This is not a new HW, this is the same HW with different FW and interface to FW is different too. As you can see earlier discussion on this thread, new compatible was ruled out since it is the same HW IP. > > In other cases, just use existing properties, don't bring a third one. :/ Not sure which existing property you are referring to. There is no property to the best of my knowledge to deal with our scenario. Are you suggesting we reuse "qcom,controlled-remotely" property that is used in Qualcomm BAM DMA Controller for our case too? > > Best regards, > Krzysztof >
