basic_mmio_gpio: split into a gpio library and platform device
Allow GPIO_BASIC_MMIO_CORE to be used to provide an accessor library for implementing GPIO drivers whilst abstracting the register access detail. Based on a patch from Anton Vorontsov[1] and adapted to allow bgpio_chip to be embedded in another structure. Changes since v1: - Register the gpio_chip in the platform device probe 1. https://lkml.org/lkml/2011/4/19/401 Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com> Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
