I agree with Arnd's point here. It makes sense to me to have this driver under the IIO umbrella. > On the driver side, I believe the correct way to deal with this setup > is to split your driver into a generic drivers/iio/adc/rockchips-tsadc.c > file, and a smaller thermal driver that uses the iio in-kernel interfaces, > ideally one that is independent of the underlying hardware and can > work on any ADC implementation. > Agreed. If you can write such interface and make your driver to work in such way, that would be great. > I've put the IIO maintainer on Cc in this mail, maybe Jonathan or someone > else on the linux-iio mailing list has some extra insight. > > Arnd Cheers, Eduardo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
