2017-09-01rtc: ds1307: add basic support for ds1341 chipNikita Yushchenko1-5/+5
This adds support for reading and writing date/time from/to ds1341 chip. ds1341 chip has other features - alarms, input clock (can be used instead of intercal oscillator for better accuracy), output clock ("square wave generation"). However, not all of that is available at the same time. Same chip pins, CLKIN/nINTA and SQW/nINTB, can be used either for input/output clocks, or for alarm interrupts. Role of these pins on particular board depends on hardware wiring. We can add device tree properties that describe if each of pins is wired as clock, or as interrupt, or left unconnected, and enable support for corresponding functionality based on that. But that is cumbersome, requires hardware for testing, and has to deal with bit enabling/disabling output clock also affects which pins alarm interrupts are routed to. Another factor is that there are hardware setups (i.e. ZII RDU2) that power DS1341 from SuperCap, which makes power saving critical. For such setups, kernel driver should leave register bits that control mentioned pins in the state configured by bootloader. Given all that, it was decided to limit support to "only date/time" for now. That is enough for common use case. Full (and cumbersome) implementation can be added later if ever needed.

2017-07-07rtc: add generic nvmem supportAlexandre Belloni1-0/+8
Many RTCs have an on board non volatile storage. It can be battery backed RAM or an EEPROM. Use the nvmem subsystem to export it to both userspace and in-kernel consumers. This stays compatible with the previous (non documented) ABI that was using /sys/class/rtc/rtcx/device/nvram to export that memory. But will warn about the deprecation.

2016-08-08rtc: ac100: Add RTC driver for X-Powers AC100Chen-Yu Tsai1-0/+10
X-Powers AC100 is a codec / RTC combo chip. This driver supports the RTC sub-device. The RTC block also has clock outputs and non-volatile storage. Non-volatile storage wthin the RTC hardware is not supported. Clock output support is added in the next patch.

2016-06-26rtc: move mc146818 helper functions out-of-lineArnd Bergmann1-0/+6
The mc146818_get_time/mc146818_set_time functions are rather large inline functions in a global header file and are used in several drivers and in x86 specific code. Here we move them into a separate .c file that is compiled whenever any of the users require it. This also lets us remove the linux/acpi.h header inclusion from mc146818rtc.h, which in turn avoids some warnings about duplicate definition of the TRUE/FALSE macros.
