Subject: [PATCH 0/4] nvmem: add and use generic MMIO NVMEM

From: Rafał Miłecki <rafal@...ecki.pl>

MMIO accessible NVMEM devices should be simple enough to allow using a
single binding & driver for them.

I already replaced two existing drivers. With NVMEM layouts introduced I
can also replace Broadcom's NVRAM driver but that work depends on my
pending U-Boot patchset (it provides required helpers).

Rafał Miłecki (4):
  dt-bindings: nvmem: mmio: new binding for MMIO accessible NVMEM
    devices
  nvmem: add generic driver for devices with MMIO access
  nvmem: mtk-efuse: replace driver with a generic MMIO one
  nvmem: uniphier-efuse: replace driver with a generic MMIO one
