Ch340 integration with SC696S YOCTO image

I need a guide or a patch to integrate the ch340 driver & FTDI USB serial driver with the SC696S YOCTO image. I see something on other communities using make menuconfig, i open make menuconfig & see ch340 driver inside USB Serial support but when I save & exit & try to build the image again I get an error while build-qti-robotics-med-image , i don’t know if I did with true way, so please help me.

You could modify the
src/kernel/msm-4.14/arch/arm64/configs/vendor/trinket-perf_debug and trinket_defconfig directly and add the kernel config.

CONFIG_USB_SERIAL_CH341=y
CONFIG_USB_SERIAL=y
