* video/via: Convert to kstrtou8_from_userPeter Huewe2012-05-081-22/+12
| | | | | | | | | | This patch replaces the code for getting an number from a userspace buffer by a simple call to kstrou8_from_user. This makes it easier to read and less error prone.

| * viafb: avoid refresh and mode lookup in set_parFlorian Tobias Schandinat2012-03-081-18/+14
| | | | | | | | | | | | | | | | | | As check_var already ensures that the mode is valid there is no need to do those expensive lookups here again. The only thing that might change is that the deprecated interface could report slightly different refresh rates due to rounding errors.

| * viafb: modetable conversionFlorian Tobias Schandinat2012-03-087-1035/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: add auxiliary device management infrastructureFlorian Tobias Schandinat2012-02-1014-1/+626
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the basic infrastructure and a few stub drivers for devices that are connected via I2C busses. The infrastructure will be used to replace and extend the support that is scattered throughout viafb. The stub drivers are not very useful yet but they show how the infrastructure works, provide information about the chips integrated into a system and maybe gather some testers as it would be very difficult for a single person to get a sane test environment. The only thing this actually does is probing the I2C busses which will hopefully not cause any regressions. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

* viafb: correct sync polarity for OLPC DCONDaniel Drake2011-11-221-2/+2
| | | | | | | | | | | | | | | | | | | While the OLPC display appears to be able to handle either positive or negative sync, the Display Controller only recognises positive sync. This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and fixes a recent regression where the XO-1.5 DCON could no longer be frozen. Thanks to Florian Tobias Schandinat for helping identify the fix. Test case: from a vt, echo 1 > /sys/devices/platform/dcon/freeze should cause the current screen contents to freeze, rather than garbage being displayed.

Both families have only "long long" and "long" variants, but users want strtou8() 4. Both "simple" and "strict" prefixes are wrong: Simple doesn't exactly say what's so simple, strict should not exist because conversion should be strict by default. The solution is to use "k" prefix and add convertors for more types. Enter kstrtoull() kstrtoll() kstrtoul() kstrtol() kstrtouint() kstrtoint() kstrtou64() kstrtos64() kstrtou32() kstrtos32() kstrtou16() kstrtos16() kstrtou8() kstrtos8() Include runtime testsuite (somewhat incomplete) as well. strict_strto*() become deprecated, stubbed to kstrto*() and eventually will be removed altogether. Use kstrto*() in code today! Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if they'll be unused at runtime. This is temporarily solution, because I don't want to hardcode list of archs where these functions aren't needed. Current solution with sizeof() and __alignof__ at least always works.

* | | | viafb: get rid of the remaining modetable structure assumptionsFlorian Tobias Schandinat2011-08-077-33/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: eliminate modetable dependancy of LCD modesettingFlorian Tobias Schandinat2011-08-073-22/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the need for knowing the modetable structure within the LCD modesetting function. The magic 60Hz refresh rate was already there as always the first entry for a resolution was choosen based on the ascending refresh rate ordering in the modetable. For all but one this is at least 60Hz, if only higher frequencies available we choose those like the code before did. The exception is OLPC but that resolution has only one frequency so we get the same behaviour there as well. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* | | | viafb: seperate hardware initializationFlorian Tobias Schandinat2011-08-071-20/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits the hardware initialization out of the modesetting function which will make it easier to make it conditional and not require starting from scratch for every mode change, which is especially annoying in dual framebuffer mode. This required some minor reordering but it should not influence its functionality. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* | | | viafb: use information in var for modesettingFlorian Tobias Schandinat2011-08-074-83/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | | viafb: add new funcions to select a single modeFlorian Tobias Schandinat2011-08-065-61/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 640x480-60 CRT special caseFlorian Tobias Schandinat2011-08-052-15/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timing for 640x480-60 was handled different than all others. This patch changes this by changing the blanking start and end. The reason for this is that I can't find any reason for the old behaviour and it was not consistent anyway as the special case for LCD did not always trigger as the LCD code does not use this function and it did trigger regardless of whether the display set is CRT or LCD but only based whether any DVI/LCD device exists. There are no negative effects observed for CRT or DVI devices. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
