* add dependency on CONFIG_OF and select REGMAP_MMIO (suggested by Paul Cercueil paul@crapouillou.net) * add clk_prepare_enable() (suggested by Paul Cercueil paul@crapouillou.net) * inline jz4780_efuse_read_32bytes() since it is only used once * remove read optimization for full block (suggested by Paul Cercueil paul@crapouillou.net) * simplify calculations for rd_adj and rd_strobe (suggested by Paul Cercueil paul@crapouillou.net) * do calculations for rd_adj and rd_strobe in local variables * fix overflow check (did allow for 5 bit values although register is 4 bit wide) * fixes for yaml (sugested by Andreas Kemnade andreas@kemnade.info)
PATCH V5 2020-02-22 11:25:35: * no longer RFC but PATCH * add yaml bindings (by Andreas Kemnade andreas@kemnade.info) * fixes to yaml (suggested by Rob Herring robh@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@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
https://lore.kernel.org/patchwork/cover/868157/
("[v2,0/2] Add efuse driver for Ingenic JZ4780 SoC")
Original authors were PrasannaKumar Muralidharan prasannatsmkumar@gmail.com Mathieu Malaterre malat@debian.org
and there are additions / code improvements by H. Nikolaus Schaller hns@goldelico.com Paul Cercueil paul@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 checkpatched.
