Patch establishes a dummy netiucv device to make sure iucv is notified about suspend/resume even if netiucv is the only loaded iucv-exploting module without any real net_device defined. The PM freeze callback closes all open netiucv connections. Thus the corresponding iucv path is removed. The PM thaw/restore callback re-opens previously closed netiucv connections. Signed-off-by:

Patch calls the PM callback functions of iucv-bus devices, which are responsible for removal of their established iucv pathes. The PM freeze callback for the first iucv-bus device disables all iucv interrupts except the connection severed interrupt. The PM freeze callback for the last iucv-bus device shuts down iucv. The PM thaw callback for the first iucv-bus device re-enables iucv if it has been shut down during freeze. If freezing has been interrupted, it re-enables iucv interrupts according to the needs of iucv-exploiters. The PM restore callback for the first iucv-bus device re-enables iucv. Signed-off-by:

To guarantee a proper cleanup, patch adds a reboot notifier to the iucv base code, which disables iucv interrupts, shuts down established iucv pathes, and removes iucv declarations for z/VM. Checks have to be added to the iucv-API functions, whether iucv-buffers removed at reboot time are still declared. Signed-off-by:

The SCLP base driver defines a new notifier call back for all upper level SCLP drivers, like the SCLP console, etc. This guarantees that in suspend first the upper level drivers are suspended and afterwards the SCLP base driver. For resume it is the other way round. The SCLP base driver itself registers a new platform device at the platform bus and gets PM notifications via the dev_pm_ops. In suspend, the SCLP base driver switches off the receiver and sender mask This is done in sclp_deactivate(). After suspend all new requests will be rejected with -EIO and no more interrupts will be received, because the masks are switched off. For resume the sender and receiver masks are reset in the sclp_reactivate() function. When the SCLP console is suspended, all new messages are cached in the sclp console buffers. In resume, all the cached messages are written to the console. In addition to that we have an early resume function that removes the cached messages from the suspend image. Signed-off-by:

This patch implements suspend/hibernation for the vmwatchdog driver. The pm_notifier_callchain is used to get control on PM events. Since watchdog operation and suspend cannot work together in a reliable fashion, the open flag is also used to prevent suspend and open from happening at the same time. The watchdog can also be active with no open file descriptor. This patch adds another flag which is only changed in vmwdt_keep_alive and vmwdt_disable. Signed-off-by:

Introduce the power management callbacks to the 3215 console. On suspend the console buffer is flushed to the 3215 device to have an empty console buffer. Printks done while the 3215 device is suspended are buffered in the 64K buffer of the 3215 device. If the buffer is full new messages will push out the oldest messages to make room for the most recent message. On resume the buffered messages are printed. If the system panics before the 3215 device is resumed ccw_device_force_console is used to get the console working again. Signed-off-by: -

If something goes wrong in a suspend / resume cycle a ccw based console if very likely in the suspended state and cannot print anything. Introduce ccw_device_force_console to force the wake up of the console device to be able to print the oops message. The console device drivers should use this function only if the system paniced.

Introduce the power management callbacks to the dasd driver. On suspend the dasd devices are stopped and removed from the focus of alias management. On resume they are reinitialized by rereading the device characteristics and adding the device to the alias management. In case the device has gone away during suspend it will caught in the suspend state with stopped flag set to UNRESUMED. After it appears again the restore function is called again. Signed-off-by:

The V3 regulator can be configured with an external resistor connected to the feedback pin (R24 in the data sheet) to increase the voltage range. For example, hx4700 has R24 = 3.32 kOhm to achieve a maximum V3 voltage of 1.55 V which is needed for 624 MHz CPU frequency. Signed-off-by:

In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.
