* of/platform: remove all of_bus_type and of_platform_bus_type referencesGrant Likely2010-07-24
| | | | | | | | | | | | | | | Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

* of: Merge of_platform_bus_type with platform_bus_typeGrant Likely2010-07-24
| | | | | | | | | | | | | | | | | | | | 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: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.

You generally have two cases where DDC lines are shared: - HDMI + VGA - HDMI + DVI-D HDMI + VGA is easy to deal with because you can check the EDID for the to see if the attached monitor is digital. A shared DDC line with two digital connectors is more complex. You can't use the hdmi bits in the EDID since they may not be there with DVI<->HDMI adapters. In this case all we can do is check the HPD pins to see which is connected as we have no way of knowing using the EDID.

The GART aperture size has to be in the form of 2^X bytes, where X is from 25 to 31 2. The GART aperture MC base has to be aligned to a boundary equal to the size of the aperture. 3. The GART page table has to be aligned to the boundary equal to the size of the table. 4. The GART page table size is: table_entry_size * (aperture_size / page_size) 5. The GART page table has to be allocated in non-paged, non-cached, contiguous system memory. This patch takes care 2. The rest should already be handled properly.

On such a path we call rt2x00lib_remove_dev() to free any resources initialized during the probe before we use INIT_WORK to initialize the workqueue. This causes lockdep to get confused since the lock used in the workqueue hasn't been initialized yet but is now being acquired during cancel_work_sync() called by rt2x00lib_remove_dev(). Fix this by initializing the workqueue first before we attempt to probe the device. This should make lockdep happy and avoid breaking any assumptions about how the library cleans up after a probe fails. phy0 -> rt2x00lib_probe_dev: Error - Failed to allocate device. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

This is because hostap_pci wasn't setting dev->base_addr, which is now checked in prism2_interrupt. As a result, initialization was failing for PCI-based hostap devices. This corrects that oversight.
