    1 * Nuvoton NPCM7xx KCS (Keyboard Controller Style) IPMI interface
    2 
    3 The Nuvoton SOCs (NPCM7xx) are commonly used as BMCs
    4 (Baseboard Management Controllers) and the KCS interface can be
    5 used to perform in-band IPMI communication with their host.
    6 
    7 Required properties:
    8 - compatible : should be one of
    9     "nuvoton,npcm750-kcs-bmc"
   10 - interrupts : interrupt generated by the controller
   11 - kcs_chan : The KCS channel number in the controller
   12 
   13 Example:
   14 
   15     lpc_kcs: lpc_kcs@f0007000 {
   16         compatible = "nuvoton,npcm750-lpc-kcs", "simple-mfd", "syscon";
   17         reg = <0xf0007000 0x40>;
   18         reg-io-width = <1>;
   19 
   20         #address-cells = <1>;
   21         #size-cells = <1>;
   22         ranges = <0x0 0xf0007000 0x40>;
   23 
   24         kcs1: kcs1@0 {
   25             compatible = "nuvoton,npcm750-kcs-bmc";
   26             reg = <0x0 0x40>;
   27             interrupts = <0 9 4>;
   28             kcs_chan = <1>;
   29             status = "disabled";
   30         };
   31 
   32         kcs2: kcs2@0 {
   33             compatible = "nuvoton,npcm750-kcs-bmc";
   34             reg = <0x0 0x40>;
   35             interrupts = <0 9 4>;
   36             kcs_chan = <2>;
   37             status = "disabled";
   38         };
   39     };
