must determine correct OS version as the minimum versionprevious overlays tested on 11-STABLE won't work in -CURRENT. need to test in 11-STABLE after the
changes to -CURRENT are back-ported to 11-STABLE, particularly the dtb files for rpi and rpi2 .
tested on an RPi 2 with 11-STABLE (overlay already works on an RPi 1B)
need to test with RPi 3 and with -CURRENT in general, and make changes for the 'compatibility' line in the dts file as neededThis overlay contains fixes for pins for spi0@7e200000 and spi0_cs_pins. Need to test CS==2 on RPi2 to verify it's working.
