Dear Wolfgang,

As you can see in http://patchwork.ozlabs.org/patch/120771/ message archive I did a send without v3 tag and changelog by mistake. The latest version with tag and changelog is
http://patchwork.ozlabs.org/patch/120777/.

Cheers
Dirk

Hi Dirk,

Perhaps its easiest if you could send an incremental patch, to bring the upstream source to the latest one. As your new PPC4xx board support depends on the new API.

Otherwise Wolfgang would need to revert the patch 486cad03be46114d726df56721ee27cba52c38e3 and apply the new one.

Wolfgang, what would you prefer? Should Dirk just send an incremental patch?

Best regards,
Stefan
