Hi all,

I'm using linux version 2.6.29-rc5.

I've compiled the SPI diver (spi_mpc83xx.c) as a module, but it fails the l=
oad with a "No such device" error.

I've managed to track it down to platform_driver_probe() in drivers/base/pl=
atform.c=20
which returns -ENODEV because a device list is empty.

Not sure what I'm doing wrong.=20

Part of my device tree is as follows:

	soc8349@e0000000 {
		...
		spi@7000 {
			#address-cells =3D <1>;
			#size-cells =3D <0>;
			compatible =3D "fsl,spi";
			reg =3D <0x7000 0x1000>;
			interrupts =3D <0x10 0x8>;
			interrupt-parent =3D < &ipic >;

			m25p40@2 {
				compatible =3D "m25p80";
				spi-max-frequency =3D <25000000>;
				reg =3D <2>;
			};
		};
		...
	};

Thanks
D
