2018-05-18rtc: ls1x: add rangeAlexandre Belloni1-0/+2
While the year is encoded on 32 bits in SYS_TOYWRITE1i/SYS_TOYREAD1. The Loongson 1c datasheet states that the range is from 0 to 99. The current code exceeds this range and seems to be working, I deduce that the leap year algorithm will fail in 2100. Anyway, alarm registers only encode the year on 14 bits so with alarm support, the range will always be limited to 0 to 16383. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-17rtc: ls1x: remove useless label and gotoAlexandre Belloni1-8/+3
The error handling in ls1x_rtc_probe used to release resources but since it is using devm functions, it only returns a value. Make the code clearer by returning directly instead of using goto. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2018-05-03rtc: ls1x: remove mktime usageArnd Bergmann1-3/+4
The loongson1 platform is 32-bit, so storing a time value in 32 bits suffers from limited range. In this case it is likely to be correct until 2106, but it's better to avoid the limitation and just use the time64_t based mktime64() and rtc_time64_to_tm() interfaces. The hardware uses a 32-bit year number, and time64_t can cover that entire range. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-03-01rtc: stop validating rtc_time after rtc_time_to_tmAlexandre Belloni1-1/+1
rtc_time_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2017-01-11rtc: constify rtc_class_ops structuresBhumika Goyal1-1/+1
Declare rtc_class_ops structures as const as they are only passed as an argument to the function devm_rtc_device_register. This argument is of type const struct rtc_class_ops *, so rtc_class_ops structures having this property can be declared const.

2015-06-21MIPS: Loongson: Naming style cleanup and reworkHuacai Chen1-1/+1
Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

2013-07-03rtc: rtc-ls1x: 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-Hartman1-3/+3
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.
