Hello,
I'm using a customized board similar to the EVM with a DM6446 cpu. The main
difference is that I'm using a Micrel KSZ8893M ethernet switch. The ethernet
switch has an I2C config interface and the standard mdio interface.
Therefore, I'm using the DSA driver subsystem and wrote a small chip driver
(I took the KSZ8893 driver for the Blackfin processor as reference).
Now, my problem is that the ethernet mac of the Davinci cpu is initialized
(probed) later then the DSA driver. And therefore the DSA driver cannot find
a valid netdevice.
Does anyone know how to change the initialization order of the devices??
Changing the order of the register_device_driver function calls has
basically no influence on the init sequence.
Thanks,
Andreas
Hello,
I encounter the same issue with DA830/OMAP-l137 EVM. Instead of
probing PHY to get speed and duplexity, the driver just set the speed
and duplexity based on platform data. May want to take a look at the
OMAP-l137.
Thanks for your answer. I got another solution. The davinci_emac driver
calls the init function very late because of
late_initcall(davinci_emac_init);
I changed this line:
module_init(davinci_emac_init);
Now, it is working!
Cheers,
Andreas
