This series introduces STM32MP1 RTC. On STM32MP1: - two clocks are needed, plck and rtc_ck; - to wakeup the system, a wakeup alarm interrupt is needed; - some registers or bits have moved, but the operation is the same; - the Backup Domain Protection (DBP) is not managed by RTC driver. --- Changes in v3: * Move cleanup changes in a separate patch * Replace regs and evts by pointers to ensure no copy is made * Set all registers offset as u16 instead of u8 and u16 * Fix Kbuild smatch warning: drivers/rtc/rtc-stm32.c:827 stm32_rtc_probe() warn: always true condition '(regs.verr != ~0) => (0-u16max != (-1))' Changes in v2: * One compatible per line in bindings file * Remove unnecessary comment under rtc_ck as this clock is required for all * Remove interrupts-extended and add stm32mp1 rtc alarm wakeup interrupt in interrupts property description Amelie Delaunay (4): rtc: stm32: fix misspelling and misalignment issues rtc: stm32: rework register management to prepare other version of RTC dt-bindings: rtc: update stm32-rtc documentation for stm32mp1 rtc rtc: stm32: add stm32mp1 rtc support .../devicetree/bindings/rtc/st,stm32-rtc.txt | 27 +- drivers/rtc/rtc-stm32.c | 273 ++++++++++++++++----- 2 files changed, 229 insertions(+), 71 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
