I discovered that you can decompile dtb file ^^ => dtc -O dts -I dtb -o am335x-boneblack.dts am335x-boneblack.dtb
the dtb file is the input and the dts file is the output ^^ .
I attached the file generated with this command.
I can find the pruss definition :
pruss@4a300000 {
compatible = "ti,pruss-v2";
ti,hwmods = "pruss";
ti,deassert-hard-reset = "pruss", "pruss";
reg = <0x4a300000 0x80000>;
ti,pintc-offset = <0x20000>;
interrupt-parent = <0x1>;
status = "okay";
interrupts = <0x14 0x15 0x16 0x17 0x18 0x19 0x1a 0x1b>;
pinctrl-names = "default";
*pinctrl-0 = <0x31>;*
linux,phandle = <0xa2>;
phandle = <0xa2>;
};
and the line with pinctrl-0 = <0x31>; means that it is linked with that :
pinmux_pru_pru_pins {
pinctrl-single,pins = <0x158 0x72 0x15c 0x72>;
linux,phandle = <*0x31*>;
phandle = <*0x31*>;
};
But I still don't understand what this error message mean :
[ 6.745295] pruss_uio 4a300000.pruss: No children
