None of the patches have their git authorship set to the original
authors, nor Signed-off-by lines for them. This information should match
up with the original patches from the RPI Foundation tree, although
sometimes that information is missing there too:-( Please take a look at
Documentation/SubmittingPatches section "12) Sign your work".

Patches should be sent to relevant maintainers and mailing lists.
./scripts/get_maintainers.pl should tell you the relevant people and
lists. In particular, I'd expect the following to be CC'd:

* linux-arm mailing list since this series touches an ARM platform.
* devicetree mailing list since this series touches DT bindings.
* linux-mmc mailing list since this series implements an MMC driver.
* bcm2835 and MMC maintainers.
