For I2C two other configs should be also auto-selected: +CONFIG_I2C=y +CONFIG_I2C_ALGOBIT=y +CONFIG_I2C_BOARDINFO=y +CONFIG_I2C_GPIO=y And in case of CONFIG_SPI_GPIO, it's already selected in top-level target config: https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/config-4.19#L216 https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/config-4.14#L223 'make kernel_menuconfig CONFIG_TARGET=subtarget' will solve that. > Signed-off-by: Daniel Golle <daniel@makrotopia.org> Acked-by: Piotr Dymacz <pepe2k@gmail.com>

For devices having LEDs or buttons connected via I2C or SPI connected GPIO chips it is desireable to access these busses early during boot in order to signal progress and failsafe-mode. Hence have support for i2c-gpio and spi-gpio built-into the kernel on generic (ie. non-tiny) systems.
