Hmm, my board runs an MPC5200B. How can we solve this u16 versus u32 issue for
both CPUs?
In the oftree one need somthing like that:
// PSC1 is ac97
[EMAIL PROTECTED] {
device_type = "sound";
compatible =
"mpc5200b-psc-ac97","fsl,mpc5200b-psc-ac97";
cell-index = <0>; // or <1> if it is PSC2! Very
important!
reg = <2000 100>;
interrupts = <2 2 0>;
interrupt-parent = <&mpc5200_pic>;
};
Don't know if it uses the current correct content.
