On each potentiometer, the X9250T has a 100 kOhms total resistance and the X9250U has a 50 kOhms total resistance. Compare to the previous iteration https://lore.kernel.org/linux-kernel/20230420121320.252884-1-herve.codina@bootlin.com/ This v2 series uses a define for the X9250 ID value. Best regards, Herve Codina Changes v1 -> v2 - Patch 1 No changes - Patch 2 Use a define for the 0x50 value used multiple times. - Patch 3 No changes Herve Codina (3): dt-bindings: iio: potentiometer: Add the Renesas X9250 potentiometers iio: potentiometer: Add support for the Renesas X9250 potentiometers MAINTAINERS: add the Renesas X9250 driver entry .../iio/potentiometer/renesas,x9250.yaml | 56 +++++ MAINTAINERS | 7 + drivers/iio/potentiometer/Kconfig | 10 + drivers/iio/potentiometer/Makefile | 1 + drivers/iio/potentiometer/x9250.c | 234 ++++++++++++++++++ 5 files changed, 308 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/potentiometer/renesas,x9250.yaml create mode 100644 drivers/iio/potentiometer/x9250.c
