I'm trying to add a couple of drivers to the kernel in a Raspberry pi3

I've got the passing of the config options working, but I'm getting
warnings from the kernel build that the options are not being applied:

/home/gwilson/Qt/Qt-5.9.6/Yocto-build-RPi3/build-raspberrypi3/tmp/work-shared/raspberrypi3/kernel-source/.kernel-meta/configs/Scribe.cfg
Requested value: CONFIG_MAX1363=m
Actual value: # CONFIG_MAX1363 is not set
Config 'MAX1363' has the following conditionals:
I2C (value: "y")
Dependency values are:
I2C [y]
My problem is that I don't understand why the options are not being applied.
For the MAX_9768, it depends on I2C=y which is true. I've run the linux
kernel menu config and when I get to the Sound SOC support none of the
drivers that require I2C support (i.e. 'select SND_SOC_MAX9768 if I2C')
are displayed. I don't see anything else that would disable them, the
other drivers in the SOC Kconfig that don't depend on I2C or that depend
on SPI_MASTER are displayed.
The MAX1363 can be set in the menuconfig to 'm', but still won't set
from the scc, cfg files.
Any insight into what's going on here would be greatly appreciated.
I can help with this ... but first, is this a configuration that I can
build myself ? i.e. what branch, what layers and what extra configs
would I need ?
