For instance, consumer projects prioritize the A2DP SRC feature, while IoT projects focus on the A2DP SINK feature, which may have more optimizations for coexistence when acting as a SINK. Due to the patch size, it is not feasible to include all features in a single firmware. Therefore, the 'product-variant' devicetree property is used to provide product information for the Bluetooth driver to load the appropriate firmware. If this property is not defined, the default firmware will be loaded, ensuring there are no backward compatibility issues with older devicetrees. The product-variant defines like this: 0 - 15 (16 bits) are product line specific definitions 16 - 23 (8 bits) are for the product line. 24 - 31 (8 bits) are reserved for future use, 0 currently |---------------------------------------------------------------------| | 32 Bits | |---------------------------------------------------------------------| | 31 - 24 (bits) | 23 - 16 (bits) | 15 - 0 (16 bits) | |---------------------------------------------------------------------| | Reserved | 0: default | 0: default | | | 1: CE | | | | 2: IoT | | | | 3: Auto | | | | 4: Reserved | | |---------------------------------------------------------------------| Signed-off-by: Cheng Jiang --- .../bindings/net/bluetooth/qualcomm-bluetooth.yaml | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/Documentation/devicetree/bindings/net/bluetooth/qualcomm-bluet= ooth.yaml b/Documentation/devicetree/bindings/net/bluetooth/qualcomm-blueto= oth.yaml index 7bb68311c609..9019fe7bcdc6 100644 --- a/Documentation/devicetree/bindings/net/bluetooth/qualcomm-bluetooth.ya= ml +++ b/Documentation/devicetree/bindings/net/bluetooth/qualcomm-bluetooth.ya= ml @@ -110,6 +110,12 @@ properties: description: boot firmware is incorrectly passing the address in big-endian order =20 + qcom,product-variant: + $ref: /schemas/types.yaml#/definitions/uint32 + description: + specify the product information for driver to load the appropriate f= irmware + + required: - compatible =20 --=20 2.25.1
