sys_mpc83xx spi driver not probed

sys_mpc83xx spi driver not probed

[Joel Rouch]

Hello

I have a custom 8349 ppc board. I have defined the spi master in the 
configuration.
While booting my board, I driver is well added and linked to platform 
bus, however I don't see that the probe entry point is reached.
I don't succeed to understand who is triggering the probe. Can someone 
point me to the right link or explain me how to force it ?

Thanks

Are you calling of_platform_bus_probe() from your board file?

Unfortunately not as I still need to use ARCH=ppc.

I am just using a platform_driver_probe() from the module_init.

static int __init mpc83xx_spi_init(void)
{
return platform_driver_probe(&mpc83xx_spi_driver, mpc83xx_spi_probe);

}

Thanks

spi_mpc83xx isn't of_platform_driver, yet. Thus we have to use fsl helper,
fsl_spi_init.

So far, good example of spi_mpc83xx usage is in
arch/powerpc/platforms/83xx/mpc832x_rdb.c


Good luck,
