Most of the interesting drivers are blocked on clock and pinctrl drivers and those are going to take me a little while to get cleaned up. Clock and pinctrl aren't needed for basic GPIO to work (all pins start off as GPIOs..) and it makes it possible to actually do something so this series adds everything that is needed for the main GPIO block in these chips. Changes since v1: - Moves the binding header commit before the yaml commit - Fixes the license on the binding header to include BSD-2-Clause - The driver has been reworked to use the gpiolib irqchip functionality as suggested by Linus[0]. I think I got this right. The gpio controller doesn't actually do anything with interrupts itself.. It just happens to have 4 lines that are also wired to lines on one of the interrupt controllers. - Now that the driver is an interrupt controller in it's own right for the gpio lines that have associated interrupts the binding description has been updated to add the interrupt-controller bits and remove the description of the interrupt-names that described how the interrupts used to be passed in.
