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
s...@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 s...@2c00 node, much like various I2C devices, etc.
t...@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
