gpio: New driver for LSI ZEVIO SoCs
This driver supports the GPIO controller found in LSI ZEVIO SoCs. It has been successfully tested on a TI nspire CX calculator. Signed-off-by: Fabian Vogt <fabian@ritter-vogt.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

+Zevio GPIO controller
+Required properties:
+- compatible: Should be "lsi,zevio-gpio"
+- reg: Address and length of the register set for the device
+- #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.
+ gpio: gpio@90000000 {
