[PATCH 2/2] regulator: ltc3676: Add OF device ID table

From: Javier Martinez Canillas
Date: Tue Feb 21 2017 - 09:29:41 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.
