2018-03-02rtc: stop validating rtc_time in .read_timeAlexandre Belloni1-2/+1
The RTC core is always calling rtc_valid_tm after the read_time callback. It is not necessary to call it just before returning from the callback. Signed-off-by: Alexandre Belloni <[email protected]>
2018-02-13rtc: ds1302: remove redundant initializations of pointer bpColin Ian King1-2/+2
Pointe bp is being initialized and this value is never read, it is being updated to the same value later just before it is going to be used. Remove the initialization as it is never read and keep the setting of bp closer to the use of bp.

2016-09-02rtc: constify rtc_class_ops structuresJulia Lawall1-1/+1
Check for rtc_class_ops structures that are only passed to devm_rtc_device_register, rtc_device_register, platform_device_register_data, all of which declare the corresponding parameter as const. Declare rtc_class_ops structures that have these properties as const.

2016-05-20rtc: ds1302: fix write value for day of week registerAkinobu Mita1-1/+1
The valid range of day of week register for DS1302 is 1 to 7. But the set_time callback for rtc-ds1302 attempts to write the value of tm->tm_wday which is in the range 0 to 6. While the get_time callback correctly decodes the register.

2016-05-20rtc: ds1302: fix error check in set_timeAkinobu Mita1-1/+1
The set_time callback for rtc-ds1302 doesn't write clock registers because the error check for the return value from spi_write_then_read() is not correct. spi_write_then_read() which returns zero on success.

2016-05-20rtc: remove useless DRV_VERSIONAlexandre Belloni1-2/+0
Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found. Signed-off-by: Alexandre Belloni <[email protected]>
2016-05-20rtc: ds1302: rewrite using SPISergey Yanovich1-191/+157

2013-07-03rtc: rtc-ds1302: remove unnecessary platform_set_drvdata()Jingoo Han1-2/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.

2013-01-03Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2010-10-29sh: mach-snapgear: Kill off machtype, consolidate board def.Paul Mundt1-1/+1
Only the secureedge5410 was ever supported by this code, so make the board specification explicit rather than perpetuating a mach group. Signed-off-by: Paul Mundt <[email protected]>
2010-05-25rtc-ds1302: add some abstraction for new platform supportMarc Zyngier1-18/+67
The current ds1302 driver (or at least the one that lives in /drivers/rtc) seems to be designed for memory mapped devices only. This make it quite hard to add support for GPIO-based implementations (as this is the case for the upcoming Arcom Vulcan). This patch moves the direct register access to inline functions with explicit names. Still not as good as a proper platform driver, but at least neater.

2008-02-06rtc: ds1302 rtc supportPaul Mundt1-0/+262
This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.
