In the variant RC5T619 the mfd has an RTC. This patchset adds support for it. To do so it adds the missing register defines in rn5t618.h and general irq handling for that. It seems that the irq definitions are the same except missing RTC but due to missing ability to test that I do not add them here. 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. For cleaning up there is a separate off-topic patch: mfd: rn5t618: cleanup i2c_device_id Changes in v5: - static rn5t618_irq_init - PLATFORM_DEVID_NONE - added some Acked-Bys Changes in v4: - use macros for IRQ definitions - merge rn5t618-core.c and rn5t618-irq.c 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 (5): dt-bindings: mfd: rn5t618: Document optional property interrupts mfd: rn5t618: add IRQ support mfd: rn5t618: add RTC related registers mfd: rn5t618: add more subdevices rtc: rc5t619: add ricoh rc5t619 RTC driver Documentation/devicetree/bindings/mfd/rn5t618.txt | 4 + drivers/mfd/Kconfig | 1 + drivers/mfd/rn5t618.c | 109 +++++- drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-rc5t619.c | 444 ++++++++++++++++++++++ include/linux/mfd/rn5t618.h | 26 ++ 7 files changed, 593 insertions(+), 2 deletions(-) create mode 100644 drivers/rtc/rtc-rc5t619.c -- 2.11.0
