Dear Andrew Lunn,

This is not actually true. Its dependent on at least one external

There are a few Kirkwood and XP designs which use an external i2c RTC,
because the battery recommended by Marvell is mechanically not so easy
to attached to the board, in a robust way.
So i expect some boards will disable this from there own .dts file.
However, defaulting to enabled would make sense.
Ok, thanks for the clarification!
Indeed, the OpenBlocks for example has a RTC on I2C, so maybe it'll
want to disable the on-SoC RTC.
Best regards,
Thomas
