Hi everyone
I am using ksz8895 and spi .My connection is as below.
Should I have to use dsa drivers.Is my dts file correct?

Hi pavansingpatil๏ผ
I use the RMII and spi mode, the manual says:
MAC/PHY mode in RMII is different than MAC/PHY mode in MII. There is no strap pin and register configuration request
in RMI. Follow the signals connection in Table 3-11.
Hi pavansingpatil๏ผ
Find this directory with the following information
Can you give me some advice?thanks
