Chipselect in SPI binding with mpc5200-psc-spi

[Henk Stegeman]

In my dts

I have my chipselect defined as follows:

        gpt4: timer at 640 {    // General Purpose Timer GPT4 in GPIO mode for
SMC4000IO chip select.
            compatible = "fsl,mpc5200b-gpt-gpio","fsl,mpc5200-gpt-gpio";
            cell-index = <4>;
            reg = <0x640 0x10>;
            interrupts = <1 13 0>;
            interrupt-parent = <&mpc5200_pic>;
            gpio-controller;
            #gpio-cells = <2>;
        };

I found the gpio in
# cat /sys/class/gpio/gpiochip215/label
/soc5200 at f0000000/timer at 640

The spi controller is defined like this:

        spi at 2400 {
            device_type = "spi";
            #address-cells = <1>;
            #size-cells = <0>;
            compatible = "fsl,mpc5200-psc-spi","fsl,mpc5200b-psc-spi";
            cell-index = <2>;
            reg = <2400 100>;
            interrupts = <2 3 0>;
            interrupt-parent = <&mpc5200_pic>;
            gpios = <&gpt4 0 0>;

            io-controller at 0 {
                compatible = "microkey,smc4000io";
                spi-max-frequency = <1000000>;
                reg = <0>;
            };
        };

At bootup linux (2.6.27) reports:

mpc52xx-psc-spi f0000960.spi: probe called without platform data, no
(de)activate_cs function will be called.

Is my assumption wrong that the gpios property is the way to map chipselects
to the spi driver?

Thanks in advance.
Henk.
