[DRIVER MODEL] Add platform_driver

2005-11-09T17:23:39+00:00

Introduce struct platform_driver.  This allows the platform device
driver methods to be passed a platform_device structure instead of
instead of a plain device structure, and therefore requiring casting
in every platform driver.

We introduce this in such a way that any existing platform drivers
registered directly via driver_register continue to work as before,
thereby allowing a gradual conversion to the new platform_driver
methods.

[DRIVER MODEL] Improved dynamically allocated platform_device interface

2005-11-05T21:19:33+00:00

Re-jig the simple platform device support to allow private data
to be attached to a platform device, as well as allowing the
parent device to be set.

Example usage:

	pdev = platform_device_alloc("mydev", id);
	if (pdev) {
		err = platform_device_add_resources(pdev, &resources,
						    ARRAY_SIZE(resources));
		if (err == 0)
			err = platform_device_add_data(pdev, &platform_data,
						       sizeof(platform_data));
		if (err == 0)
			err = platform_device_add(pdev);
	} else {
		err = -ENOMEM;
	}
	if (err)
		platform_device_put(pdev);

Manual #include fixups for clashes - there may be some unnecessary

[PATCH] fix missing includes

2005-10-31T01:37:32+00:00

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks

2005-10-28T16:52:56+00:00

In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

[PATCH] drivers/base - fix sparse warnings

2005-10-28T16:52:55+00:00

There are a number of sparse warnings from the latest sparse
snapshot being generated from the drivers/base build. The
main culprits are due to the initialisation functions not
being declared in a header file.

Also, the firmware.c file should include 
to get the prototype of  firmware_register() and
firmware_unregister().

This patch moves the init function declerations from the
init.c file to the base.h, and ensures it is included in
all the relevant c sources. It also adds 
to the included headers for firmware.c.

The patch does not solve all the sparse errors generated,
but reduces the count significantly.

[PATCH] export platform_add_devices

2005-04-19T04:57:32+00:00

platform_add_devices can be used from within modules, so it should be
exported.  This can for example happen if you have hotpluggable firmware in
an FPGA on a system on chip processor; in our case the FPGA is probed for
devices and the FPGA base code registers the devices it has found with the
kernel.  

(akpm: I think this is reasonable from a licensing POV: it's unlikely that
anyone would be interested in merging such specialised modules into mainline,
and it's a GPL export).
