Hmm, I just did a quick git grep over arch/arm/boot/dts and could not 
really find the "samsung,<ip>-<chip>" pattern.

Except MFC (and without Padma's patch also I2S), which used "samsung,<ip>-
<ip version>, all the compatible values I can see are based on 
"samsung,<chip>-<ip>" pattern.

I believe we discussed this issue several times already and finally agreed 
to use "samsung,<chip>-<ip>" for any new compatible values.

Best regards,
Tomasz
