[PATCH v2 0/4] Add Ayn EC Platform Driver

["Derek J. Clark" <derekjohn.clark@gmail.com>]

Adds platform driver for Ayn Loki and Tactoy Zeenix handheld devices.
Tactoy devices are rebranded Ayn devices with minor modifications to the
DMI. The device EC has multiple features implemented by this driver,
including a PWN fan with manual and EC controlled automatic modes as
well as a user deviced fan curve mode, temperature sensors, and chassis
RGB control.

This driver implements PWN fan and temperature control via a hwmon
interface, and an RGB chassis interface via a multicolor LED class
device. I attempted to break the driver up into four logical patches.
Patch 1 adds PWM fan control via a hwmon interface. Patch 2 expands the
hwmon interface by adding the temperature sensors. Patch 3 adds the
chassis RGB interface through the leds subsystem. Patch 4 adds ABI
documentation for the sysfs entries that aren't provided by the standard
interfaces, but are needed to fully control the device.
