[PATCH 02/13] rtc: rv3029: Add OF device ID table

From: Javier Martinez Canillas
Date: Fri Mar 03 2017 - 09:32:30 EST


The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
