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.
