video: move fbdev to drivers/video/fbdev

2014-04-17T05:10:19+00:00

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.

video: wm8505fb: Remove redundant of_match_ptr

The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat Cc: Ed Spiridonov Signed-off-by: Tomi Valkeinen

video: replace strict_strtoul() with kstrtoul()

2013-06-26T12:19:48+00:00

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Signed-off-by: Tomi Valkeinen

video: wm8505fb: Convert to devm_ioremap_resource()

2013-04-10T08:15:49+00:00

Use the newly introduced devm_ioremap_resource() instead of devm_request_and_ioremap() which provides more consistent error handling. Signed-off-by: Sachin Kamat Acked-by: Tony Prisk Signed-off-by: Tomi Valkeinen

video: fb: vt8500: Convert framebuffer drivers to standardized binding

2013-04-04T10:07:34+00:00

Now that a display timing binding is available, convert our almost identical binding to use the standard binding. This patch converts the vt8500 and wm8505 framebuffer drivers and associated dts/dtsi files to use the standard binding as defined in bindings/video/display-timing.txt. There are two side-effects of making this conversion: 1) The fb node should now be in the board file, rather than the soc file as the display-timing node is a child of the fb node. 2) We still require a bits per pixel property to initialize the framebuffer for the different lcd panels. Rather than including this as part of the display timing, it is moved into the framebuffer node. I have also taken the opportunity to alphabetise the includes of each driver to avoid double-ups.

video: vt8500: Adjust contrast in wm8505 framebuffer driver.

2013-04-04T10:07:34+00:00

The contrast value was typo'd on the original commit (0x80 instead of 0x08). Following feedback from an enduser, a value of 0x10 seems more suitable due to the default backlight being <100%. Signed-off-by: Tony Prisk Reviewed-by: Jean-Christophe Plagniol-Villard Signed-off-by: Tomi Valkeinen

drivers/video/wm8505fb.c: use devm_ functions

2013-04-04T10:07:34+00:00

The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. The patch makes some other cleanups. First, the original code used devm_kzalloc, but kfree. This would lead to a double free. The problem was found using the following semantic match (http://coccinelle.lip6.fr/): // @@ expression x,e; @@ x = devm_kzalloc(...) ... when != x = e ?-kfree(x,...); // The error-handing code of devm_request_and_ioremap does not print any warning message, because devm_request_and_ioremap does this. The call to dma_alloc_coherent is converted to its devm equivalent, dmam_alloc_coherent. This implicitly introduces a call to dmam_free_coherent, which was completly missing in the original code. A semicolon is removed at the end of the error-handling code for the call to dma_alloc_coherent. The block of code calling fb_alloc_cmap is moved below the block of code calling wm8505fb_set_par, so that the error-handing code of the call to wm8505fb_set_par can just return ret. This way there is only one block of error-handling code that needs to call fb_dealloc_cmap, and so this is moved up to the place where it is needed, eliminating the need for all gotos and labels in the function. This was suggested by Tony Prisk. The initializations of fbi and ret at the beginning of the function are not necessary and are removed. The call platform_set_drvdata(pdev, NULL); at the end of the function is also removed. Signed-off-by: Julia Lawall Signed-off-by: Tony Prisk Signed-off-by: Tomi Valkeinen

With the conversion to devicetree only for arch-vt8500, this header is no longer required. This patch removes the #include from the two framebuffer drivers that used it, and the header file. Signed-off-by: Tony Prisk Reviewed-by: Jean-Christophe Plagniol-Villard Signed-off-by: Tomi Valkeinen

Drivers: video: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman
