2011-09-14iwlagn: merge iwl_pci_down and iwl_pci_removeEmmanuel Grumbach
The latter was the only place that called the first. The two functions were split when the iwl_pci_probe called iwl_pci_down upon failure in the probe. Since iwl_pci_probe undoes its work by itself, there is no need to split between iwl_pci_down, and iwl_pci_remove. Thanks to Pavel Roskin for pointing that out.

Move all the iwlXXX_abgn_cfg forward declaration to a separate file so that iwl-pci.c doesn't need to include iwl-agn.h that includes all iwl-dev.h This allows to provide real encapsulation.

2011-08-29iwlagn: bus layer chooses its transport layerEmmanuel Grumbach
Remove iwl_transport_register which was a W/A. The bus layer knows what transport to use. So now, the bus layer gives the upper layer a pointer to the iwl_trans_ops struct that it wants to use. The upper layer then, allocates the desired transport layer using iwl_trans_ops->alloc function. As a result of this, priv->trans, no longer exists, priv holds a pointer to iwl_shared, which holds a pointer to iwl_trans. This required to change all the calls to the transport layer from upper layer. While we were at it, trans_X inlines have been renamed to iwl_trans_X to avoid confusions, which of course required to rename the functions inside the transport layer because of conflicts in names. So the static API functions inside the transport layer implementation have been renamed to iwl_trans_pcie_X. Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is confusing since the registration doesn't mean to request IRQ, so I added a handler for that.

2011-08-29iwlagn: introduce struct iwl-shared - known by all layersEmmanuel Grumbach
This struct will hold pointers to all the layers, so that every layer will find the pointers it needs when calling another layer. Note that the drv_data set to struct device is now a pointer to struct iwl_shared. This solves of bug that I introduced in iwlagn: simplify the bus architecture Bug description: sysfs gets the the driver data from struct device. Till the aforementioned patch, dev_get_drvdata would return iwl_priv. After the patch, dev_get_drvdata return iwl_bus which is buggy since the sysfs handlers rely on this value, and sysfs handlers need iwl_priv. Now, dev_get_drvdata return iwl-shared. Since we have pointers to all the layers in iwl_shared, every layer will be able to get the pointer it needs: bus layer will gets iwl_bus from the PCI suspend callbacks, and the sysfs handlers will get the iwl_priv they need. In order to keep good encapsulation, we need to avoid to dereference iwl_priv from a different layer. This is why instead of including iwl-dev.h from iwl-shared.h, I added a forward declaration to iwl_priv. Moreover we keep type safety while providing encapsulation.

2011-08-29iwlagn: introduce iwl-shared.hEmmanuel Grumbach
It will hold declaration of functions and forward declaration of struct that are used by several layers. This will allow modules not to include iwl_priv. iwl_bus and iwl_trans are still visible to all. All the layers share the module parameters, move the struct to iwl-shared.h. Also add all module parameters to iwl_mod_params instead of having them as global static.

2011-07-21iwlagn: add comment to warn about WoWLAN in resume / suspend flowsEmmanuel Grumbach

2011-07-21iwlagn: iwl_bus holds drv_data as void * instead of iwl_privEmmanuel Grumbach

2011-07-21iwlagn: simplify the bus architectureEmmanuel Grumbach
Call iwl_probe with a ready iwl_bus struct. This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.
