00:29 <zmatt> blathijs: this is a fine example where the kernel maintainer is just a fucking idiot

00:33 <zmatt> so yeah, mainline added a patch that deliberately broke using the spi:spidev alias (by explicitly double-checking that it matched one of the spidev_dt_ids[] strings) and in response both the rpi and the bbb kernels undid that change (bbb simply reverted that patch while rpi added "spidev" to spidev_dt_ids)

00:34 <zmatt> since newsflash, spi is a perfectly normal way to communicate with devices that don't have nor need a kernel driver, including application-specific communication with microcontrollers
