From: Prathyush K <[email protected]> A new function pm_genpd_of_add_device_by_name is added to the pm_domain file. This function takes three parameters - target device to be added to genpd, a device node and the name of the property. This function reads the "propname" property from the device node and finds the corresponding genpd device node. The target device is then added to this genpd by calling __pm_genpd_of_add_device.
