* video: move fbdev to drivers/video/fbdevTomi Valkeinen2014-04-171-399/+0
| | | | | | | | | | | | | | | | | | | | The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

* drivers/video/omap2: don't check resource with devm_ioremap_resourceWolfram Sang2013-05-181-5/+0
| | | | | | | devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* drivers: video: use module_platform_driver_probe()Fabio Porcedda2013-04-101-12/+1
| | | | | | | | | | | | | | | | This patch converts the drivers to use the module_platform_driver_probe() macro which makes the code smaller and a bit simpler.

* video: Convert to devm_ioremap_resource()Thierry Reding2013-01-221-5/+4
| | | | | | | | | | | | | Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

* OMAPDSS: VRFB: add omap_vrfb_supported()Tomi Valkeinen2012-10-171-0/+16
| | | | | | | | Add an exported function omap_vrfb_supported() which returns true if the vrfb driver has been loaded succesfully. This can be used to decide if VRFB can be used or not. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAP: move arch/arm/plat-omap/include/plat/vrfb.hTomi Valkeinen2012-10-171-1/+1
| | | | | | | | | Now that vrfb driver is not omap dependent anymore, we can move vrfb.h from arch/arm/plat-omap/include/plat to include/video/omapvrfb.h. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Vaibhav Hiremath <hvaibhav@ti.com>
* OMAP: VRFB: convert vrfb to platform deviceTomi Valkeinen2012-10-171-20/+104
| | | | | | | | | | | | | | This patch converts vrfb library into a platform device, in an effort to remove omap dependencies. The platform device is registered in arch/arm/plat-omap/fb.c and assigned resources depending on whether running on omap2 or omap3. The vrfb driver will parse those resources and use them to access vrfb configuration registers and the vrfb virtual rotation areas.

* OMAPDSS: VRFB: remove compiler warnings when CONFIG_BUG=nTomi Valkeinen2012-05-221-1/+3
| | | | | | | | | | | | | | If CONFIG_BUG is not enabled, BUG() does not stop the execution. Many places in code expect the execution to stop, and this causes compiler warnings about uninitialized variables and returning from a non-void function without a return value. This patch fixes the warnings by initializing the variables and returning properly after BUG() lines. However, the behaviour is still undefined after the BUG, but this is the choice the user makes when using CONFIG_BUG=n. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAP: Add support for VRFB rotation engineTomi Valkeinen2009-12-091-0/+315
VRFB rotation engine is a block in OMAP2/3 that offers 12 independent contexts that can be used for framebuffer rotation. Each context has a backend area of real memory, where it stores the pixels in undisclosed format. This memory is offered to users via 4 virtual memory areas, which see the same memory area in different rotation angles (0, 90, 180 and 270 degrees).
