I still use the original AS73211, so I can offer testing with it. I am currently away, I'll do the tests on 2023-12-30 and report the result then. > > Signed-off-by: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx> > --- > Javier Carrasco (2): > dt-bindings: iio: light: as73211: add support for as7331 > io: light: as73211: add support for as7331 > > .../devicetree/bindings/iio/light/ams,as73211.yaml | 7 +- > drivers/iio/light/Kconfig | 5 +- > drivers/iio/light/as73211.c | 146 > +++++++++++++++++---- 3 files changed, 127 insertions(+), 31 deletions(-) > --- > base-commit: e9215fcca2561b208c78359110ee4009b454f761 > change-id: 20231220-as7331-88a25ceeb66d > > Best regards,
