It depends on the IRQ support added in the RTC support series here: https://lore.kernel.org/lkml/20191220122416.31881-1-andreas@kemnade.info/ I tested the driver only with the RC5T619 but it should work with the with the RN5T618 as well based on these facts: - The corresponding register definitions originally went into the kernel for the RN5T618 - Public datasheet sections about the ADC look same. - Out-of-tree code for these chips look same regarding to ADC But due to missing hardware I cannot test the patches 2/3 and 3/3 which add support for the RN5T618 ADC. I marked these untested patches as RFC, and IMHO they require a Tested-By. Feel free to ignore them if the whole series would be delayed just because of missing Tested-By for those. Changes in v3: - re-included former 2/5 of these patches, since it was not applied Changes in v2: - got an "Applied, thanks" message for the first two, so I do not include them anymore - some cleanups for the ADC driver itself Andreas Kemnade (4): mfd: rn5t618: add ADC subdevice for RC5T619 iio: adc: rn5t618: Add ADC driver for RN5T618/RC5T619 mfd: rn5t618: add IRQ definitions for RN5T618 mfd: rn5t618: add ADC subdevice for RN5T618 drivers/iio/adc/Kconfig | 10 ++ drivers/iio/adc/Makefile | 1 + drivers/iio/adc/rn5t618-adc.c | 258 ++++++++++++++++++++++++++++++++++ drivers/mfd/rn5t618.c | 48 ++++++- 4 files changed, 315 insertions(+), 2 deletions(-) create mode 100644 drivers/iio/adc/rn5t618-adc.c
