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: sa1100fb: use dev_get_platdata()

2013-09-20T09:22:02+00:00

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han Signed-off-by: Tomi Valkeinen

video: remove unnecessary platform_set_drvdata()

2013-06-26T11:44:40+00:00

The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

fbdev/sa1100fb: use vm_iomap_memory()

2013-04-24T05:41:41+00:00

Use vm_iomap_memory() instead of [io_]remap_pfn_range(). vm_iomap_memory() gives us much simpler API to map memory to userspace, and reduces possibilities for bugs. Signed-off-by: Tomi Valkeinen Acked-by: Russell King

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

FB: sa11x0: convert to use platform resource and ioremap()

2012-02-24T09:39:59+00:00

Convert the sa11x0 framebuffer driver to obtain the base address of its hardware registers from the platform resources, and ioremap this rather than relying on the static mappings. Signed-off-by: Russell King

FB: sa11x0: convert shannon display enable accesses to use GPIO subsystem

2012-02-21T11:56:21+00:00

Rather than accessing GPSR and GPCR directly, use the GPIO subsystem instead. Acked-by: Florian Tobias Schandinat Signed-off-by: Russell King

FB: sa11x0: fix shannon GPSR/GPCR accesses

2012-02-21T11:56:21+00:00

The GPIO set and clear registers should only be written, rather than read, modified, and written. A read-modify-write will have undesired side effects. Acked-by: Florian Tobias Schandinat Signed-off-by: Russell King

FB: sa1100: make GPIO configuration setting safe

2012-02-21T11:56:21+00:00

The sa1100fb driver needs to set the GPIO direction and alternate function register according to the panel that we're driving. We've done this in the driver by read-modify-writing the register, which may cause problems with races. Fix this with a minimal change.

FB: sa1100: use inf members directly

2012-02-21T11:56:21+00:00

Now that the LCD information is available while the driver is loaded, we don't need to cache that information into our driver private data structure. Get rid of it. Acked-by: Florian Tobias Schandinat Signed-off-by: Russell King
