OK, this is not easy, to modify...
My DTS already contains a configuration for the CPM1 port...
ser...@11a00 {
device_type = "serial";
compatible = "fsl,mpc8272-scc-uart",
"fsl,cpm2-scc-uart";
reg = <0x11a00 0x20 0x8000 0x100>;
interrupts = <40 8>;
interrupt-parent = <&PIC>;
fsl,cpm-brg = <1>;
fsl,cpm-command = <0x800000>;
};
ser...@11a60 {
device_type = "serial";
compatible = "fsl,mpc8272-scc-uart",
"fsl,cpm2-scc-uart";
reg = <0x11a60 0x20 0x8300 0x100>;
interrupts = <43 8>;
interrupt-parent = <&PIC>;
fsl,cpm-brg = <4>;
fsl,cpm-command = <0xce0000>;
};
I can't see what I have to do...
This is not obvious ;).
