In case it is useful to know, I installed Debian stretch following this: https://wiki.debian.org/InstallingDebianOn/Asus/E200HA I built my kernel using a relatively minimal kernel config, let me know if you want it. I could also post the two patches which port the mfd and opregion drivers, but they are straight forward copies of intel_soc_pmic_crc.c and intel_pmic_crc.c from 4.10.0-rc6+ with code copy&pasted from the ProductionKernelQuilts patches and s/crc/dc_ti/ etc., except I scamped the thermal handler to skip the ADC driver port for now. Maybe I should've used intel_pmic_xpower.c instead of intel_pmic_crc.c, since as I write this I see there is a no-op intel_xpower_pmic_gpio_handler() registered. This is the trick that fixes this: \_SB.PCI0.I2C7.PMI2.AVBG Integer ffff8be7b74d9be0 01 = 0000000000000001 But now it generates ACPI errors about thermal zone and "acpi -V" usually hangs it up.
