The major difference is that the register interface used here is that of an SDAM present on PMK8550, rather than a dedicated ADC peripheral. There may be more than one SDAM used for ADC5 Gen3. Each ADC SDAM has eight channels, each of which may be used for either immediate reads (same functionality as previous PMIC5 and PMIC5 Gen2 ADC peripherals) or recurring measurements (same as PMIC5 and PMIC5 Gen2 ADC_TM functionality). In this case, we have VADC and ADC_TM functionality combined into the same driver. Patch 1 is a cleanup, to move the QCOM ADC dt-bindings files from dt-bindings/iio to dt-bindings/iio/adc folder, as they are specifically for ADC devices. It also fixes all compilation errors with this change in driver and devicetree files and similar errors in documentation for dtbinding check. Patch 2 adds bindings for ADC5 Gen3 peripheral. Patch 3 adds driver support for ADC5 Gen3. Changes since v2: - Reordered patches to keep cleanup change for ADC files first. - Moved ADC5 Gen3 documentation into a separate file Changes since v1: - Dropped patches 1-5 for changing 'ADC7' peripheral name to 'ADC5 Gen2'. - Addressed reviewer comments for binding and driver patches for ADC5 Gen3. - Combined patches 8-11 into a single patch as requested by reviewers to make the change clearer and made all fixes required in same patch.
