* of: change of_match_device to work with struct deviceGrant Likely2010-05-223-11/+8
| | | | | | | | | | 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: Grant Likely <grant.likely@secretlab.ca>
* of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-22109-287/+503
| | | | | | | | | | | | | | | | .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.

* drivercore: Add of_match_table to the common device driversGrant Likely2010-05-222-6/+6
| | | | | | | | | | 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.

* arch/powerpc: Move dma_mask from of_device into pdev_archdataGrant Likely2010-05-221-2/+2
| | | | | | | | | By moving dma_mask into pdev_archdata, and adding archdata to struct of_device, it makes it possible to substitute of_device with struct platform_device, which is a stepping stone to removing the of_platform bus entirely. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* of: eliminate of_device->node and dev_archdata->{of,prom}_nodeGrant Likely2010-05-183-3/+0
| | | | | | | | | | | | | This patch eliminates the node pointer from struct of_device and the of_node (or prom_node) pointer from struct dev_archdata since the node pointer is now part of struct device proper when CONFIG_OF is set, and all users of the old pointer locations have already been converted over to use device->of_node. Also remove dev_archdata_{get,set}_node() as it is no longer used by anything. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* of: Always use 'struct device.of_node' to get device node pointer.Grant Likely2010-05-18105-311/+321
| | | | | | | | | | | | 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.

* i2c/of: Allow device node to be passed via i2c_board_infoGrant Likely2010-04-282-0/+4
| | | | | | | | | | | | | | | | | The struct device_node *of_node pointer is moving out of dev->archdata and into the struct device proper. of_i2c.c needs to set the of_node pointer before the device is registered. Since the i2c subsystem doesn't allow 2 stage allocation and registration of i2c devices, the of_node pointer needs to be passed via the i2c_board_info structure so that it is set prior to registration. This patch adds of_node to struct i2c_board_info (conditional on CONFIG_OF), sets of_node in i2c_new_device(), and modifies of_i2c.c to use the new parameter. The calling of dev_archdata_set_node() from of_i2c will be removed in a subsequent patch when of_node is removed from archdata and all users are converted over.

* driver-core: Add device node pointer to struct deviceGrant Likely2010-04-282-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, platforms using CONFIG_OF add a 'struct device_node *of_node' to dev->archdata. However, with CONFIG_OF becoming generic for all architectures, it makes sense for commonality to move it out of archdata and into struct device proper. This patch adds a struct device_node *of_node member to struct device and updates all locations which currently write the device_node pointer into archdata to also update dev->of_node. Subsequent patches will modify callers to use the archdata location and ultimately remove the archdata member entirely.

* of/flattree: Make unflatten_device_tree() safe to call from any archGrant Likely2010-04-281-0/+15
| | | | | | | | | | | | | | | This patch makes unflatten_device_tree() safe to call from any arch setup code with the following changes: - Make sure initial_boot_params actually points to a device tree blob before unflattening - Make sure the initial_boot_params->magic field is correct - If CONFIG_OF_FLATTREE is not set, then make unflatten_device_tree() an empty static inline function. This patch also adds some additional debug output to the top of unflatten_device_tree(). Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current algorithm will sometimes "detect" that more chains are enabled than are really present in the device because, for unknown reasons, the ucode sends up all-zeroes signal values. The simplest way of solving this is to restrict the active chains mask to the chains we know are really present on the device. This fixes a bug with some devices where, since sometimes more chains are enabled than really present, the system would hang.

This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors.

So we add this dependancy also (and leave the driver in the ARM section for now). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

For example, on the Arcom Vulcan, the register is shared between the watchdog and the PCI reset line...

However the mask generation was not changed, so the mask was coming out as 0. This patch fixes it.

Fix this by clearing the requested buffer size to zero, but only at _IOR ioctls. This way, there is almost no runtime penalty to legitimate ioctls. The only legitimate _IOR is FW_CDEV_IOC_GET_CYCLE_TIMER with 12 or 16 bytes to memset. [Another way to fix this would be strict checking of argument size (and possibly direction) vs. command number. However, we then need a lookup table, and we need to allow for slight size deviations in case of 32bit userland on 64bit kernel.] Reported-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

To avoid this problem, check that the header length is properly aligned. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

This would be an instruction to queue zero packets which would not make sense. This prevents a division by zero in the OHCI driver.
