* drivers/rtc/: use bcd2bin/bin2bcdAdrian Bunk2008-10-20
| | | | | | | | | | | Change drivers/rtc/ to use the new bcd2bin/bin2bcd functions instead of the obsolete BCD_TO_BIN/BIN_TO_BCD/BCD2BIN/BIN2BCD macros.

* rtc-pcf8563: remove client validationLaurent Pinchart2008-10-16
| | | | | | | | | | | | 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.

* i2c: Convert most new-style drivers to use module aliasingJean Delvare2008-04-29
| | | | | | | | | | | | | | 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.

* i2c: Add support for device alias namesJean Delvare2008-04-29
| | | | | | | | | | | | | | 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.

* [PATCH] rtc-pcf8563: detect polarity of century bit automaticallyAtsushi Nemoto2007-02-09
| | | | | | | | | | | | | | | | | 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.

* [PATCH] RTCs don't use i2c_adapter.devDavid Brownell2006-12-10
| | | | | | | | | | | | 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.

| | | | | | | | | | | 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.
