This patchset adds support for it. To do so it adds the missing register defines in rn5t618.h and general irq handling for that. Probably the irq definitions are the same except missing rtc + charger but due to missing information about that I do not add them. There might be some oddity about the charger irq which should be researched when adding the charger subdevice. The rtc driver itself is based on https://github.com/kobolabs/Kobo-Reader/blob/master/hw/imx6sll-clara/kernel.tar.bz2 but heavily reworked. It was tested on the Kobo Clara HD. Changes in v3: - alignment cleanup - output cleanup, remove useless toggling of alarm flag in rtc probe - updated bindings description, so patch 1/5 becomes 2/6 and so on Changes in v2: - no dead code in irq code - various improvements and cleanups in rtc driver itself Andreas Kemnade (6): dt-bindings: mfd: rn5t618: Document optional property interrupts mfd: rn5t618: prepare for irq handling mfd: rn5t618: add irq support mfd: rn5t618: add rtc related registers mfd: rn5t618: add more subdevices rtc: rtc-rc5t619: add ricoh rc5t619 RTC driver .../devicetree/bindings/mfd/rn5t618.txt | 3 + drivers/mfd/Kconfig | 1 + drivers/mfd/Makefile | 2 + drivers/mfd/{rn5t618.c => rn5t618-core.c} | 52 +- drivers/mfd/rn5t618-irq.c | 85 ++++ drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-rc5t619.c | 462 ++++++++++++++++++ include/linux/mfd/rn5t618.h | 27 + 9 files changed, 640 insertions(+), 3 deletions(-) rename drivers/mfd/{rn5t618.c => rn5t618-core.c} (78%) create mode 100644 drivers/mfd/rn5t618-irq.c create mode 100644 drivers/rtc/rtc-rc5t619.c
