In some situations, userspace may want to resolve a device by function and logical number (ie, "serial0") rather than by the base address or full device path. Being able to resolve a device by alias frees userspace from the burden of otherwise having to maintain a mapping between device addresses and their logical assignments on each platform when multiple instances of the same hardware block are present in the system. Although the uevent device attribute contains devicetree compatible information and the full device path, the uevent does not list the alises that may have been defined for the device.

When userspace needs to find a specific device, it currently isn't easy to resolve a /sys/devices/ path from a specific device tree node. Nor is it easy to obtain the compatible list for devices. This patch generalizes the code that inserts OF_* values into the uevent device attribute so that any device that is attached to an OF node will have that information exported to userspace. Without this patch only platform devices and some powerpc-specific busses have access to this data. The original function also creates a MODALIAS property for the compatible list, but that code has not been generalized into the common case because it has the potential to break module loading on a lot of bus types. Bus types are still responsible for their own MODALIAS properties. Boot tested on ARM and compile tested on PowerPC and SPARC.

arch/powerpc/kernel/ibmebus.c is the only remaining user of the of_bus_type support code for initializing the bus and registering drivers. All others have either been switched to the vanilla platform bus or already have their own infrastructure. This patch moves the functionality that ibmebus is using out of drivers/of/{platform,device}.c and into ibmebus.c where it is actually used. Also renames the moved symbols from of_platform_* to ibmebus_bus_* to reflect the actual usage. This patch is part of moving all of the of_platform_bus_type users over to the platform_bus_type.

The current code allocates and manages platform_devices created from the device tree manually. It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.

of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.

Currently, the numa_node of OF-devices will be overwritten during device_register, which simply sets the node to -1. On cell machines, this means that devices can't find their IOMMU, which is referenced through the device's numa node. Set the numa node for OF devices with no parent, and use the lower-level device_initialize and device_add functions, so that the node is preserved. We can remove the call to set_dev_node in of_device_alloc, as it will be overwritten during register. Signed-off-by: NJeremy Kerr <jk@ozlabs.org> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.
