When driver model is used for I2C, the real-time clock functionality does not work (e.g. the 'date' command gives build errors when CONFIG_DM_I2C is defined). It is possible to work around this by using driver model I2C functions. But what is really needed is an RTC uclass.
This series: - renames some RTC functions to have an rtc_ prefix - adds sandbox support for RTC and an emulated I2C RTC device - adds a driver model RTC uclass and associated tests - corrects various minor driver model I2C issues that were discovered With this it should be fairly easy to convert an existing RTC driver to driver model, but this series does not include that as I'm not sure if any of the boards I have include an RTC.
