* rtc: remove useless DRV_VERSIONAlexandre Belloni2016-05-201-5/+0
| | | | | | | | | 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.

* rtc: ds1672, max6900, max8998: Add MODULE_DEVICE_TABLEAxel Lin2015-06-251-0/+1
| | | | | | | | | | | | | | | | | | 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>

* drivers/rtc/rtc-max6900.c: remove empty functionSachin Kamat2013-07-031-6/+0
| | | | | | | | | | | After the switch to devm_* functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it.

| | | | | | | | | | | | We now read and write the century byte in the max6900 chip. We probably don't need to do so on Linux-only system, but it's necessary when the chip is shared by another OS that uses the century byte.
