RTD1295 family will want to check the ISO_CHIP_INFO1 register. Signed-off-by: Andreas Färber --- A SoC specific binding would defeat the purpose of the generic Linux driver detecting the SoC based on registers. Simply allowing it all for SoC families seems the most flexible. v1 -> v2: * Instead of extending reg, allow optional iso-syscon property for RTD129x. Iso syscon currently does not have a compatible, and it may need to differ across SoC families. .../bindings/soc/realtek/realtek,rtd1195-chip.yaml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/devicetree/bindings/soc/realtek/realtek,rtd1195-chip.yaml b/Documentation/devicetree/bindings/soc/realtek/realtek,rtd1195-chip.yaml index 86a1de214782..dfe33c95f68d 100644 --- a/Documentation/devicetree/bindings/soc/realtek/realtek,rtd1195-chip.yaml +++ b/Documentation/devicetree/bindings/soc/realtek/realtek,rtd1195-chip.yaml @@ -11,6 +11,7 @@ maintainers: description: | The Realtek DHC SoCs have some registers to identify the chip and revision. + To identify the exact model within a family, further registers are needed. properties: compatible: @@ -19,6 +20,8 @@ properties: reg: maxItems: 1 + iso-syscon: true + required: - compatible - reg @@ -31,4 +34,10 @@ examples: compatible = "realtek,rtd1195-chip"; reg = <0x1801a200 0x8>; }; + - | + chip-info@9801a200 { + compatible = "realtek,rtd1195-chip"; + reg = <0x9801a200 0x8>; + iso-syscon = <&iso>; + }; ...
