* viafb: rename display_timing to via_display_timingSteffen Trumtrar2013-01-241-1/+1
| | | | | | | | | | The struct display_timing is specific to the via subsystem. The naming leads to collisions with the new struct display_timing, which is supposed to be a shared struct between different subsystems. To clean this up, prepend the existing struct with the subsystem it is specific to. Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>
* Drivers: video: remove __dev* attributes.Greg Kroah-Hartman2013-01-041-5/+5
| | | | | | | | | | | | | | 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.

* viafb: modetable conversionFlorian Tobias Schandinat2012-03-081-46/+7Star
| | | | | | | | | | | | | | | | 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: LCD bpp cleanupFlorian Tobias Schandinat2012-03-041-13/+8Star

* viafb: eliminate modetable dependancy of LCD modesettingFlorian Tobias Schandinat2011-08-071-7/+5Star
| | | | | | | | | | | | | 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: kill viafb_load_crtc_timingFlorian Tobias Schandinat2011-08-051-22/+19Star
| | | | | | | | | This patch replaces calls to viafb_load_crtc_timing with the code. This should make it easier to fix the oddity that in the modetable the blank and sync end entries contain the length and we need to add the start values to get those to be written to the hardware.

| * viafb: remove duplicated clock storageFlorian Tobias Schandinat2011-03-121-3/+5

|/ | | | | | | | | | This patch removes all internal uses of another mostly artificial value. It does duplicate the information of the maximum resolution and it is not flexible as only a few resolutions exist. Hence it is better to remove it and clean the mess up. No runtime change expected.

* viafb: add initial VX900 supportFlorian Tobias Schandinat2010-10-241-0/+2
| | | | | | | | | | | | | | | This patch adds basic support for the new VX900 IGP. Almost everything that was implemented for other IGPs is expected to work also on VX900 after this patch. The only known issue is that on the CRT output mode setting does not always work. It is clear that the possibility for regressions is zero. A big thanks to VIA Technologies for making this possible and supporting this work.

* viafb: introduce per output device power managementFlorian Tobias Schandinat2010-09-241-10/+0Star
| | | | | | | | | | | | | | 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.

* viafb: limit LCD code impactFlorian Tobias Schandinat2010-09-241-31/+0Star

| | | | | | | | | | | This patch merges the remaining functionality of the output path function in the associated enabling functions. This is very natural as most of the remaining code does actually enable the device. Just some more or less intelligent code merge. If no stupid mistakes occured there should be no regressions.

* viafb: rework the I2C support in the VIA framebuffer driverHarald Welte2010-04-271-11/+8Star
| | | | | | | | | | | | | | | | | | | | This patch changes the way how the various I2C busses are used internally inside the viafb driver: Previosuly, only a single i2c_adapter was created, even though two different hardware I2C busses are accessed: A structure member in a global variable was modified to indicate the bus to be used. Now, all existing hardware busses are registered with the i2c core, and the viafb_i2c_{read,write}byte[s]() function take the adapter number as function call parameter, rather than referring to the global structure member.

* viafb: remove dead code due to IGA1_IGA2Florian Tobias Schandinat2010-03-131-556/+6Star
| | | | | | | | | | | | | | | | 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.

* viafb: split color mode setting upFlorian Tobias Schandinat2010-03-131-2/+0Star
| | | | | | | | | | | | | | | | | This patch splits color mode setting up in seperate functions. Some hardware initialization that was previously mixed with it is moved to viafb_setmode. As are the calls to the newly created function. This is yet another little step towards controlling each IGA on its own. As this patch really aims too mimic the old behaviour no regressions are expected. However I noticed that 8bpp (or 6bpp?) seems actually a bit broken before and after the patch.

* viafb: split global index upFlorian Tobias Schandinat2010-03-131-78/+70Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Also add a bit to the second pitch which the documentation mentions but which was ignored by the driver. Although it is a bit unclear what the right pitch for some LCD modes is this patch should have no negative runtime impact.

* viafb: improve viafb_parFlorian Tobias Schandinat2009-09-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces viafb_shared and is the beginning of a smooth transition to use it. viafb_shared should contain all general, non-surface specific data that should be shared along all viafb framebuffers while viafb_par should only contain things that are specific to each surface or in other words extend fb_info. This change is intended to clean the dual/multi framebuffer handling up. This removes the annoyance that viafbinfo1->par points to a different structure than viaparinfo1. As the last change is fundamental it is difficult to ensure that all parts of the driver do not depend on the previous brokenness but the chance of regressions is very low.
