Ok, boot ubuntu from USB stick, and everything works. I've sound (mic works too), touchscreen, and microSD all working. And I took the lsmod list from the Ubuntu USB boot-up, and went back my vanilla linux kernel, using the same .confg from ubuntu, recompiled the kernel, and loaded the same module names as ubuntu loaded in the USB boot up, and this time everything worked! Vanilla pure linux setup. Just latest Linux kernel from git, Alsa, and SOF (sof-bin-2023.12.tar.gz). The only firmware missng are cirrus/cs35l41-dsp1-spk-prot.bin and cirrus/cs35l41-dsp1-spk-prot.wmfw and I took those from Ubuntu USB boot up. Thank you all! I'll test further, and list which modules are needed for sound, touchscreen, and micro SD.
