* viafb: modetable conversionFlorian Tobias Schandinat2012-03-08
| | | | | | | | | | | | | | | | 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 <FlorianSchandinat@gmx.de>
* viafb: get rid of the remaining modetable structure assumptionsFlorian Tobias Schandinat2011-08-07
| | | | | | | | | | | This patch removes the remaining places where assumptions about the structure of the modetable were made. Aside from some places where assumptions are made that certain modes are in the modetable the only code dealing with the modetable and not just a single mode is in viamode. This will allow chaniging the modetable and use other sources for videomodes like the subsystem or EDID. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: add new funcions to select a single modeFlorian Tobias Schandinat2011-08-06
| | | | | | | | | | | | | | This patch introduces 2 new functions for selecting a single mode based on hres, vres and refresh rate and changes some uses to use those. The advantage is that it is less error prone than doing the selection based on refresh rate everywhere and allows replacing the modetable structure. This includes a little change that users may notice: If a refresh rate was given as module parameters but does not exist in the modetable prior to this patch a refresh rate of 60 was assumed and after this patch the closest supported refresh rate to the one provided by the user is used.

* viafb: remove duplicated clock informationFlorian Tobias Schandinat2011-03-12
| | | | | | | | | This patch removes the direct lookup table for resolution+refresh and pixclock by calculating this information from the mode table. Removes a lot of dupllication and error potential by just doing a little more calculations on each mode change. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: split global index upFlorian Tobias Schandinat2010-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first step to remove an artificial global index that was used in two ways: 1. As a pseudo index in the mode table. Pseudo as you had to search through the table to find the referenced entry. This was replaced by using a pointer to the entry. 2. As a shortcut to compare a combination of horizontal and vertical resolution at the same time. This was replaced by a "(hres<<16) | vres" which is good enough for now and the near future. If vres or hres become greater than 2^16 this might indeed cause problems but this solution allows to split this indexing mess up without the requirement to do even more code changes. This is a big change that will allow more clean ups. It should be a bit faster but that is probably not relevant for normal operation. No regressions expected but as this is a relatively big step heavy testing is appreciated.

* viafb: clean up viamode.hFlorian Tobias Schandinat2009-09-23
| | | | | | | | | | | | | | | Remove unneeeded declarations from the header and makes it more maintainable by evaluating the array size in the file the array exist in and exporting it via variables. This removes the need to keep the array size in the header in sync with the real array size.

* viafb: remove duplicated CX700 register initFlorian Tobias Schandinat2009-09-23
| | | | | | | | | | | | | | | | | | The current code initializes the register for CX700 chips 2 times due to a missing break as discovered by Harald Welte. As CX700 and VX800 have exactly the same register initialization we can use one for both to avoid duplicated code. As this is a pure code cleanup no measurable runtime effects are expected.
