of/device: Replace struct of_device with struct platform_device

2010-08-06T15:25:50+00:00

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

of/device: Replace of_device with platform_device in includes and core code

2010-07-24T15:58:21+00:00

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.

of: Merge of_platform_bus_type with platform_bus_type

2010-07-24T15:57:51+00:00

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.

of/device: Add OF style matching helper function

2010-07-05T22:14:51+00:00

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.  If CONFIG_OF is unselected, then it is a nop.

of: Modify of_device_get_modalias to be passed struct device

2010-07-05T22:14:28+00:00

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.  This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.

of: change of_match_device to work with struct device

2010-05-22T06:10:41+00:00

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.

of: Always use 'struct device.of_node' to get device node pointer.

2010-05-18T22:10:44+00:00

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.

(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

OF-device: Don't overwrite numa_node in device registration

2008-10-31T05:12:01+00:00

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.

powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devices

2008-08-19T23:50:21+00:00

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.
