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?
