Hello, This series add support for adaq4370-4 (2MSPS) and adaq4380-4 (4MSPS) which are quad-channel precision data acquisition signal chain μModule solutions compatible with the ad738x family, with the following differences: - pin selectable gain in front of each 4 adc - internal reference is 3V derived from refin-supply (5V) - additional supplies This series depends on [1] which fix several supplies issues [1]: https://lore.kernel.org/all/20241007-ad7380-fix-supplies-v1-0-badcf813c9b9@xxxxxxxxxxxx/ Signed-off-by: Julien Stephan <jstephan@xxxxxxxxxxxx> --- Changes in v4: - Adding a new patch to pull out a local "dev" variable to shorten some long lines - Fix few minor comment from Jonathan Cameron and David Lechner - Link to v3: https://lore.kernel.org/r/20241024-ad7380-add-adaq4380-4-support-v3-0-6a29bd0f79da@xxxxxxxxxxxx Changes in v3: bindings: - remove item from channel reg property (should be part of V2, but get lost during rebase) - remove unnecessary () for channel property - keep consistent quotes - Link to v2: https://lore.kernel.org/r/20241023-ad7380-add-adaq4380-4-support-v2-0-d55faea3bedf@xxxxxxxxxxxx Changes in v2: - fix commit messages and documentation about the gain: pin selectable gain instead of configurable gain - add the enum of available gains inthe binding and array of available gains in the driver as ad4000 series - in the bindings, remove item from channel reg property - in the bindings, merge additional supplies and channel properties inside the same if branch for adaq devices - fix comment as suggested by Jonathan in the driver - Link to v1: https://lore.kernel.org/r/20241015-ad7380-add-adaq4380-4-support-v1-0-d2e1a95fb248@xxxxxxxxxxxx --- Julien Stephan (5): dt-bindings: iio: adc: ad7380: add adaq4370-4 and adaq4380-4 compatible parts iio: adc: ad7380: fix oversampling formula iio: adc: ad7380: use local dev variable to shorten long lines iio: adc: ad7380: add support for adaq4370-4 and adaq4380-4 docs: iio: ad7380: add adaq4370-4 and adaq4380-4 .../devicetree/bindings/iio/adc/adi,ad7380.yaml | 120 ++++++++++++++ Documentation/iio/ad7380.rst | 16 ++ drivers/iio/adc/ad7380.c | 178 ++++++++++++++++++--- 3 files changed, 290 insertions(+), 24 deletions(-) --- base-commit: 8bea3878a1511bceadc2fbf284b00bcc5a2ef28d change-id: 20241015-ad7380-add-adaq4380-4-support-14dc17ec0029 prerequisite-change-id: 20241004-ad7380-fix-supplies-3677365cf8aa:v3 prerequisite-patch-id: 6127a52d3b14e82d1a6081c7e504d0e4eb323089 prerequisite-patch-id: 7dee57142d0d12682b0be3b62f1c16851aeac069 prerequisite-patch-id: f737e56a372cd91e5fac651a2063b06827f9aa21 prerequisite-patch-id: 7c8d5fbde82810057630b95e12bb2f6576da6980 prerequisite-patch-id: 972bdbf06bafa7c56f604dbe8eb7d236aadaad99 Best regards, -- Julien Stephan <jstephan@xxxxxxxxxxxx>
