Since we implemented our mtk-cmdq-mailbox driver with mailbox frameworks, one mbox channel bounds to a GCE HW thread. So if we want to request a mbox channel for using a GCE HW thread for secure irq handler in mtk-cmdq-mailbox driver itself, I think we need to add this property to DT. Regards, Jason-JH.Lin [snip]
