From: Rafał Miłecki <rafal@xxxxxxxxxx> MMIO accessible NVMEM devices should be simple enough to allow using a single binding & driver for them. In V3 I didn't decide to modify existing Mediatek & UniPhier drivers as there are some concerns about adding writing support to them. If needed that can be done later. Once we get layouts support NVRAM driver will get migrated into one and generic MMIO driver will take over its binding.
