what changed between 3.10 and 3.15 for radeon i2c?

[seeker010]

using 3.10 kernel, lm-sensors detects the i2c chip with the lm64 module and reports temperatures on my x1650xt
using the 3.15 kernel, lm-sensors does not

Nothing in the driver changed. I think the radeon code may have pre-dated the kernel support for lm64 chips. Maybe you were usng an out of tree driver for the lm64? There is no lm64 module in the kernel. Looks like the lm63 module has support for the lm64 chip. You can either manually load the lm63 driver, or try this patch to have radeon autoload lm63:

I can modprobe the kernel module, but it doesn't show any temps.
