This reg property isn't needed at here because kcs_bmc_aspeed module
reads regmap from the parent node. Please check below code in the
driver code.
priv->map = syscon_node_to_regmap(dev->parent->of_node);

You might need to add kcs4 as a sub-node under lpc_host like below:
kcs4: kcs4@0 {
compatible = "aspeed,ast2500-kcs-bmc";
interrupts = <8>;
kcs_chan = <4>;
status = "disabled";
};
This would be uses as an SMM channel.

Thanks Jay,
I will take care of your comments and send next version.
