2009-12-16rtc: fix driver data issues in several rtc driversAlessandro Zummo
Herton Ronaldo Krzesinski recently raised up, and fixed, an issue with the rtc_cmos driver, which was referring to an inconsistent driver data. This patch ensures that driver data registration happens before rtc_device_register().

2008-10-16rtc-pcf8563: remove client validationLaurent Pinchart
Validating clients with black magic register checks doesn't make much sense for new-style i2c driver and has been known to fail on valid NXP pcf8563 chips. This patch removes the client validation code.

2008-04-29i2c: Convert most new-style drivers to use module aliasingJean Delvare
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.

2008-04-29i2c: Add support for device alias namesJean Delvare
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.

2007-02-09[PATCH] rtc-pcf8563: detect polarity of century bit automaticallyAtsushi Nemoto
The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

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.

2006-10-01[PATCH] rtc driver rtc-pcf8563 century bit inversedJean-Baptiste Maneyrol
The century bit PCF8563_MO_C in the month register is misinterpreted. It is set to 1 for the 20th century and 0 for 21th, and the driver is expecting the opposite behavior.
