[RFC PATCH 0/3] Use basic_mmio_gpio to implement a generic gpio chip

From: Jamie Iles
Date: Wed May 04 2011 - 11:07:50 EST


This series is based on my earlier set of GPIO patches[1] to extend the
basic_mmio_driver to be used as a library to implement a more generic gpio
chip as initially implemented by Anton Vorontsov[2].

I've modified Anton's patch slightly to allow the bgpio_chip to be embedded
into another structure and converted two drivers over - bt8xxgpio and
langwell. bt8xxgpio seems to play nicely, but langwell not so much as it
didn't previously use a gpio_chip per bank but it is a nice illustration.

Note that this is the same set of patches as attached in "Re: [PATCHv3 0/7]
gpio: extend basic_mmio_gpio for different controllers" but reposted as a set
of patches for convenience.
