Do you still use the component framework in this patchset?
In the cover letter you write: "- Use of_platform_populate to manage multi hardware, not component framework for patch 4/15"
If that frameworks is not used anymore you should also change the commit log, and maybe this patch is not needed anymore?

Thanks,
