[PATCH net-next v2 4/9] dt-bindings: net: add OPEN Alliance 10BASE-T1x MAC-PHY Serial Interface

From: Parthiban Veerasooran
Date: Mon Oct 23 2023 - 11:48:12 EST


Add DT bindings OPEN Alliance 10BASE-T1x MACPHY Serial Interface
parameters. These are generic properties that can apply to any 10BASE-T1x
MAC-PHY which uses OPEN Alliance TC6 specification.

+ chunk payload size is 8 bytes or N = 3. The default data chunk
+ payload size is 64 bytes, or N = 6. The minimum supported data chunk
+ payload size for this MAC-PHY device is indicated in the CPSMIN
+ field of the CAPABILITY register. Valid values for this parameter
+ are 8, 16, 32 and 64. All other values are reserved.
