They don't require the "adc-chan" part (although dt nodes are supposed to have
common names and adc-chan is used for adc for that; and dt node names are not
supposed to have underscores), but this validation error happens without this
commit:
<snip>/arch/arm/boot/dts/qcom-apq8084-ifc6540.dtb: pma8084@0: adc@3100:
'oneOf' conditional failed, one must be fixed:
'#address-cells', '#size-cells', 'die_temp', 'ref_1250v', 'ref_625mv',
'ref_buf_625mv', 'ref_gnd', 'ref_vdd' do not match any of the regexes:
'pinctrl-[0-9]+'
'die_temp', 'ref_1250v', 'ref_625mv', 'ref_buf_625mv', 'ref_gnd',
'ref_vdd' do not match any of the regexes: '^.*@[0-9a-f]+$', 'pinctrl-[0-9]+'
'qcom,spmi-iadc' was expected
From schema: <snip>/Documentation/devicetree/bindings/mfd/qcom,spmi-
pmic.yaml
So while e.g. ref-vdd@15 would also work, adc-chan@15 is more correct.
