* viafb: add X server compatibility modeFlorian Tobias Schandinat2011-04-23
| | | | | | | | | | | This patch adds a config option to be compatible with X servers like OpenChrome. This is required as for example the X server does not handle things like disabled IGAs/PLLs resulting in a potential freeze on X startup. With this option disabled we can provide some nice features like power management and not reinitializing the hardware on every mode switch (taking long time, causing flickering).

* viafb: delete clock and PLL initializationFlorian Tobias Schandinat2011-04-01
| | | | | | | We do this also in the real program code so there is no reason to do it here too (and here it's hardly readable). Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: add engine clock supportFlorian Tobias Schandinat2011-03-25
| | | | | | | | This patch adds support for enabling and configuring the engine on VIAs IGPs. This is the main clock used for everything but pixel output. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: add VIA slapping capabilityFlorian Tobias Schandinat2011-03-24
| | | | | | | | | | | | | | | This patch introduces dummy functions to execute when we don't know what we should do (due to missing documentation). They do nothing but print a nice message in the log explaining the situation. To trigger this message initial power management support is activated which might save a bit energy by disabling PLL and clock if no device is configured to use them. Note: The message is only shown for the oldest IGPs CLE266 and K400 as for the other platforms there are reasonable assumptions how it does (hopefully) work.

* viafb: split clock and PLL code to an extra fileFlorian Tobias Schandinat2011-03-24
| | | | | | | | | | | This patch is a huge move operation with some rename and introduces an interface to still use the functions. This should be a step in the right direction to reuse the code whenever possible but cleanly separate code that differs on different platform and keeping the complexity as low as possible. pll_config was renamed to via_pll_config to keep the naming scheme.

* viafb: add primary/secondary clock on/off switchesFlorian Tobias Schandinat2011-03-23
| | | | | | | | This patch adds functions to enable/disable the display clocks. It also fixes a tiny bug that slipped in with a previous commit but could not yet have caused any problems. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: add clock source selection and PLL power management supportFlorian Tobias Schandinat2011-03-23
| | | | | | | | | | | | This patch adds some support for clock source selection as well as PLL power management. The code is unused at the moment but was successfully tested as far as possible. The implementation is according to the documentation for VX700, VX800, VX855, VX900. Probably the source selection works like this starting with K800 and the power managemennt at least since VX700. (guessed based on the initialization in viamode.c) Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

* viafb: call viafb_get_clk_value only in viafb_set_vclockFlorian Tobias Schandinat2011-03-23

* viafb: allow some pll calculationsFlorian Tobias Schandinat2011-03-23
| | | | | | | | | | | | | This patch allows calculating the pll multiplier within limits based on the previous table. All available information supports that it should be possible/sane to choose the multiplier free within some ranges. Storing the multiplier ranges instead of lots of pll configurations reduces the memory needed and may as well improve the performance. It is also expected to provide better pll values resulting in better frequencies for the connected devices. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* viafb: initialize margins correctFlorian Tobias Schandinat2011-03-21

* viafb: refresh rate bug collectionFlorian Tobias Schandinat2011-03-16

| * viafb: split pll configs upFlorian Tobias Schandinat2011-03-12
| | | | | | | | | | | | | | | | | | | | This patch splits the pll configs up on pll versions. This allows easy adding of other known good pll values. Additionally it made it possible to remove invalid configurations resulting in better behaviour for such cases. The resulting clocks are no longer stored resulting in some computing overhead on each mode change. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
| * viafb: remove duplicated clock storageFlorian Tobias Schandinat2011-03-12
| | | | | | | | | | | | | | | | 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>
| * viafb: always return the best possible clockFlorian Tobias Schandinat2011-03-12
| | | | | | | | | | | | | | | | | | | | Before this patch only clocks that perfectly match were used and if none existed this was not handled properly. This patch changes this to always use the closest clock supported. This should behave like before for clocks that have a perfect match but be much saner for clocks which are slightly off.

| * 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: factor lcd scaling parameters outFlorian Tobias Schandinat2011-03-09
| | | | | | | | | | | | | | | | These parameters are the same for all currently known VIA IGPs so it does not make any sense to store them with IGP specific data.

|/ | | | | | | | | | This patch removes all internal uses of another mostly artificial value.

* console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2011-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

* | kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

If a command line option of the form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided, the driver will look for that mode among those, available in the monitor EDID. This patch adds the ability to request the driver to use monitor's preferred mode by specifying 0 as width and hight in the above string. If that mode is not supported by the system, the driver will continue scanning through EDID modes, until it finds a suitable one.

| | * | OMAP: DSS2: Introduce omap_channel as an omap_dss_device parameter, add new ↵Sumit Semwal2011-01-10

A panel connects to one of the overlay managers of DSS through some interface block. On OMAP4, specifying the type of the display is not sufficient to conclude which manager the panel should be connected to. Hence, a new member 'channel' is introduced in omap_dss_device structure to determine which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe() uses this channel parameter to set the correct manager to the corresponding omap_dss_device. The channel parameter is used only once to ensure the correct managers are set for each panel. The parameter dssdev->manager->id will take care of ensuring that the panel and then the interface driver configures the correct DISPC channel. Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.
