RZ/G2UL ADC is almost identical to RZ/G2L, but it has 2 analog input channels compared to 8 channels on the RZ/G2L. Signed-off-by: Biju Das --- v3->v4: * Removed unnecessary SoC specific reg description as it is equivalent to the logic used in reg. * Removed Items from reg. v2->v3: * Added generic description for reg. * Improved schema validation by restricting both channel and reg to [0-1]. v1->v2: * Started using generic compatible for RZ/G2UL and added SoC specific validation for channels. --- .../bindings/iio/adc/renesas,rzg2l-adc.yaml | 30 ++++++++++++++++--- 1 file changed, 26 insertions(+), 4 deletions(-) diff --git a/Documentation/devicetree/bindings/iio/adc/renesas,rzg2l-adc.yaml b/Documentation/devicetree/bindings/iio/adc/renesas,rzg2l-adc.yaml index d66c24cae1e1..ae6226c1044e 100644 --- a/Documentation/devicetree/bindings/iio/adc/renesas,rzg2l-adc.yaml +++ b/Documentation/devicetree/bindings/iio/adc/renesas,rzg2l-adc.yaml @@ -19,6 +19,7 @@ properties: compatible: items: - enum: + - renesas,r9a07g043-adc # RZ/G2UL - renesas,r9a07g044-adc # RZ/G2L - renesas,r9a07g054-adc # RZ/V2L - const: renesas,rzg2l-adc @@ -76,16 +77,37 @@ patternProperties: properties: reg: description: | - The channel number.
