Subject: [PATCH v3 0/3] Add the Renesas X9250 potentiometers IIO support

Hi,

The Renesas X9250 integrated four digitally controlled potentiometers.
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/20230420161052.270366-1-herve.codina@bootlin.com/
This v3 series updates the binding.

Best regards,
Herve Codina
