    1 * Global Utilities Block
    2 
    3 The global utilities block controls power management, I/O device
    4 enabling, power-on-reset configuration monitoring, general-purpose
    5 I/O signal configuration, alternate function selection for multiplexed
    6 signals, and clock control.
    7 
    8 Required properties:
    9 
   10  - compatible : Should define the compatible device type for
   11    global-utilities.
   12    Possible compatibles:
   13         "fsl,qoriq-device-config-1.0"
   14         "fsl,qoriq-device-config-2.0"
   15         "fsl,<chip>-device-config"
   16         "fsl,<chip>-guts"
   17  - reg : Offset and length of the register set for the device.
   18 
   19 Recommended properties:
   20 
   21  - fsl,has-rstcr : Indicates that the global utilities register set
   22    contains a functioning "reset control register" (i.e. the board
   23    is wired to reset upon setting the HRESET_REQ bit in this register).
   24 
   25  - fsl,liodn-bits : Indicates the number of defined bits in the LIODN
   26    registers, for those SOCs that have a PAMU device.
   27 
   28  - little-endian : Indicates that the global utilities block is little
   29    endian. The default is big endian.
   30 
   31 Examples:
   32         global-utilities@e0000 {        /* global utilities block */
   33                 compatible = "fsl,mpc8548-guts";
   34                 reg = <e0000 1000>;
   35                 fsl,has-rstcr;
   36         };
   37 
   38         guts: global-utilities@e0000 {
   39                 compatible = "fsl,qoriq-device-config-1.0";
   40                 reg = <0xe0000 0xe00>;
   41                 fsl,has-rstcr;
   42                 #sleep-cells = <1>;
   43                 fsl,liodn-bits = <12>;
   44         };
