Because the actual reg value of the peci bus is reg = <0x0 0x60> but
anyway it's an example.

No 'reg' property?
0 is fine, but you really should have a 'reg' property.
This is the actual peci bus node which is a parent of this MFD node:
peci0: peci-bus@0 {
compatible = "aspeed,ast2500-peci";
reg = <0x0 0x60>;
#address-cells = <1>;
#size-cells = <0>;
interrupts = <15>;
clocks = <&syscon ASPEED_CLK_GATE_REFCLK>;
resets = <&syscon ASPEED_RESET_PECI>;
clock-frequency = <24000000>;
msg-timing = <1>;
addr-timing = <1>;
rd-sampling-point = <8>;
cmd-timeout-ms = <1000>;
};

Remove this.
I dropped all other properties into < more properties > because I want
to show the #address-cells and #size-cells to state its sub-nodes
should have a single unique reg value. Should I remove this line or the
whole parent node?
Just drop the properties which are unimportant for the example. You
do not need to replace them with anything, especially with a non-DT
compliant string.
