[yocto] Kernel configuration problem/confusion

[Greg Wilson-Lindberg]

I'm trying to add some kernel configuration to a Raspberry pi3 yocto build.  I've got the .cfg fragment being read in, but I'm getting warnings that indicate that they are not making the desired changes.


The first one is CONFIG_SND_SOC_MAX9768. This is a sound codec and the Kconfig file has it in a long list of select's. the one for the MAX9768 is:

    select CONFIG_SND_SOC_MAX9768 if I2C

I2C is set, but CONFIG_SND_SOC_MAX9768 ends up undefined. the warning I'm getting is:

---------- CONFIG_SND_SOC_MAX9768 -----------------
Config: CONFIG_SND_SOC_MAX9768
From: /home/gwilson/Qt-5.9/Yocto-build-RPi3/build-raspberrypi3/tmp/work-shared/raspberrypi3/kernel-source/.kernel-meta/configs/Scribe.cfg
Requested value:  CONFIG_SND_SOC_MAX9768=y
Actual value:

Config 'SND_SOC_MAX9768' has the following conditionals:

Dependency values are:



SND_SOC_MAX9768 ends up not being selected even though I try to set it ti 'y'


The second one is CONFIG_MAX1363, this is an ADC that I'm trying to set, the warning is:

---------- CONFIG_MAX1363 -----------------
Config: CONFIG_MAX1363
From: /home/gwilson/Qt-5.9/Yocto-build-RPi3/build-raspberrypi3/tmp/work-shared/raspberrypi3/kernel-source/.kernel-meta/configs/Scribe.cfg
Requested value:  CONFIG_MAX1363=y
Actual value:     # CONFIG_MAX1363 is not set

Config 'MAX1363' has the following conditionals:
  I2C (value: "y")
Dependency values are:
  I2C [y]

It ends up being not set. In both cases the value that I'm trying to set is ignored. Any insight would be greatly appreciated.

Greg
