This patch series extends the basic_mmio_gpio driver to support controllers with different register sets and number of GPIOs. There are also changes to configure more at probe time rather than runtime evaluation.
I've tested this on an out-of-tree platform with a Synopsys DesignWare GPIO controller.
Jamie Iles (7): basic_mmio_gpio: remove runtime width/endianness evaluation basic_mmio_gpio: convert to platform_{get,set}_drvdata() basic_mmio_gpio: allow overriding number of gpio basic_mmio_gpio: request register regions basic_mmio_gpio: detect output method at probe time basic_mmio_gpio: support different input/output registers basic_mmio_gpio: support direction registers
