[PATCH v1 2/5] dt-bindings: soc: hpe: Add hpe,gxp-plreg

[Hawkins, Nick]

> I don't know exactly what type of devices you represent in that plreg, but in general the fan device would be the respective plreg. The same with other pieces like hwmon, power supply.
We were primarily representing the registers that translate to the CPLD input/outputs from our platforms as well as handling the interrupts associated with those inputs/outputs. When you say "would be the respective plreg" do you mean that each device/controller would need to perform the actions plreg does individually? In that case how should we get information for that register/memory region and interrupts from the dts? Could it be something like this:

plreg: plreg at d1000000 {
      compatible = "hpe,gxp-plreg";
      reg = <0xd1000000 0xFF>;
      interrupts = <26>;
      interrupt-parent = <&vic0>;
};

fanctrl: fanctrl at c1000c00 {
      compatible = "hpe,gxp-fan-ctrl";
      reg = <0xc1000c00 0x200>;
      plreg_handle = <&plreg>;
};

Thanks for the assistance,
