      "message": "PM: Make system-wide PM and runtime PM treat subsystems consistently\n\nThe code handling system-wide power transitions (eg. suspend-to-RAM)\ncan in theory execute callbacks provided by the device\u0027s bus type,\ndevice type and class in each phase of the power transition.  In\nturn, the runtime PM core code only calls one of those callbacks at\na time, preferring bus type callbacks to device type or class\ncallbacks and device type callbacks to class callbacks.\n\nIt seems reasonable to make them both behave in the same way in that\nrespect.  Moreover, even though a device may belong to two subsystems\n(eg. bus type and device class) simultaneously, in practice power\nmanagement callbacks for system-wide power transitions are always\nprovided by only one of them (ie. if the bus type callbacks are\ndefined, the device class ones are not and vice versa).  Thus it is\npossible to modify the code handling system-wide power transitions\nso that it follows the core runtime PM code (ie. treats the\nsubsystem callbacks as mutually exclusive).\n\nOn the other hand, the core runtime PM code will choose to execute,\nfor example, a runtime suspend callback provided by the device type\neven if the bus type\u0027s struct dev_pm_ops object exists, but the\nruntime_suspend pointer in it happens to be NULL.  This is confusing,\nbecause it may lead to the execution of callbacks from different\nsubsystems during different operations (eg. the bus type suspend\ncallback may be executed during runtime suspend of the device, while\nthe device type callback will be executed during system suspend).\n\nMake all of the power management code treat subsystem callbacks in\na consistent way, such that:\n(1) If the device\u0027s type is defined (eg. dev-\u003etype is not NULL)\n    and its pm pointer is not NULL, the callbacks from dev-\u003etype-\u003epm\n    will be used.\n(2) If dev-\u003etype is NULL or dev-\u003etype-\u003epm is NULL, but the device\u0027s\n    class is defined (eg. dev-\u003eclass is not NULL) and its pm pointer\n    is not NULL, the callbacks from dev-\u003eclass-\u003epm will be used.\n(3) If dev-\u003etype is NULL or dev-\u003etype-\u003epm is NULL and dev-\u003eclass is\n    NULL or dev-\u003eclass-\u003epm is NULL, the callbacks from dev-\u003ebus-\u003epm\n    will be used provided that both dev-\u003ebus and dev-\u003ebus-\u003epm are\n    not NULL.\n\nSigned-off-by: Rafael J.

      "message": "PM: Add support for device power domains\n\nThe platform bus type is often used to handle Systems-on-a-Chip (SoC)\nwhere all devices are represented by objects of type struct\nplatform_device.  In those cases the same \"platform\" device driver\nmay be used with multiple different system configurations, but the\nactions needed to put the devices it handles into a low-power state\nand back into the full-power state may depend on the design of the\ngiven SoC.  The driver, however, cannot possibly include all the\ninformation necessary for the power management of its device on all\nthe systems it is used with.  Moreover, the device hierarchy in its\ncurrent form also is not suitable for representing this kind of\ninformation.\n\nThe patch below attempts to address this problem by introducing\nobjects of type struct dev_power_domain that can be used for\nrepresenting power domains within a SoC.  Every struct\ndev_power_domain object provides a sets of device power\nmanagement callbacks that can be used to perform what\u0027s needed for\ndevice power management in addition to the operations carried out by\nthe device\u0027s driver and subsystem.\n\nNamely, if a struct dev_power_domain object is pointed to by the\npwr_domain field in a struct device, the callbacks provided by its\nops member will be executed in addition to the corresponding\ncallbacks provided by the device\u0027s subsystem and driver during all\npower transitions.\n\nSigned-off-by: Rafael J.
