SD Card Reader

Enable kernel config option CONFIG_MFD_RTSX_PCI (aka Device Drivers --> Multifunction device drivers --> Realtek PCI-E card reader).


Whoo boy. This one took a while to figure out. I knew that Linux had support for this touchscreen, because live CDs using all-inclusive kernel configurations supported it.

Turns out it’s an I2C touchscreen using the hid-multitouch driver running off of a “Sunrise Point-LP Serial IO I2C Controller”, according to lspci. I had enabled hid-multitouch and i2c_hid and everything, so why didn’t it work??

Turns out the I2C controller uses the kernel’s Intel Low Power Subsystem driver (LPSS), which I had disabled. It’s in Device drivers --> Multifunction device drivers. You then should enable the Quark config option that shows up, then go back to Device drivers --> I2C support --> I2C Hardware Bus support and you’ll see CONFIG_I2C_DESIGNWARE_PLATFORM and CONFIG_I2C_DESIGNWARE_BAYTRAIL show up. Enable those, and that should work. (I don’t know if all of those are necessary, but that’s what worked for me!)
