Hi Everyone. I'm trying to get the SPI devices working in the 4.1 kernel, but I don't really want to use the cape manager / overlays. I don't see any dtsi files for the SPI devices in the 4.1 source. The am335x-bone-spi0-spidev.dtsi and am335x-bone-spi1-spidev.dtsi are missing. I had experienced similar issues in the early days of the 3.14 kernel. Perhaps these files need to be updated for the 4.1 kernel?
