2015-08-07Input: elants_i2c - wire up regulator supportDmitry Torokhov
Elan touchscreen controllers use two power supplies, vcc33 and vccio, and we need to enable them before trying to access the device. On X86 firmware usually does this, but on ARM it is usually left to the kernel.

2014-12-07Input: add support for Elan eKTH I2C touchscreensScott Liu
This driver supports Elan eKTH I2C touchscreen controllers. Note that these are using custom protocol, as opposed to other Elan parts that use HID-over-I2C and are supported by the standard HID-multitouch driver.
