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.

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.
Ok, thanks. Rafael, would you agree with that? If you agree, I will update MAINTAINER file.
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
Yes, I found the rebase conflict with it, I will fix it at next revision. -- Best Regards, Peter Chen
