Subject: [PATCH 0/2] Add efuse driver for Ingenic JZ4780 SoC
Date: Wed, 27 Dec 2017 13:27:00 +0100	[thread overview]
Message-ID: <20171227122722.5219-1-malat@debian.org> (raw)

This patchset bring support for read-only access to the JZ4780 efuse as found
on MIPS Creator CI20.

To keep the driver as simple as possible, it was not possible to re-use most of
the nvmem core functionalities. This driver is not compatible with the original
efuse driver as found in the custom linux kernel from upstream (1), in
particular it does not expose to the users neither:
`/sys/devices/platform/*/chip_id` nor `/sys/devices/platform/*/user_id`.

The goal of this driver is to provide access to the MAC address to the dm9000
driver.
