Linux/AM3358: KSZ9897 Linux driver for AM335x

Hi Harel,

I'm not sure what kernel version you are using and weather the linked KSZ9897 driver is directly applicable but in general you should enable in kernel config parameters described in section 4.1 KSZ9xxx Switch driver setup guide:
github.com/.../KSZ9xxx_Switch_Driver_Setup_Guide.pdf
add described changes in the device tree:
github.com/.../48fa3b0b9aadf25579d6680f935915d69a629593
and copy the driver source code in the ../linux/drivers/ folder.

I See,
If I understand currently , the driver is needed for the "adavanced" features of KSZ9897.
If I work with it as a "standalone" mode , I don't need this specifc driver, just standard RGMII interface.
How do I Configure my linux to work with standard RGMII driver?

Harel,

In general you are right but I'm afraid that KSZ9897 ID specific check will fail if there.
You should set:
CONFIG_MICREL_PHY=y
in your kernel config file to add support for "Giga phys: ksz9021, ksz9031" as it is described in ../drivers/net/phy/micrel.c
