From ffbecfbdbeeebe9749398fe9eb9eab2dd47ddff4 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 3 Mar 2017 11:29:22 -0300 Subject: [PATCH] rtc: rx8581: Add OF device ID table 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:. 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.
