[RFC v4 0/6] MIPS: CI20: Add efuse driver for Ingenic JZ4780 and attach to DM9000 for stable MAC addresses

From: H. Nikolaus Schaller
Date: Mon Feb 17 2020 - 11:55:44 EST

* 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


("[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

H. Nikolaus Schaller (1):
MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the
default MAC address

PrasannaKumar Muralidharan (5):
nvmem: add driver for JZ4780 efuse
Bindings: nvmem: add bindings for JZ4780 efuse
Documentation: ABI: nvmem: add documentation for JZ4780 efuse ABI
nvmem: MAINTAINERS: add maintainer for JZ4780 efuse driver
MIPS: DTS: JZ4780: define node for JZ4780 efuse
