Subject: [PATCH 00/11] iio: adc: Add support for QCOM SPMI PMIC5 Gen3 ADC
Date:   Sat, 8 Jul 2023 12:58:24 +0530

PMIC5 Gen3 has a similar ADC architecture to that on PMIC5 Gen2,
with all SW communication to ADC going through PMK8550 which
communicates with other PMICs through PBS. 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.

Patches 1-5 update the name of the previous generation of PMIC5 ADC peripherals
from ADC7 to ADC5 Gen2, as this is the correct name and it makes more sense now
to update it, with the addition of the latest ADC5 Gen3 peripheral support.

Patches 6 and 7 add bindings and driver support respectively for ADC5 Gen3.

Patches 8-11 are for an additional change, where the QCOM ADC dt-bindings files
are moved from dt-bindings/iio to dt-bindings/iio/adc folder, as they are
specifically for ADC devices.
