However the co-processors enter low-power modes independent to that of the application processor and their states are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior let's drop the load state power-domain and replace them with the qmp property for all SoCs supporting low power mode signalling. Due to the current broken load state implementation, we can afford the binding breakage that ensues and the remoteproc functionality will remain the same when using newer kernels with older dtbs.
