I have discovered that the current version of rtc-x1205.c does not work correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl() call. This happens because the alarm registers do not behave like the current-time registers. They are non-volatile. Two things go wrong: - the X1205 requires a 10 msec delay after any attempt to write to the non-volatile registers. The x1205_set_datetime() routine does the write as 8 single-byte writes without any delay. Only the first write succeeds. The second is NAKed because the chip is busy. - the X1205 resets the RWEL bit after any write to the non-volatile registers. This would lock out any further writes after the first even with a 10msec delay. I fix this by doing a single 8-byte write and then waiting 10msec for the chip to be ready. A side effect of this change is that it will speed up x1205_rtc_set_time() which uses the same code. I have also implemented the 'enable' bit in the rtc_wkalm structure, which the existing driver does not attempt to do. I have modified both x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to return it. I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the alarm time matches the current time.

Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported.

The x1205 driver moved to the RTC subsystem and was significantly modified since then, so just delete the outdated documentation. Signed-off-by: NJean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <alessandro.zummo@towertech.it>

Stop using i2c_adapter.class_dev, as it is going to be removed soon. Luckily, there are only 4 RTC drivers affected. Signed-off-by: NJean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <a.zummo@towertech.it>

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.

A port of the existing x1205 driver under the new RTC subsystem. It is actually under test within the NSLU2 project (http://www.nslu2-linux.org) and it is working quite well. It is the first driver under this new subsystem and should be used as a guide to port other drivers.
