[PATCH v5 0/6] MIPS: CI20: Add efuse driver for Ingenic JZ4780 and attach to DM9000 for stable MAC addresses

[H. Nikolaus Schaller]

* no longer RFC but PATCH
* add yaml bindings (by Andreas Kemnade <andreas@xxxxxxxxxxxx>)
* fixes to yaml (suggested by Rob Herring <robh@xxxxxxxxxx>)

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@xxxxxxxxxx>)
* 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

https://lore.kernel.org/patchwork/cover/868157/

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

Original authors were
PrasannaKumar Muralidharan <prasannatsmkumar@xxxxxxxxx>
Mathieu Malaterre <malat@xxxxxxxxxx>

and there are additions / code improvements by
H. Nikolaus Schaller <hns@xxxxxxxxxxxxx>
Paul Cercueil <paul@xxxxxxxxxxxxxxx>

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

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