We want to migrate from Raspbian to FreeBSD and we need to have a RTC hdw, for our product Kronometrix. One more thing, still a bit unclear to me: should I modify the sys/boot/fdt/dts/arm/rpi2.dts or sys/boot/fdt/dts/arm/bcm2836.dtsi Im now recompiling the kernel after I have modified the rpi2.dts, as Jukka pointed out. I did add to the sys/boot/fdt/dts/arm/rpi2.dts Jukka's patch, for ds1307. Worked fine. (built the fbt table file and install it under /boot/msdos) -- Stefan Parvu <sparvu@kronometrix.org>
