Dunno, looks abandoned, so let me grab this. If anyone else wants to pick it up, let me know. Applied, thanks!

Adrian, IMHO, this driver should go through the SH tree. Thanks Rob, for testing the patch.

The J2 SPI controller bindings never allowed spi-max-frequency property in the controller node. Neither old spi-bus.txt bindings, nor new DT schema allows it. Linux driver does not parse that property from controller node, thus drop it from DTS as incorrect hardware description. The SPI child device has already the same property with the same value, so functionality should not be affected.
