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.

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

viafb: modetable conversion

2012-03-08T18:41:35+00:00

This patch converts the modetables used in viafb to - remove the strange thing that sync_end and blanking_end contained the length and not the absolute value - remove hundreds of useless defines - use fb_videomode and not our own definition so modes defined in the subsystem and received via EDID are compatible with ours As the modes are now stored in a flat structure and no longer in a tree like thing the lookup time was increased but as it is a rare event anyway it shouldn't matter. Otherwise the behaviour should be the same as before. Signed-off-by: Florian Tobias Schandinat

viafb: make single framebuffer multiple adapter mode work

2012-02-10T19:28:39+00:00

This patch implementes this mode (viafb_SAMM_ON set and viafb_dual_fb not set) in a useful way for CRT and DVI devices. The same content is shown on both devices in different video modes. The first (primary) resolution must not be bigger than the secondary one and determines the visible region. The same content is shown centered on the secondary output.

viafb: use information in var for modesetting

2011-08-07T01:51:41+00:00

This patch starts to use the information in var for modesetting for CRT and DVI devices. This is the right thing as it allows us to use more generic modes than the ones predefined by VIA. We do not yet allow more generic modes as check_var still limits them to the predefined ones but with this patch applied it would be really easy to do so. A problem was VIAs SAMM mode as it has 2 different modes but just one frame buffer device. This is solved by creating a pseudo var which contains enough information to use it for modesetting. Hopefully one day we can use information in var for all modes that do not involve hardware scaling. Well I'd like to say that the chance of regressions is low but it is quite likely that the behaviour in some cases changed especially when SAMM is involved. I hope we made it better than before in particular the DVI frequency check was probably broken before and hopefully works better now. Signed-off-by: Florian Tobias Schandinat

viafb: simplify viafb_fill_crtc_timing

2011-08-05T12:47:27+00:00

As the first argument is just part of the structure passed as the second argument there is no need for it at all. Signed-off-by: Florian Tobias Schandinat

viafb: replace custom return values

2011-03-27T03:36:00+00:00

This patch replaces OK/FAIL by true/false which is simpler and saner. Signed-off-by: Florian Tobias Schandinat

viafb: remove unused max_hres/vres

2011-03-23T13:04:35+00:00

This patch removes the max_hres and max_vres which are not used at the moment. In general they could be useful but it would be better to get them via any standard EDID implementation and not the buggy incomplete one currently used which is also removed as far as possible.

viafb: remove duplicated clock storage

2011-03-12T10:22:06+00:00

The clocks can be easily recalculated by the timing and refresh value. This brings us one step closer to removing VIAs modetable and use generic ones and being easier extensible. Signed-off-by: Florian Tobias Schandinat

viafb: introduce per output device power management

2010-09-24T02:15:03+00:00

This patch moves common parts of dvi.c, lcd.c and vt1636.c to hw.c to start a per output device power management. There should be no runtime changes aside that this patch enables the proc interface to enable/disable devices when needed which greatly increases the chances that changes to the output device configuration will work. However the power management is not yet complete so it might fail on some configurations. As this area is quite complex and touches undocumented things there is a slight chance of regressions.
