I don't get this point. The legacy board code for koelsch and lager both create a platform_device with "i2c-rcar_gen2", so the cores surely must be compatible? Maybe the cores are not strictly based on each other, but compatible, yes, I'd say. > So far we've dealt with this by updating the driver and only relying > on the actual SoC name as suffix. OK, for consistency reasons I will resend. --XMCwj5IQnwKtuyBG Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQIcBAEBAgAGBQJTAdKFAAoJEBQN5MwUoCm2q3QP/3vvKPepf5Tr2ZsfHVPINPtN IiRVNct1NDOoX/dgJRiFCxIzThy5+Moidrji8ROuC4F1USy8MmLNaeFPPjQNXRJw +0QlRqxxmWs435R+B6dN5bW3LK9CuVkCBO965Gqpu8CFZBfT55rjl5tmvkcxkzCf 1EDUCFr5Mqo0v8t/AVnCTAnET8TbfztwXM/+dfV0XJCUp99swFe4JEUfHfJ3qzC7 6M/Ynvr8cyShssMSJIROGnwB630/w1iL/B58MZFHJJwDVsoVDARWjLxgViH+X6DR R/vY9wsH00QYZJUw0Hu83XZKqMYiGCXnQ3PusMG9hDbKbxNlaJYcSWuWsqXALajZ ntSlw63a1tBWdJYJo/c4Fl5UudQroNc89rEg7rGBqZg3yrvJp14ITi0MqOgslCkF wmIor7SdBCyjhk3eFL5SRHn3Zl+VqOGOQ/WGG6m4Gk79k7kcYneRCcvlQfZ5sH3R bgibm/6ItNh51k1lHcwDMKus+1AI8rvpObom52wm43TmeKuykl1hnIBb/RaBofdX DB7WOK4bWpES+xPQPzg1MjKclrGc0rAeVbrWo9kOgLHLV76eR6kVsNBd5W90cmP3 hPknEiYIyy2l1u8LWA/2XM7h8HjjtoqTHmCS3Nrh1JYRe/lmsyv+eWjd2i294Ro4 hN8U0rXIjqZzvdpejond =2S0v -----END PGP SIGNATURE----- --XMCwj5IQnwKtuyBG--
