This device is at the messy boundary between IIO and HWMON. Perhaps call out the reasons you think IIO is more appropriate in this cover letter. + Often a good idea for these borderline parts to cc both mailing lists and maintainers. Often the conclusion is that it is fine to have these in IIO because we can bridge to hwmon anyway with the iio-hwmon driver. > > Differences related to previous patch: > > v1: > - first version comitted to review > > > Marius Cristea (2): > dt-bindings: iio: adc: adding dt-bindings for PAC193X > iio: adc: adding support for pac193x > > .../bindings/iio/adc/microchip,pac193x.yaml | 122 + > MAINTAINERS | 7 + > drivers/iio/adc/Kconfig | 12 + > drivers/iio/adc/Makefile | 1 + > drivers/iio/adc/pac193x.c | 2072 +++++++++++++++++ > 5 files changed, 2214 insertions(+) > create mode 100644 Documentation/devicetree/bindings/iio/adc/microchip,pac193x.yaml > create mode 100644 drivers/iio/adc/pac193x.c >

I was thinking to start with a simple driver (this one that is more apropiate to be a HWMON) and add more functionality later (like data buffering that is quite important for example if someone wants to profile power consumtion of the procesor itself, or a pheriperic, or a battery) > > > > Differences related to previous patch: > > > > v1: > > - first version comitted to review > > > > > > Marius Cristea (2): > > dt-bindings: iio: adc: adding dt-bindings for PAC193X > > iio: adc: adding support for pac193x > > > > .../bindings/iio/adc/microchip,pac193x.yaml | 122 + > > MAINTAINERS | 7 + > > drivers/iio/adc/Kconfig | 12 + > > drivers/iio/adc/Makefile | 1 + > > drivers/iio/adc/pac193x.c | 2072 > > +++++++++++++++++ > > 5 files changed, 2214 insertions(+) > > create mode 100644 > > Documentation/devicetree/bindings/iio/adc/microchip,pac193x.yaml > > create mode 100644 drivers/iio/adc/pac193x.c > > > Thanks, Marius

List out some of the things you want to do later as the reasoning +CC hmwon maintainers just to be sure. They are usually fine with this sort of reasoning, but it is best to check anyway.
