Regarding "naming/device tree compatibles", do you mean to add
compatible matching for particular ASIC and also for common ? 

Currently 

    compatible = "marvell,prestera"

is used as default, so may be

you mean to support few matching including particular silicon too, like ?


    compatible = "marvell,prestera"
    compatible = "marvell,prestera-ac3x"

Would you please give an example ?

Thank you,
