rtc: rv3029: Clean up error handling in rv3029_eeprom_write()

2017-10-12T14:24:19Z

We don't need both "ret" and "err" when they do the same thing. All the functions called here return zero on success or negative error codes. It's more clear to return a literal zero at the end instead of "return ret;" Signed-off-by: Dan Carpenter Signed-off-by: Alexandre Belloni

rtc: rv3029: fix vendor string

2017-09-26T13:34:41Z

The vendor string for Microcrystal is microcrystal. Acked-by: Rob Herring Signed-off-by: Alexandre Belloni

rtc: constify i2c_device_id

2017-08-31T23:10:11Z

i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by work with const i2c_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Alexandre Belloni

rtc: rv3029: Add OF device ID table

2017-03-09T00:29:16Z

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

rtc: rv3029: hide unused i2c device table

2016-05-21T15:07:16Z

The added support for SPI mode made it possible to configure the driver when I2C is disabled, leaving an unused device table: drivers/rtc/rtc-rv3029c2.c:794:29: error: 'rv3029_id' defined but not used [-Werror=unused-variable] This moves the table inside of the #ifdef section that has the only user, to avoid the harmless warning.

rtc: rv3029: add alarm IRQ

Add the alarm IRQ functionality. Signed-off-by: Mylène Josserand Signed-off-by: Alexandre Belloni

rtc: rv3029: fix set_time function

2016-05-21T15:06:58Z

The bin2bcd function in set_time is uncorrect on weekdays as the bit mask should be done at the end of arithmetic operations. Signed-off-by: Mylène Josserand Signed-off-by: Alexandre Belloni

rtc: rv3029: fix alarm support

2016-05-21T15:06:56Z

The RTC RV3029 handles different types of alarms : seconds, minutes, ... These alarms can be enabled or disabled individually using an AE_x bit which is the last bit (BIT(7)) on each alarm registers. To prepare the alarm IRQ support, the current code enables all the alarm types by setting each AE_x to 1. It also fixes others alarms issues : - month and weekday errors : it was performing -1 instead of +1. - wrong use of bit mask with bin2bcd Signed-off-by: Mylène Josserand Signed-off-by: Alexandre Belloni

rtc: rv3029: Remove some checks and warnings

2016-05-21T15:06:54Z

Remove some checks from checkpatch such as spaces around arithmetic operations or prefer "unsigned int". Signed-off-by: Mylène Josserand Signed-off-by: Alexandre Belloni

rtc: rv3029: Add support of RV3049

2016-05-21T15:06:52Z

Add support of Microcrystal RV3049 RTC (SPI) using regmap on the RV3029 (I2C) driver. Signed-off-by: Mylène Josserand Signed-off-by: Alexandre Belloni
