of_device is currently just an #define alias to platform_device until it gets removed entirely. This patch removes references to it from the include directories and the core drivers/of code. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S. Miller <davem@davemloft.net>

There is an unlikely chance of this situation is occurring, but it is easy to protect against. If a matching entry cannot be found in the of_match_table, then don't bind the driver. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

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.

This patch fixes the condition where device tree support is compiled in, but no device tree was proved by firmware. It makes of_platform_bus_probe() explicitly check for a NULL device tree pointer. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

Commit 94c09319 (of: Merge of_device_alloc() and of_device_make_bus_id()) moved code that does calls a dcr routine without including the correct header which causes the following build error on some powerpc configurations: drivers/of/platform.c: In function 'of_device_make_bus_id': drivers/of/platform.c:437: error: implicit declaration of function 'of_translate_dcr_address' This patch adds the appropriate header to drivers/of/platform.c Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

When allocating a platform_device to represent an OF node, also allocate space for the resource table and populate it with IRQ and reg property information. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type so that existing platform_driver code can retrieve base addresses and IRQs data. Background: a previous commit removed struct of_device and made it a #define alias for platform_device.

Merge common code between PowerPC and microblaze. This patch merges the code that scans the tree and registers devices. The functions merged are of_platform_bus_probe(), of_platform_bus_create(), and of_platform_device_create(). This patch also move the of_default_bus_ids[] table out of a Microblaze header file and makes it non-static. The device ids table isn't merged because powerpc and microblaze use different default data.

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>

.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

OF-style matching can be available to any device, on any type of bus. This patch allows any driver to provide an OF match table when CONFIG_OF is enabled so that drivers can be bound against devices described in the device tree.

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.
