This is a proposed power sequencer subsystem. This is a
generification of the MMC pwrseq code. The subsystem tries to abstract
the idea of complex power-up/power-down/reset of the devices.

The primary set of devices that promted me to create this patchset is
the Qualcomm BT+WiFi family of chips. They reside on serial+platform
or serial + SDIO interfaces (older generations) or on serial+PCIe (newer
generations).

Instead of older and newer, it would be more unstandable to mention
specific chips. For example I have no clue what you mean with older
generation.
