We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.

This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices.

pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover regulator and pinctrl
in future. The host driver calls pwrseq_alloc_generic to create
an generic pwrseq instance.

Hi Greg, Sebastian, Dmitry, and David

I find the code under drivers/power have several subsystems.
Does this power sequence patch set can go git://git.infradead.org/battery-2.6.git?
Or can go the Greg's tree?

I think this does not really fit into the power-supply tree.
I would expect this to go through Rafael's linux-pm tree.

Note: I moved all the power-supply code into drivers/power/supply/
in linux-next, among other things because of this patchset. To avoid
merge conflicts in drivers/power/Makefile and drivers/power/Kconfig
the tree pulling this patchset should also pull a (yet to be
created) immutable branch containing
https://git.kernel.org/cgit/linux/kernel/git/sre/linux-power-supply.git/commit/drivers/power?h=for-next&id=8c0984e5a75337df513047ec92a6c09d78e3e5cd
