+ * Implementation of the SCU based Power Domains
+ *
+ * NOTE: a better implementation suggested by Ulf Hansson is using a
+ * single global power domain and implement the ->attach|detach_dev()
+ * callback for the genpd and use the regular of_genpd_add_provider_simple().
+ * From within the ->attach_dev(), we could get the OF node for
+ * the device that is being attached and then parse the power-domain
+ * cell containing the "resource id" and store that in the per device
+ * struct generic_pm_domain_data (we have void pointer there for
+ * storing these kind of things).
+ *
+ * Additionally, we need to implement the ->stop() and ->start()
+ * callbacks of genpd, which is where you "power on/off" devices,
+ * rather than using the above ->power_on|off() callbacks.
+ *
+ * However, there're two known issues:
+ * 1. The ->attach_dev() of power domain infrastructure still does
+ * not support multi domains case as the struct device *dev passed
+ * in is a virtual PD device, it does not help for parsing the real
+ * device resource id from device tree, so it's unware of which
+ * real sub power domain of device should be attached.
+ *
+ * The framework needs some proper extension to support multi power
+ * domain cases.
+ *
+ * 2. It also breaks most of current drivers as the driver probe sequence
+ * behavior changed if removing ->power_on|off() callback and use
+ * ->start() and ->stop() instead. genpd_dev_pm_attach will only power
+ * up the domain and attach device, but will not call .start() which
+ * relies on device runtime pm. That means the device power is still
+ * not up before running driver probe function. For SCU enabled
+ * platforms, all device drivers accessing registers/clock without power
+ * domain enabled will trigger a HW access error. That means we need fix
+ * most drivers probe sequence with proper runtime pm.
+ *
+ * In summary, we need fix above two issue before being able to switch to
+ * the "single global power domain" way.
