Is this acceptable for you? I understood that rationale behind this patch is "ACPI" thus that reply. This one sentence in commit msg is not helping. Entire binding description speaks about ACPI, so yeah - I don't care what ACPI does. Provide proper explanation/description of firmware or hardware, then sure. But the patch saying ACPI is doing something, so bindings will be doing the same is for me NAK. Whatever ACPI is doing is never a reason alone to do the same in Devicetree. Best regards, Krzysztof
