This depends on the subsystem the driver will use. For eg. IIO or USB. Accordingly
it the patches should be generated on top of the said subsystem maintainer's branch.
So for USB it will be greg's usb git branch.

What do you mean here?

This depends. If you were to be writing a NAND driver, you would have to provide
mtdtests results.

Some predefined configs should be build checked.

Of course!!!! How else will you submit your work? Run getmaintainers.pl on
your patchset.

Coding conventions can be checked with checkpatch.pl. The rest is suppose
to be non existent in the driver you write!!!!
