++3) Generic driver for memory-mapped GPIO controllers
++----------------------------------------------------
++The GPIO generic library provides support for basic platform_device
++memory-mapped GPIO controllers, which can be accessed by selecting Kconfig
++symbol GPIO_GENERIC and using library functions provided by GPIO generic
++driver (see drivers/gpio/gpio-generic.c).
++The simplest form of a GPIO controller that the driver support is just a
++single "data" register, where GPIO state can be read and/or written.
++
++The driver supports:
++- 8/16/32/64 bits registers. The number of GPIOs is determined by the width of
++  the registers.
++- GPIO controllers with clear/set registers.
++- GPIO controllers with a single "data" register.
++- Big endian bits/GPIOs ordering.
++
++For setting GPIO's there are three supported configurations:
++- single input/output register resource (named "dat").
++- set/clear pair (named "set" and "clr").
++- single output register resource and single input resource ("set" and dat").
++
++For setting the GPIO direction, there are three supported configurations:
++- simple bidirection GPIO that requires no configuration.
++- an output direction register (named "dirout") where a 1 bit indicates the
++  GPIO is an output.
++- an input direction register (named "dirin") where a 1 bit indicates the GPIO
++  is an input.
++
++Required properties:
++- compatible : Should be "basic-mmio-gpio".
++- reg : Address and length of the registers needed for the device.
++- reg-names : Names of the needed registers.
++- #gpio-cells : Should be two.  The first cell is the pin number and
++  the second cell is used to specify optional parameters (currently
++  unused).
++- gpio-controller : Marks the device node as a gpio controller.
++
++Optional properties:
++- num-gpios : Specify the number of configurable gpios.
++- bit-be : Use big endian order for pins.
++- byte-be : Use big endian byte order for registers.
++- regset-wo : set register is unreadable.
++- regdir-wo : dir register is unreadable.
++
++Examples:
++
++gpio0: gpio-controller@10000084 {
++	compatible = "brcm,brcm6368", "basic-mmio-gpio";
++	reg = <0x10000084 0x4>, <0x1000008c 0x4>;
++	reg-names = "dirout", "dat";
++
++	gpio-controller;
++	#gpio-cells = <2>;
++
++	num-gpios = <32>;
++	byte-be;
++};
++
++gpio1: gpio-controller@10000180 {
++	compatible = "foo,bar", "basic-mmio-gpio";
++	reg = <0x10000180 0x4>, <0x10000184 0x4>, <0x10000188 0x4>;
++	reg-names = "dirin", "dirout", "dat";
++
++	gpio-controller;
++	#gpio-cells = <2>;
++
++	num-gpios = <20>;
