I'm trying to add a couple of drivers to the kernel in a Raspberry pi3 build.
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: WARNING: linux-raspberrypi-1_4.4.50+gitAUTOINC+04c8e47067-r0 do_kernel_configcheck: [kernel config]: specified values did not make it into the kernel's final configuration: ---------- CONFIG_SND_SOC_MAX9768 ----------------- Config: CONFIG_SND_SOC_MAX9768 From: /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_SND_SOC_MAX9768=y Actual value: Config 'SND_SOC_MAX9768' has the following conditionals: Dependency values are: ---------- CONFIG_MAX1363 ----------------- Config: CONFIG_MAX1363 From: /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.
