[PATCH RFC v2 0/6] arm64: dts: qcom: sm8[56]50: add PMIC5 Gen3 ADC channels

From: Neil Armstrong

Date: Mon May 04 2026 - 12:30:08 EST


Now the bindings and driver was merged for the SPMI PMIC5 Gen3 ADC
found on the PMK8550 which allow reading ADC data on the PMK8550
and other PMICs on the system.

First, add the PMIC5 Gen3 macros to calculate the channel numbers which
is a combination of SPMI bus number and a constant for the sensor
type and configuration.

The macros definitions were taken out of [1] where it was initially
in the dt-bindings include directory but since those are not hardware
bindings but logical numbers, they can be moved to local includes
instead to make the DT source more readable.

Finally add the SPMI ADC channels on the PMK8550 SPMI5 ADC3 for the
other PMICS on the system.
