* no longer RFC but PATCH
* add yaml bindings (by Andreas Kemnade <andreas at kemnade.info>)
* fixes to yaml (suggested by Rob Herring <robh at kernel.org>)

RFC V4 2020-02-17 17:55:35:
* removed read_only for nvmem config because there is no write method
* Kconfig: replaced depends MACH_JZ4780 with MACH_INGENIC
* run through checkpatch and fixed issues
* made use of devm_nvram_register() and get rid of jz4780_efuse_remove()
  (suggested by Srinivas Kandagatla <srinivas.kandagatla at linaro.org>)
* squashed previous patch 1/9 and 2/9 into single (regmap based) driver

RFC V3 2020-02-16 20:20:59:

This series is based on and a follow up for


("[v2,0/2] Add efuse driver for Ingenic JZ4780 SoC")

Original authors were
PrasannaKumar Muralidharan <prasannatsmkumar at gmail.com>
Mathieu Malaterre <malat at debian.org>

and there are additions / code improvements by
H. Nikolaus Schaller <hns at goldelico.com>
Paul Cercueil <paul at crapouillou.net>

This setup works, if the dm9000 driver is compiled
as a module.

Therefore it is all RFC level. It is also not completely
