Some LEDs on the board are also accessed this way. The spi-rb4xx driver can be found here: https://git.kernel.org/cgit/linux/kernel/git/broonie/spi.git/log/?h=topic/rb4xx I was a bit quick to pull the trigger on this one: I have some cleanup on the Kconfig and headers. I'll wait a couple of days to submit those, in case anyone has comments on the code. -- Bert Vermeulen bert@biot.com
