[PATCHv3 0/8] Add support for STM32 RTC

From: Amelie Delaunay
Date: Thu Jan 05 2017 - 08:46:37 EST


v3:
- rework set_alarm
- return platform_get_irq error code instead of -ENOENT

v2:
- remove clock-names and interrupt-names from bindings
- remove unuseful headers
- clean stm32_rtc structure
- replace stm32_rtc_readl/_writel by readl/writel_relaxed
- use threaded IRQ
- rework set_alarm
- add various comments
- select COMPILE_TEST and REGMAP_MMIO

This patchset adds support for the STM32 Real-Time Clock.
This RTC is an independent BCD timer/counter and provides a time-of-day
clock/calendar with programmable alarm interrupt.
RTC calendar can be driven by three clock sources LSE, LSI or HSE.

Amelie Delaunay (8):
