On linux-next(on which this patch is based on) I see commit:

    ARM: config: sync multi-v7 config with keystone peripherals

    Signed-off-by: Santosh Shilimkar <santosh.shilimkar@...cle.com>


This commit enables all drivers for K2 platforms including the ones you
mentioned. I added the two missing ones in this patch.
There are some configs related to net which I am not sure whether to
enable or not and how it affects other platforms. But AFAICS, there are
no drivers left to be enabled.
