2017-03-09rtc: rtc-ds1672: Add OF device ID tableJavier Martinez Canillas
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.

2016-05-20rtc: remove useless DRV_VERSIONAlexandre Belloni
Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found.

2015-06-25rtc: ds1672, max6900, max8998: Add MODULE_DEVICE_TABLEAxel Lin
The device table is required to load modules based on modaliases. After adding MODULE_DEVICE_TABLE, below entries will be added to modules.alias: alias i2c:ds1672 rtc_ds1672 alias i2c:max6900 rtc_max6900 alias platform:lp3974-rtc rtc_max8998 alias platform:max8998-rtc rtc_max8998 Signed-off-by: Axel Lin <axel.lin@gmail.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Dale Farnsworth <dale@farnsworth.org> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

2006-12-10[PATCH] RTCs don't use i2c_adapter.devDavid Brownell
Update more I2C drivers that live outside drivers/i2c to understand that using adapter->dev is not The Way. When actually referring to the adapter hardware, adapter->class_dev.dev is the answer. When referring to a device connected to it, client->dev.dev is the answer.
