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.

Add of_driver_match_device() helper function. This function can be used by bus types to determine if a driver works with a device when using OF style matching.

Now that the of_node pointer is part of struct device, of_device_get_modalias could be used on any struct device that has the device node pointer set.

The of_node pointer is now stored directly in struct device, so of_match_device() should work with any device, not just struct of_device. This patch changes the interface to of_match_device() to accept a struct device instead of struct of_device. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead.

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.

Create /sys/bus/of_platform/devices/*/modalias file to allow autoloading of modules. Modalias files are already present for many other bus types. This adds also a newline to the devspec files. Also create a devspec file for mac-io devices. They were created as a side effect. Use correct buffer size for mac-io modalias buffer. Tested on iBook1 and Efika.

Similar to of_find_compatible_node(), of_find_matching_node() and for_each_matching_node() allow you to iterate over the device tree looking for specific nodes, except that they take of_device_id tables instead of strings. This also moves of_match_node() from driver/of/device.c to driver/of/base.c to colocate it with the of_find_matching_node which depends on it.

This moves all the common parts for the Sparc, Sparc64 and PowerPC of_device.c files into drivers/of/device.c. Apart from the simple move, Sparc gains of_match_node() and a call to of_node_put in of_release_dev(). PowerPC gains better recovery if device_create_file() fails in of_device_register().

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.

This converts the usage of struct of_match to struct of_device_id, similar to pci_device_id. This allows a device table to be generated, which can be parsed by depmod(8) to generate a map file for module loading.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
