fbdev/for-next Various fbdev changes for 3.11 * xilinxfb updates * Small cleanups and fixes to multiple drivers

into fbdev/for-next OMAP display subsystem changes for 3.11 (part 2/2) This is the second part of OMAP DSS changes for 3.11. This part contains the new DSS device model support. The current OMAP panel drivers use a custom DSS bus, and there's a hard limit of one external display block per video pipeline. In the new DSS device model the devices/drivers are made according to the control bus of the display block, usually platform, i2c or spi. The display blocks can also be chained so that we can have separate drivers for setups with both external encoder and panel. To allow the current board files, which use the old style panels, to function, the old display drivers are left in their current state, and new ones are added to drivers/video/omap2/displays-new/. When the board files have been converted to use the new style panels, we can remove the old code. This is planned to happen in v3.12. Having to support two very different DSS device models makes the driver somewhat confusing in some parts, and prevents us from properly cleaning up some other parts. These cleanups will be done when the old code is removed. The new device model is designed with CDF (Common Display Framework) in mind. While CDF is still under work, the new DSS device model should be much more similar to CDF's model than the old device model, which should make the eventual conversion to CDF much easier.

into fbdev/for-next OMAP display subsystem changes for 3.11 (part 1/2) This is the first part of OMAP DSS changes for 3.11. This part contains fixes, cleanups and reorganizations that are not directly related to the new DSS device model that is added in part 2, although many of the reorganizations are made to make the part 2 possible. There should not be any functional changes visible to the user except the few bug fixes. The main new internal features: - Display (dis)connect support, which allows us to explicitly (dis)connect a whole display pipeline - Panel list, which allows us to operate without the specific DSS bus - Combine omap_dss_output to omap_dss_device, so that we have one generic "entity" for display pipeline blocks

drm_get_connector_name now returns a const value, which causes the following compilation warning: drivers/gpu/drm/drm_fb_helper.c: In function ‘drm_fb_helper_parse_command_line’: drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of ‘fb_get_options’ discards ‘const’ qualifier from pointer target type [enabled by default] In file included from drivers/gpu/drm/drm_fb_helper.c:35:0: include/linux/fb.h:627:12: note: expected ‘char *’ but argument is of type ‘const char *’ As fb_get_options uses its name argument as read only, make it const.

2013-06-26OMAPDSS: DPI: Fix wrong pixel clock limitTomi Valkeinen
DPI is supposed to skip odd dividers in the clock path when the pixel clock is higher than 100MHz. The code, however, defines the pixel clock limit as 1MHz. This causes the driver to skip valid clock dividers, possibly making the pixel clock to be further away from the requested one than necessary. Fix the clock limit to 100MHz.

2013-06-17OMAPDSS: public omapdss_register_output()Tomi Valkeinen
In order to allow multiple display block in a video pipeline, we need to give the drivers way to register themselves. For now we have the omapdss_register_display() which is used to register panels, and dss_register_output() which is used to register DSS encoders. This patch makes dss_register_output() public (with the name of omapdss_register_output), which can be used to register also external encoders. The distinction between register_output and register_display is that a "display" is an entity at the end of the videopipeline, and "output" is something inside the pipeline. The registration and naming will be made saner in the future, but the current names and functions are kept to minimize changes during the dss device model transition.
