Subject: [PATCH 0/7] New eFuse subsystem
Date: Wed, 25 Feb 2015 08:45:12 -0300	[thread overview]
Message-ID: <1424864719-3390-1-git-send-email-ezequiel.garcia@imgtec.com> (raw)

This patchset introduces a new driver subsystem, meant to support eFuse
(alias OTP, one-time-programmable) devices.

The motivation behind this work is to have a common place for drivers
that are currently more or less scattered: the tegra efuses are in
drivers/soc/ and the sunxi efuses in drivers/misc/eeprom.

For now, there's no proposal for a generic efuse API. Instead, we simply
group the drivers together.

This patchset is the result of the initial submission for IMG Pistachio
eFuse support [1]. Our first proposal was to follow the Tegra efuse, and
put the Pistachio efuse in drivers/soc. After some discussion we finally
agreed [2] to first create an efuse directoy, and then put all efuse drivers
in it.

As always, all comments are welcome!
