MPC5200 SPI

[Gary Thomas]

I'm trying to use the PSC/SPI driver on my MPC5200 board
'drivers/spi/mpc52xx_psc_spi.c' My kernel is 2.6.28, but
I don't see any changes in this area in the latest ones.

Cribbing from the Lite5200, I put this in my DTS file:
		// PSC6 => SPI
		spi at 2c00 {		// PSC6
			compatible = "fsl,mpc5200-psc-spi";
			cell-index = <5>;
			reg = <0x2c00 0x100>;
			interrupts = <2 4 0>;
			interrupt-parent = <&mpc5200_pic>;
		};

I added the SPI device I'm working with (I have to write
this driver, so don't go looking for it).  This was added
within the spi at 2c00 node, much like various I2C devices, etc.

			temp at spi {
				compatible = "maxim,max6629";
			};

Sadly, the SPI master driver seems 100% oblivious to this.
I found the call of_register_spi_devices (drivers/of/of_spi.c),
but it is only used by the xilinx SPI master.  Also, I didn't
find any slave examples anywhere.

Is this driver (SPI on MPC5200) supposed to work?
If so, what am I missing to get it set up?
If not, what needs to be done to get it there?

Thanks
