I'm trying to set the bus speed for i2c-2 to 400000. I'm running kernel
4.4.68-ti-r107 on a Beaglebone Black. So farI've tried
1. modifying am335x-boneblack.dtb to set the speed to 400000
2. recompiling the kernel (after modifying i2c-core.c).
in i2c_parse_fw_timings() i set t->bus_freq to 400000 explicitly.
Neither of these had any affect on the bus speed.
I've been searching for a couple days, and can't see another way to do it,
can the bus speed actually be changed somehow?
Thanks
Joe
