Subject: [PATCH 22/70] dt: move guts devicetree doc out of powerpc directory
Move guts devicetree doc to Documentation/devicetree/bindings/soc/fsl/
since it's used by not only PowerPC but also ARM. And add a specification
for 'little-endian' property.

-* Global Utilities Block
-
-The global utilities block controls power management, I/O device
-enabling, power-on-reset configuration monitoring, general-purpose
-I/O signal configuration, alternate function selection for multiplexed
-signals, and clock control.
-
-Required properties:
-
- - compatible : Should define the compatible device type for
- global-utilities.
- Possible compatibles:
- "fsl,qoriq-device-config-1.0"
- "fsl,qoriq-device-config-2.0"
- "fsl,<chip>-device-config"
- "fsl,<chip>-guts"
- - reg : Offset and length of the register set for the device.
-
-Recommended properties:
-
- - fsl,has-rstcr : Indicates that the global utilities register set
- contains a functioning "reset control register" (i.e. the board
- is wired to reset upon setting the HRESET_REQ bit in this register).
-
- - fsl,liodn-bits : Indicates the number of defined bits in the LIODN
- registers, for those SOCs that have a PAMU device.
-
-Examples:
- global-utilities@e0000 { /* global utilities block */
- compatible = "fsl,mpc8548-guts";
- reg = <e0000 1000>;
- fsl,has-rstcr;
- };
-
- guts: global-utilities@e0000 {
- compatible = "fsl,qoriq-device-config-1.0";
- reg = <0xe0000 0xe00>;
- fsl,has-rstcr;
- #sleep-cells = <1>;
- fsl,liodn-bits = <12>;
- };
