It is similar to PMIC5-Gen2, with SW communication to ADCs on all PMICs going through PBS(Programmable Boot Sequence) firmware through a single register interface. This interface is implemented on an SDAM (Shared Direct Access Memory) peripheral on the master PMIC PMK8550 rather than a dedicated ADC peripheral. Add documentation for PMIC5 Gen3 ADC and macro definitions for ADC channels and virtual channels (combination of ADC channel number and PMIC SID number) per PMIC, to be used by clients of this device. Co-developed-by: Anjelique Melendez Signed-off-by: Anjelique Melendez Signed-off-by: Jishnu Prakash --- Changes since v3: - Added ADC5 Gen3 documentation changes in existing qcom,spmi-vadc.yaml file instead of adding separate file and updated top-level constraints in documentation file based on discussion with reviewers. - Dropped default SID definitions. - Addressed other reviewer comments. Changes since v2: - Moved ADC5 Gen3 documentation into a separate new file. Changes since v1: - Updated properties separately for all compatibles to clarify usage of new properties and updates in usage of old properties for ADC5 Gen3. - Avoided updating 'adc7' name to 'adc5 gen2' and just left a comment mentioning this convention. - Used predefined channel IDs in individual PMIC channel definitions instead of numeric IDs. - Addressed other comments from reviewers. .../bindings/iio/adc/qcom,spmi-vadc.yaml | 220 ++++++++++++++++-- .../iio/adc/qcom,spmi-adc5-gen3-pm8550.h | 46 ++++ .../iio/adc/qcom,spmi-adc5-gen3-pm8550b.h | 85 +++++++ .../iio/adc/qcom,spmi-adc5-gen3-pm8550vx.h | 22 ++ .../iio/adc/qcom,spmi-adc5-gen3-pmk8550.h | 52 +++++ include/dt-bindings/iio/adc/qcom,spmi-vadc.h | 81 +++++++ 6 files changed, 486 insertions(+), 20 deletions(-) create mode 100644 include/dt-bindings/iio/adc/qcom,spmi-adc5-gen3-pm8550.h create mode 100644 include/dt-bindings/iio/adc/qcom,spmi-adc5-gen3-pm8550b.h create mode 100644 include/dt-bindings/iio/adc/qcom,spmi-adc5-gen3-pm8550vx.h create mode 100644 include/dt-bindings/iio/adc/qcom,spmi-adc5-gen3-pmk8550.h diff --git a/Documentation/devicetree/bindings/iio/adc/qcom,spmi-vadc.yaml b/Documentation/devicetree/bindings/iio/adc/qcom,spmi-vadc.yaml index a4f72c0c1ec6..e6e1795af886 100644 --- a/Documentation/devicetree/bindings/iio/adc/qcom,spmi-vadc.yaml +++ b/Documentation/devicetree/bindings/iio/adc/qcom,spmi-vadc.yaml @@ -13,8 +13,12 @@ maintainers: description: | SPMI PMIC voltage ADC (VADC) provides interface to clients to read voltage.
