The DS3231 module is an inexpensive, high-accuracy, battery-backed RTC that sits on an I2C bus. This is an easy way to add persistent, network-independent time to devices such as the GL AR-750.

Support is provided by the ds1307 kernel module, and underlying I2C drivers.

Package kernel driver for DS3231 RTC
53bc54b 
Enable building and packaging the rtc-ds1307 kernel driver, which supports the high accuracy DS3231 RTC over I2C, along with other models. This can enable standalone real-time for devices with an exposed I2C bus, such as the GL-AR750.

This change cascades some additional kernel options around RTC and I2c support, and additionally builds the i2c-dev module, in the i2c-core package. The built-in changes increase the kernel.bin size by 17-18 kB.

Implements aredn#152
