Rob Herring 4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

* Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller
Required properties:
- compatible : Should be "fsl,<soc>-gpio"
The following <soc>s are known to be supported:
mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,
ls1021a, ls1043a, ls2080a.
- reg : Address and length of the register set for the device
- interrupts : Should be the port interrupt shared by all 32 pins.
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify the gpio polarity:
0 = active high
1 = active low
Optional properties:
- little-endian : GPIO registers are used as little endian. If not
present registers are used as big endian by default.
Example of gpio-controller node for a mpc5125 SoC:
gpio0: gpio@1100 {
compatible = "fsl,mpc5125-gpio";
#gpio-cells = <2>;
reg = <0x1100 0x080>;
interrupts = <78 0x8>;
};
Example of gpio-controller node for a ls2080a SoC:
gpio0: gpio@2300000 {
compatible = "fsl,ls2080a-gpio", "fsl,qoriq-gpio";
reg = <0x0 0x2300000 0x0 0x10000>;
interrupts = <0 36 0x4>; /* Level high type */
gpio-controller;
little-endian;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
};
