when i write the following nodes in dts,

uart0: uart at 0xb0060000 {
	compatible = "sirf,uart";
	...
}

uart1: uart at 0xb0050000 {
	compatible = "sirf,uart";
	...
}

uart2: uart at 0xb0070000 {
	compatible = "sirf,uart";
	...
}

then create these platform devices by of_platform_xxx things, i get
some platform devices like the below.

b0060000.uart
b0050000.uart
b0070000.uart

so these are the "stable names" you are talking about? or something else?
