rtc: ds1307: add support for mcp7940x chips

2014-12-11T01:41:15Z

MCP7940x is same RTC as MCP7941x. The difference is that MCP7941x chips contain additional EEPROM on a different i2c address. DS1307 driver already supports MCP7941x, so just add a new i2c device id and rename functions and defines accordingly.

rtc: ds1307: add trickle charger device tree binding

2014-10-14T00:18:18Z

Some DS13XX devices have "trickle chargers". Introduce a device tree binding for specifying the trickle charger configuration for ds1339. Only ds1339 dt binding is supported because this is the only chip I have. I _assume_ the code would have worked on other allready supported chips. However I cannot check the resistor values for the other chips or test them. For other chips the driver code works as earlier Eg. it does not check the dt bindings at all Signed-off-by: Matti Vaittinen Cc: Rob Herring Cc: Pawel Moll Cc: Jason Cooper Cc: Guenter Roeck Cc: Alessandro Zummo Cc: Mark Rutland Cc: Pavel Machek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-ds1307.c: add alarm support for mcp7941x chips

2014-04-03T23:21:20Z

Add alarm support for the Microchip RTC devices MCP794xx. Note that two programmable alarms are provided by the chip but only one is used by the driver.

drivers/rtc/rtc-ds1307.c: fix sysfs wakealarm attribute creation

2014-04-03T23:21:20Z

In order to allow the creation of the sysfs attribute wakealarm, this patch moves the device_set_wakeup_capable() call above the RTC device registration.

drivers/rtc/rtc-ds1307.c: change variable type to bool

2013-11-13T03:09:30Z

The variable want_irq is only assigned the values true and false. Change its type to bool. The simplified semantic patch that find this problem is as follows (http://coccinelle.lip6.fr/): @exists@ type T; identifier b; @@ - T + bool b = ...; ... when any b = \(true\|false\) Signed-off-by: Peter Senna Tschudin Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-ds1307.c: use dev_get_platdata()

2013-11-13T03:09:29Z

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-ds1307.c: release irq on error

'client->irq' was not released on error. Fix it. Signed-off-by: Sachin Kamat Cc: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-ds1307: use devm_*() functions

drivers/rtc/rtc-ds1307.c: change sysfs function pointer assignment

2013-04-30T01:28:34Z

The current usage of commas instead of semicolons is not wrong, but affects the readability of the code. Also, the code would break, if someone puts something between those two assignments. Signed-off-by: Steffen Trumtrar Cc: Austin Boyle Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
