymore.
Thus, change the of_get_mac_address() API to have the caller
supply a buffer.
It was considered to use the network device to attach the buffer
to, but then the order matters and netdev_register() has to be
called before of_get_mac_address(). No driver does it this way.
changes since v3:
- use memcpy() instead of ether_addr_copy() where appropriate.
Sometimes the destination is on the stack, thus the 2 byte
alignment requrement is not met.
- fix "return PTR_ERR(mac_addr)" as found by Dan Carpenter
- changed subject of patch 2/2, as suggested by Florian Fainelli
changes since v2:
- fixed of_get_mac_addr_nvmem() signature, which was accidentially
fixed in patch 2/2 again
changes since v1:
- fixed stmmac_probe_config_dt() for !CONFIG_OF
- added missing queue in patch subject

of: net: pass the dst buffer to of_get_mac_address()
of: net: fix of_get_mac_addr_nvmem() for non-platform devices
