We have i.Mx7's spi in slave configuration using PIO. When we are using spi4 in slave mode, we get a read interrupt and we are able to get data also. But if the same is used for spi1, we donot get any interrupt.


We are not sure why slave configuration for spi4 works but spi1 doesn't work.

We are Linux kernel, which has been provided for i.Mx7d eval board.
