of_net: remove nvmem-mac-address property

2019-05-10T22:14:29Z

In commit d01f449c008a ("of_net: add NVMEM support to of_get_mac_address") I've added `nvmem-mac-address` property which was wrong idea as I've allocated the property with devm_kzalloc and then added it to DT, so then 2 entities would be refcounting the allocation. So if the driver unbinds, the buffer is freed, but DT code would be still referencing that memory. I'm removing this property completely instead of fixing it, as it's not needed to have it.

of_net: add NVMEM support to of_get_mac_address

2019-05-06T04:47:07Z

Many embedded devices have information such as MAC addresses stored inside NVMEMs like EEPROMs and so on. Currently there are only two drivers in the tree which benefit from NVMEM bindings. Adding support for NVMEM into every other driver would mean adding a lot of repetitive code. This patch allows us to configure MAC addresses in various devices like ethernet and wireless adapters directly from of_get_mac_address, which is already used by almost every driver in the tree. Predecessor of this patch which used directly MTD layer has originated in OpenWrt some time ago and supports already about 497 use cases in 357 device tree files.
