Hi guys
I'm using a lite5200b EVB (u-boot 1.2, kernel 2.6.26.3), using the psc-spi
driver and the mmc-spi driver.
I've modified the lite5200b.dts file, I'd have SPI on PSC6 and mmc_spi
connected to SPI on PSC6
first I've commented
// [EMAIL PROTECTED] {
// compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
// reg = <0xf00 0x20>;
// interrupts = <2 13 0 2 14 0>;
// interrupt-parent = <&mpc5200_pic>;
// };
and then uncommented
// PSC6 in spi mode example
[EMAIL PROTECTED] { // PSC6
compatible =
"fsl,mpc5200b-psc-spi","fsl,mpc5200-psc-spi";
cell-index = <5>;
reg = <0x2c00 0x100>;
interrupts = <2 4 0>;
interrupt-parent = <&mpc5200_pic>;
[EMAIL PROTECTED] {
linux,modalias = "mmc_spi";
};
};
I've also added a node to [EMAIL PROTECTED] (I'm not sure about last change).
My question are:
a) Is this the right way to insert a node in device tree (in this example for
mmc-spi) or there are an other way to pass the information to mmc-spi that SPI
is on PSC6?
b) Why in /proc/devices I do not see any spi device (mpc5200b-psc-spi) or
something like that?
Adding some printk I have:
Fun = mpc52xx_psc_spi_init Ret = 0
Is my of_register_platform_driver was ok.
c) BTW a Block device mmc in /proc/devices is added (not mmc-spi as I'm
waiting), if I try to create a node and then write on device nothing happens.
Any suggestion?
Thanks J
