of/device: Rework to use common platform_device_alloc() for allocating devices

2010-10-21T17:10:10+00:00

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/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: Make of_device_make_bus_id() usable by other code.

2010-07-30T06:03:58+00:00

The AMBA bus should also use of_device_make_bus_id() when populating device
out of device tree data.  This patch makes the function non-static, and
adds a suitable prototype in of_device.h

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: remove asm/of_device.h

2010-07-24T15:57:52+00:00

It is mostly unused now.  Sparc has a few defines left in it, but they
can be moved to other headers.  Removing this header means that new
architectures adding CONFIG_OF support don't need to also add this
header file.

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: Move struct of_device define outside of CONFIG_OF_DEVICE test

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

Some code uses of_device even when CONFIG_OF_DEVICE is not set.  This
patch makes of_device valid all the time by moving it outside of the
ifdef CONFIG_OF_DEVICE test.

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.
