2011-10-31staging: Add module.h to more drivers implicitly using it.Paul Gortmaker
This 2nd batch of implicit module.h users only appeared when we removed the unnecessary module.h from include/linux/miscdevice.h [The 1st batch is already present in Greg's staging tree.] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31staging: Add moduleparam.h to drivers/staging files as requiredPaul Gortmaker
These files are using moduleparam infrastructure and were getting that via the implicit module.h presence that we are phasing out. So they'll need to include moduleparam.h explicitly in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31staging: Add export.h for THIS_MODULE/EXPORT_SYMBOL to drivers/staging users.Paul Gortmaker
Lots of drivers have in the past expected the presence of basic things like THIS_MODULE and EXPORT_SYMBOL. With the header cleanup, they wont have these. Call out the include explicitly. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-26staging: gma500: gtt based hardware scrolling consoleAlan Cox
Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI. It works out nicely on the usual configurations are netbooks and tablets.

2011-09-26staging: gma500: frame buffer lockingAlan Cox
If we are the console then a printk can hit us with a spin lock held (and in fact the kernel will do its best to take printing lock). In that case we cannot politely sleep when synching after an accelerated op but must behave obnixously to be sure of getting the bits out.

2011-08-26gma500: Fix up suspend/resumeAlan Cox
This isn't ideal as we could do with deferring the power on a lot more on Oaktrail and Medfield. We can't however do that without fixing other things first. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-08-26gma500: Fix backlight crashAlan Cox
Initial changes to get backlight behaviour we want and to fix backlight crashes on suspend/resume paths. [Note: on some boxes this will now produce a warning about the backlight, this isn't a regression it's an unfixed but non harmful case I still need to nail] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-08-26gma500: kill bogus codeAlan Cox
During the power split ups and work a chunk of code escaped into the Poulsbo code path which it isn't for. On some devices such as the Dell mini-10 this causes problems. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-08-16gma500: kill MIPI interface typesAlan Cox
Kirill Shutemov found problems with the non-upstream IMG driver where the use of extra DRM encoder/connector types caused random crashes when the DRM layer tried to display their matching name. This removes the MIPI types matching the changes Pauli Nieminen made to the non upstream driver set. As Pauli points out: " MIPI (or DSI) is protocol specification on top of LVDS serial bus. That makes it resonable to call MIPI connectors and encoders LVDS." (and indeed they may also be HDMI convertors or similar when we want to report a more useful to end user result) Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-07-15gma500: More Moorestown muddle meddling means MM maybe might modesetAlan Cox
There are a least three different species we need to deal with and right now it seems the only way to sort them out is via DMI. Encapsulate the entire pile somewhere private and out of the way.

2011-07-15gma500: Add the Oaktrail HDMI supportAlan Cox

2011-07-15gma500: Make crtc count a property of the deviceAlan Cox
Octavian Purdila posted a patch that sets num_crtc to 1 for Moorestown, but Oaktrail has 2 so we need to split Oaktrail/Moorestown more sensibly, and also cope with some other differences later on. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
