[PATCH 1/3] rtc: ds1307: Add ds1339 compatible
As far as u-boot is concerned the ds1339 is compatible with the other devices supported by the ds1307 driver. The Linux driver does expose some additional functionality but as far as u-boot is concerned just adding the compatible string is enough.

The T2080RDB has a ds1339 on i2c0. Add this to the devicetree and enable the relevant support in the configs.
