2011-08-07viafb: eliminate viafb_get_pixclockFlorian Tobias Schandinat1-4/+0
As there is only one user we can just insert the formula where needed. Avoids one lookup in the modetable and viafb_fill_var_timing_info does no longer depend on the modetable. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-08-05viafb: use more compact modesetting functionsFlorian Tobias Schandinat1-17/+2
This patch replaces the old timing setup code with a redesigned one. The new code might be slightly faster as it has no conditinals and does not write the same register multiple times. Also it makes the comparison to the documentation easier. Regressions are unlikely but could happen as a lot of hardware is undocumented.

This trivial patch removes unused mode tables. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2011-04-23viafb: reduce OLPC refresh a bitFlorian Tobias Schandinat1-0/+1
When allowing some PLL calculation we get a frequency that seems to be a bit higher than what the OLPC DCON likes resulting in a still readable but not so good image. We don't really know whether this is a problem with the calculation formula or the OLPC but as other displays seem to be happy with the other modes adjusting the OLPC refresh looks like the better thing. This patch prevents a regression when dynamic PLL calculation is allowed. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-03-27viafb: replace custom return valuesFlorian Tobias Schandinat1-8/+0
This patch replaces OK/FAIL by true/false which is simpler and saner. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-03-12viafb: remove duplicated clock storageFlorian Tobias Schandinat1-72/+0
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 <FlorianSchandinat@gmx.de>
2011-03-12viafb: remove duplicated clock informationFlorian Tobias Schandinat1-69/+0
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>
2010-07-23viafb: PLL value cleanupFlorian Tobias Schandinat1-309/+0
viafb: PLL value cleanup This is a big change of how PLL values are handled on the road to dynamic PLL value generation. The table was converted automatically in the relevant parameters for frequency generation. Sadly there were some bits set whose meaning is unknown. Those differences are documented but ignored as the unichrome code implies that they are not important (a big thanks to Luc for his amazing work). The PLL values for 31490000 and 133308000 are deleted as they were more than 5% off and not used anyway. The values for CX700@60466000 and VX855@153920000 are corrected as they were wrong and easily correctable as enough correct values was available because CX700 and VX855 support the same values only with a little difference in hardware format. All remaining values are not more than 2% off. Additionally the surrounding code is changed as needed especially the byte order of the values written to hardware to allow nicer conversion functions. This is mostly a change preparing for dynamic PLL generation and the two corrected values aside no runtime change is expected.

2010-05-07viafb: improve misc register handlingFlorian Tobias Schandinat1-2/+0
viafb: improve misc register handling This patch improves the misc register handling by adding a modify function for this to via_io.h and moving expanded definitions of the relevant ports there. The code was changed to use those to improve readability. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2010-03-12viafb: remove dead code due to IGA1_IGA2Florian Tobias Schandinat1-1/+0
Some code depended on IGA1_IGA2 which was never set (at least with the symbolic name). Remove this dead code although it might one day be useful to get a hint on how some things might work. However as this is dead it is likely full of bugs and would prevent a clean structure (as it has some very strange things). Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

2010-03-12viafb: remove the remaining VIA_RES_* usesFlorian Tobias Schandinat1-55/+0
Remove the rest of the VIA_RES_* use cases. Obviously this was no longer useful. Keep the related infrastructure/functions for later use. No runtime impact expected.
