[qianlihu]

Hi,

I add ipmi kcs node,but it didn't work

here is the patch for dts.

        lpc_bmc: lpc-bmc at 0 {
-               compatible = "aspeed,ast2500-lpc-bmc";
+               compatible = "aspeed,ast2500-lpc-bmc", "simple-mfd", "syscon";
+
                reg = <0x0 0x80>;
+               reg-io-width = <4>;
+
+               #address-cells = <1>;
+               #size-cells = <1>;
+               ranges = <0x0 0x0 0x80>;
+
+               kcs3: kcs3 at 0 {
+                       compatible = "aspeed,ast2500-kcs-bmc";
+                       reg = <0x0 0x80>;
+                       interrupts = <8>;
+                       kcs_chan = <3>;
+                       kcs_addr = <0xca2>;
+                       status = "disabled";
+
+               };
        };

+&kcs3 {
                         +       status = "okay";
        +};
