It depends on the IRQ support added in the RTC support series here: https://lore.kernel.org/lkml/20191220122416.31881-1-andreas@kemnade.info/ First regmap setup has to be fixed because there is a register wrongly classified as volatile. 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 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.
