Subject: [PATCH] dt-bindings: gpio: convert faraday,ftgpio01 to yaml
Converts gpio/faraday,ftgpio010.txt to yaml.
Signed-off-by: Corentin Labbe <clabbe@...libre.com>

This commit will cause arch/arm/boot/dts/moxart-uc7112lx.dts to fail DT validation,
but the GPIO driver need an interrupt so the current moxart DT is incomplete and the error is appropriate.

-Faraday Technology FTGPIO010 GPIO Controller
-
-Required properties:
-
-- compatible : Should be one of
- "cortina,gemini-gpio", "faraday,ftgpio010"
- "moxa,moxart-gpio", "faraday,ftgpio010"
- "faraday,ftgpio010"
-- reg : Should contain registers location and length
-- interrupts : Should contain the interrupt line for the GPIO block
-- gpio-controller : marks this as a GPIO controller
-- #gpio-cells : Should be 2, see gpio/gpio.txt
-- interrupt-controller : marks this as an interrupt controller
-- #interrupt-cells : a standard two-cell interrupt flag, see
- interrupt-controller/interrupts.txt

-Example:
-
-gpio@...00000 {
- compatible = "cortina,gemini-gpio", "faraday,ftgpio010";
- reg = <0x4d000000 0x100>;
- interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;
- gpio-controller;
- #gpio-cells = <2>;
- interrupt-controller;
- #interrupt-cells = <2>;
