* i2c: Stop using i2c_adapter.class_devJean Delvare2007-02-13
| | | | | | | | 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: Jean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <a.zummo@towertech.it>
* [PATCH] Update the rtc-rs5c372 driverDavid Brownell2007-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugfixes: - Handle RTCs which are configured to use 12-hour mode. - Never report bogus/un-initialized times. - Displaying "raw trim" requires not masking it first! - Fix the sysfs and procfs display of crystal and trim data. Features: - Handle other RTCs in this family, notably rv5c386/rv5c387. - Declare the other registers. - Provide alarm get/set functionality. - Handle AIE and UIE; but no IRQ handling yet. Cleanup: - Shrink object by not including needless sysfs or procfs support - We don't need no steenkin' forward declarations. (Except one.) Until the I2C framework merges "new style" driver support, matching the driver model better, using rv5c chips or alarm IRQs requires a separate board-specific patch. (And an IRQ handler, handing off labor through a work_struct...) This uses the "method 3" register reads, but notes that it's done to work around an evident i2c adapter driver bug.

* [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.

* [PATCH] rtc-rs5c372: change register reading methodRiku Voipio2006-12-07
| | | | | | | | | | | According to the datasheet rs5c372 supports three different methods for reading register values. Change from method #1 to method #3, since method #3 is the only one that works on Thecus N2100 board with this RTC.

* [PATCH] drivers/rtc/rtc-rs5c372.c: fix a NULL dereferenceAdrian Bunk2006-11-25
| | | | | | | | | | | | | | The correct order is: NULL check before dereference This was a guaranteed NULL dereference with debugging enabled since rs5c372_sysfs_show_osc() does actually pass NULL... Spotted by the Coverity checker.

* [PATCH] constify rtc_class_ops: update driversDavid Brownell2006-10-01
