This driver is for the wilc1000 which is a single chip IEEE 802.11 b/g/n device. The driver works together with cfg80211, which is the kernel side of configuration management for wireless devices because the wilc1000 chipset is fullmac where the MLME is managed in hardware. The driver worked from kernel version 2.6.38 and being now ported to several others since then. A TODO file is included as well in this commit. Signed-off-by:

if we load the module, unload and then again try to load the module, we will get a stackdump. In the module_exit function we are unregistering the device and releasing the parport. So when we reach the detach function parport is already null and the unregister_reboot_notifier() is never called. When we again try to load the module it again tries register_reboot_notifier() and gives us a stackdump as its earlier registration is still not removed. It was caused by the commit bb046fef ('staging: panel: register reboot') Fix this by moving all the unregistering and releasing in the detach function, which should be the ideal case as the detach will be called if we try to unregister the driver or if the parport is removed. Fixes: bb046fef ('staging: panel: register reboot') Signed-off-by:

The same area used for ioremap() is used for the MTRR area. Convert the driver from using the x86 specific MTRR code to the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add() will avoid MTRR if write-combining is available, in order to take advantage of that also ensure the ioremap'd area is requested as write-combining. There are a few motivations for this: a) Take advantage of PAT when available b) Help bury MTRR code away, MTRR is architecture specific and on x86 its replaced by PAT c) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442 titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()") The conversion done is expressed by the following Coccinelle SmPL patch, it additionally required manual intervention to address all the #ifdery and removal of redundant things which arch_phys_wc_add() already addresses such as verbose message about when MTRR fails and doing nothing when we didn't get an MTRR. @ mtrr_found @ expression index, base, size; @@ -index = mtrr_add(base, size, MTRR_TYPE_WRCOMB, 1); +index = arch_phys_wc_add(base, size); @ mtrr_rm depends on mtrr_found @ expression mtrr_found.index, mtrr_found.base, mtrr_found.size; @@ -mtrr_del(index, base, size); +arch_phys_wc_del(index); @ mtrr_rm_zero_arg depends on mtrr_found @ expression mtrr_found.index; @@ -mtrr_del(index, 0, 0); +arch_phys_wc_del(index); @ mtrr_rm_fb_info depends on mtrr_found @ struct fb_info *info; expression mtrr_found.index; @@ -mtrr_del(index, info->fix.smem_start, info->fix.smem_len); +arch_phys_wc_del(index); @ ioremap_replace_nocache depends on mtrr_found @ struct fb_info *info; expression base, size; @@ -info->screen_base = ioremap_nocache(base, size); +info->screen_base = ioremap_wc(base, size); @ ioremap_replace_default depends on mtrr_found @ struct fb_info *info; expression base, size; @@ -info->screen_base = ioremap(base, size); +info->screen_base = ioremap_wc(base, size); Generated-by: Coccinelle SmPL Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Cc: Teddy Wang <teddy.wang@siliconmotion.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Suresh Siddha <sbsiddha@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Juergen Gross <jgross@suse.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Dave Airlie <airlied@redhat.com> Cc: Antonino Daplas <adaplas@gmail.com> Cc: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: devel@driverdev.osuosl.org Cc: linux-fbdev@vger.kernel.org Cc: linux-kernel@vger.kernel.org Signed-off-by:

Most device functions pass bus_no and dev_no around and then do a lookup inside each function to find the dev_info struct. Instead just pass the pointer. This prepares us for a later conversion to using visor device. No real technical changes. Just function header changes and little cleanups as a result. Signed-off-by:

Convert the device attribute files to properly use visor_device. This removes a whole bunch of checks and assumptions and simplifies the code. Everything is straightforward. No testing down as I can't mimic channel info correctl. Signed-off-by:

There was a bunch of channel creation checks before the visorchannel_create function was called, moving some of those checks inside. This keeps the outside code cleaner and handles the situation where a caller forgets to make these checks. Signed-off-by:

This patch is an attempt to help hide the channel info behind accessory functions. I was trying to keep visorchannel as private as possible. The only function missing that seemed to be needed for now was the ability to set the clientpartition. So I expose that here. Signed-off-by:

If we are going to remove the bus_info structs than we need a way to find the devices when the *_create/destroy cmds are sent over the vmchannel. This function crudely impements what pci has. It takes a bus_no and dev_no and finds the matching 'struct visor_device'. This function can/should be optimzed later once we get our heads wrapped around its needs. For now, I am using dev_no=0 to mean the visorbus itself. The function is limited to chipset.c only because it is only needed to do the lookups upon receiving a vmchannel command. Future patches will make sure the resulting 'struct visor_device' is used every where else. Also allow visorbus_type to be more visible for use. Signed-off-by:

The visorbus driver has three _info structs lying around (device, bus, channel) that store subsets of info from the bigger structs. Having these structs around make resource handling very difficult and more complicated than it needs to be. Use the device infrastructure and instead pass 'struct visor_device' all over the place. In order to do that 'struct visor_device' needs to get smarter. This patch adds the pieces to prep for it. The new elements will be used in later patches. Signed-off-by:

Properly hook into the struct device groups element. This allows the core infrastructure to manage the files instead of the bus layer. And makes the code easier to read. I didn't clean up the _show functions just modified them a bit to handle the different args for now and to prevent a build warning. Signed-off-by:

Mimicing what other drivers do, this seems appropriate. Yeah, it is a bus, but it is a bus _device_. This makes things work better and smoother. Now the sysfs looks like [root@dhcp-17-174 visorbus]# ls -l /sys/bus/visorbus/devices/ total 0 lrwxrwxrwx. 1 root root 0 Apr 17 16:09 vbus1:dev2 -> ../../../devices/visorbus1/vbus1:dev2 lrwxrwxrwx. 1 root root 0 Apr 17 16:09 visorbus1 -> ../../../devices/visorbus1 Which looks correct. All the attributes are still correct too, based on my very minimal testing of 'ls -lR'. :-) Signed-off-by:

This patch moves the attributes to underneath the bus device correctly. This will help remove a bunch of cruft from the code and let the kernel infrastructure manage the sysfs files instead of the driver. After the move remove all the leftover code. Signed-off-by:
