rtc: remove rtc-at32ap700x

2018-01-19T08:59:32Z

Since PLATFORM_AT32AP is an AVR32 platform which was removed, the rtc driver rtc-at32ap700x is useless. This patch remove it. Signed-off-by: Corentin Labbe Acked-by: Hans-Christian Noren Egtvedt Signed-off-by: Alexandre Belloni

rtc: add mxc driver for i.MX53 SRTC

2018-01-11T23:20:39Z

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53. This is driver enables support for the low power domain SRTC features: - 32-bit MSB of non-rollover time counter - 32-bit alarm register Select the new config option RTC_DRV_MXC_V2 to build this driver Based on: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01 Signed-off-by: Patrick Bruenn Acked-by: Philippe Ombredanne Signed-off-by: Alexandre Belloni

rtc: ds1307: add basic support for ds1341 chip

2017-08-31T23:10:18Z

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.
