RTC on H6 is similar to the one on H5 SoC, but incompatible in small details. See the driver for description of differences. For example H6 RTC needs to enable the external low speed oscillator. Add new compatible for this RTC.

- the Low Frequency Oscillator or LOSC, at index 0,
|
|
- the Low Frequency Oscillator External output (X32KFOUT in
|
|
the datasheet), at index 1,
|
|
- the Internal Oscillator, at index 2.
