I will check this latter this week...Reading the spi dt-binding it states that the spi slave node is optional. If I remove it like this, then the warning is gone:
Unfortunately, the "slave" node is necessary - the "lwn,bk4" compatible causes the spidev driver to be bound. Use space applications on this system use it to perform SPI transmission. IMHO, removing the node is not a solution - we shall discover why on current next we do see such errors.
