Using SPI in lite5200

[Miguel Angel Alvarez]

Hi.

We are trying to use the SPI subsystem in the MPC5200 to write a driver 
that supports SC16IS752 (SPI->2 UARTs).

Although I have read the spi-summary in the Documentation of the kernel, 
I am not quite sure of having understood all the pieces that I require 
to make the system work.

First of all, I am using the SPI associated to PSC3, so in  the 
mpc52xx_devices.c I have added a "[MPC52xx_PSC_SPI]" entry with exactly 
the same parameters as "[MPC52xx_PSC3]", except for the name, which I 
assign to mpc52xx-psc-spi (I suppose this is the correct driver for the 
master of the SPI bus).

That is:
[MPC52xx_PSC_SPI] = {
        .name        = "mpc52xx-psc-spi",
        .id        = 2,
        .num_resources    = 2,
        .resource    = (struct resource[]) {
            {
                .start    = 0x2400,
                .end    = 0x249f,
                .flags    = IORESOURCE_MEM,
            },
            {
                .start    = MPC52xx_PSC3_IRQ,
                .end    = MPC52xx_PSC3_IRQ,
                .flags    = IORESOURCE_IRQ,
            },
        },
    },

My question is: Am I using the correct IRQ? Where can I find which is 
the correct one?

Thanks

Miguel Ángel
