into fbdev-next Omapdss driver changes for the 3.7 merge window. Notable changes: * Basic writeback support for DISPC level. Writeback is not yet usable, though, as we need higher level code to actually expose the writeback feature to userspace. * Rewriting the omapdss output drivers. We're trying to remove the hard links between the omapdss and the panels, and this rewrite work moves us closer to that goal. * Cleanup and restructuring patches that have been made while working on device tree support for omapdss. Device tree support is still some way ahead, but these patches are good cleanups in themselves. * Basic OMAP5 DSS support for DPI and DSI outputs. * Workaround for the problem that GFX overlay's fifo is too small for high resolution scenarios, causing underflows. * Cleanups that remove dependencies to omap platform code.

2012-09-26OMAPDSS: DISPC: Configure overlay-like parameters in dispc_wb_setupArchit Taneja1-0/+13
Create struct omap_dss_writeback_info, this is similar to omap_overlay_info, the major difference is that there is no parameter which describes the input size to writeback, this is because this is always fixed, and decided by the connected overlay or overlay manager. One more difference is that screen_width is renamed to buf_width, to give the value of stride the writeback buffer has. Call dispc_ovl_setup_common() through dispc_wb_setup() to configure overlay-like parameters. The parameters in dispc_ovl_setup_common() which do not hold for writeback are filled passed as zeroes or false, the code takes care of not configuring them as they won't possess the needed overlay caps.

2012-09-26OMAPDSS: OVERLAY: Add position and replication as overlay capsArchit Taneja1-0/+2
Add position and replication as overlay caps, and pass overlay caps as an argument to the corresponding functions. Adding position and replication to overlay caps seems a bit unnecessary, but it allows us to use the corresponding functions for writeback too. These caps will be set for all overlays, but not for writeback. This is done so writeback can reuse dispc_ovl_setup() to the maximum. Signed-off-by: Archit Taneja <archit@ti.com>
2012-09-26OMAPDSS: Remove old way of setting manager and device linksArchit Taneja1-5/+0
Now that an omap_dss_output can be used to link between managers and devices, we can remove the old way of setting manager and device links. This involves removing the device and manager pointers from omap_overlay_manager and omap_dss_device respectively, and removing the set_device/unset_device ops from omap_overlay_manager.

2012-09-26OMAPDSS: Remove manager->device referencesArchit Taneja1-0/+4
With the introduction of output entities, managers will now connect to outputs. Create helper ops for overlays and managers named get_device. This will abstract away the information on how to get the device from an overlay or an overlay manager. The get_device ops currently retrieve the output via a ovl->manager->device reference. This will be later replaced by ovl->manager->output->device references. Signed-off-by: Archit Taneja <archit@ti.com>
2012-09-26OMAPDSS: APPLY: Add manager set/unset output ops for omap_overlay_managerArchit Taneja1-0/+5
Add set_output/unset_output ops for overlay managers, these form links between managers and outputs. Create a function in dss features which tell all the output instances that connect to a manager, use it when a manager tries to set an output. Add a constraint of not unsetting an output when the manager is enabled. Keep the omap_dss_device pointer and set/unset_device ops in overlay_manager for now to not break things. Keep the dss feature function get_supported_displays as it's used in some places. These will be removed later. Signed-off-by: Archit Taneja <archit@ti.com>
2012-09-26OMAPDSS: output: Add set/unset device ops for omap_dss_outputArchit Taneja1-0/+4
An output entity represented by the struct omap_dss_output connects to a omap_dss_device entity. Add functions to set or unset an output's device. This is similar to how managers and devices were connected previously. An output can connect to a device without being connected to a manager. However, the output needs to eventually connect to a manager so that the connected panel can be enabled. Keep the omap_overlay_manager pointer in omap_dss_device for now to prevent breaking things. This will be removed later when outputs are supported completely. Signed-off-by: Archit Taneja <archit@ti.com>
2012-09-26OMAPDSS: outputs: Create a new entity called outputsArchit Taneja1-0/+30
The current OMAPDSS design contains 3 software entities: Overlays, Managers and Devices. These map to pipelines, overlay managers and the panels respectively in hardware. One or more overlays connect to a manager to represent a composition, the manager connects to a device(generally a display) to display the content. The part of DSS hardware which isn't represented by any of the above entities are interfaces/outputs that connect to an overlay manager, i.e blocks like DSI, HDMI, VENC and so on. Currently, an overlay manager directly connects to the display, and the output to which it is actually connected is ignored. The panel driver of the display is responsible of calling output specific functions to configure the output. Adding outputs as a new software entity gives us the following benefits: - Have exact information on the possible connections between managers and outputs: A manager can't connect to each and every output, there only limited hardware links between a manager's video port and some of the outputs. - Remove hacks related to connecting managers and devices: Currently, default links between managers and devices are set in a not so clean way. Matching is done via comparing the device type, and the display types supported by the manager. This isn't sufficient to establish all the possible links between managers, outputs and devices in hardware. - Make panel drivers more generic: The DSS panel drivers currently call interface/output specific functions to configure the hardware IP. When making these calls, the driver isn't actually aware of the underlying output. The output driver extracts information from the panel's omap_dss_device pointer to figure out which interface it is connected to, and then configures the corresponding output block. An example of this is when a DSI panel calls dsi functions, the dsi driver figures out whether the panel is connected to DSI1 or DSI2. This isn't correct, and having output as entities will give the panel driver the exact information on which output to configure. Having outputs also gives the opportunity to make panel drivers generic across different platforms/SoCs, this is achieved as omap specific output calls can be replaced by ops of a particular output type. - Have more complex connections between managers, outputs and devices: OMAPDSS currently doesn't support use cases like 2 outputs connect to a single device. This can be achieved by extending properties of outputs to connect to more managers or devices. - Represent writeback as an output: The writeback pipeline fits well in OMAPDSS as compared to overlays, managers or devices. Add a new struct to represent outputs. An output struct holds pointers to the manager and device structs to which it is connected. Add functions which can register/unregister an output, or look for one. Create an enum which represent each output instance. Signed-off-by: Archit Taneja <archit@ti.com>
2012-09-07OMAPDSS: Use WB fifo for GFX overlayTomi Valkeinen1-0/+1
OMAP4's GFX overlay has smaller fifo than the rest of the overlays (including writeback "overlay"). This seems to be the reason for underflows in some more demanding scenarios. We can avoid the problems by using the WB fifo for GFX overlay, and vice versa. WB usage is not supported yet, but when it will, it should perform just fine with smaller fifo as there are no hard realtime constraints with WB. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-09-07OMAPDSS: DSI: calculate dsi clockTomi Valkeinen1-0/+2
Currently the way to configure clocks related to DSI (both DSI and DISPC clocks) happens via omapdss platform data. The reason for this is that configuring the DSS clocks is a very complex problem, and it's impossible for the SW to know requirements about things like interference. However, for general cases it should be fine to calculate the dividers for clocks in the SW. The calculated clocks are probably not perfect, but should work. This patch adds support to calculate the dividers when using DSI command mode panels. The panel gives the required DDR clock rate and LP clock rate, and the DSI driver configures itself and DISPC accordingly. This patch is somewhat ugly, though. The code does its job by modifying the platform data where the clock dividers would be if the board file gave them. This is not how it's going to be in the future, but allows us to have quite simple patch and keep the backward compatibility. It also allows the developer to still give the exact dividers from the board file when there's need for that, as long as the panel driver does not override them. There are also other areas for improvement. For example, it would be better if the panel driver could ask for a DSI clock in a certain range, as, at least command mode panels, the panel can work fine with many different clock speeds. While the patch is not perfect, it allows us to remove the hardcoded clock dividers from the board file, making it easier to bring up a new panel and to use device tree from omapdss.

2012-09-07OMAPDSS: HDMI: Move GPIO handling to HDMI driverTomi Valkeinen1-0/+2
We currently manage HDMI GPIOs in the board files via platform_enable/disable calls. This won't work with device tree, and in any case the correct place to manage the GPIOs is in the HDMI driver. This patch moves the handling of the GPIOs to the HDMI driver. The GPIO handling is moved to the common hdmi.c file, and this probably needs to be revisited when adding OMAP5 HDMI support to see if the GPIO handling needs to be moved to IP specific files.

2012-08-16OMAPDSS: DSI: Rename dsi_videomode_data to dsi_videomode_timingsArchit Taneja1-2/+2
The struct omap_dss_dsi_videomode_data holds fields which need to be configured for DSI to operate in video mode. Rename the struct to dsi_videomode_timings. One reason to do this is because most of the fields in the struct are timings related. The other reason is to create a generic op for output specific timings. This generic op can be considered as a way to set custom or private timings for the output. In the case of OMAP, DSI and RFBI require some more timings apart from the relgular DISPC timings. The structs omap_dss_videomode_timings and rfbi_timings can be considered as these output specific timings respectively. Signed-off-by: Archit Taneja <archit@ti.com>

A panel driver is expected to call omapdss_sdi_set_datapairs() before enabling the interface. Even though we configure the number of data pairs here, this function would be finally mapped to a generic interface op called set_data_lines.

2012-07-29video: da8xx-fb: configure FIFO threshold to reduce underflow errorsManjunathappa, Prakash1-0/+3
Patch works around the below silicon errata: During LCDC initialization, there is the potential for a FIFO underflow condition to occur. A FIFO underflow condition occurs when the input FIFO is completely empty and the LCDC raster controller logic that drives data to the output pins attempts to fetch data from the FIFO. When a FIFO underflow condition occurs, incorrect data will be driven out on the LCDC data pins. Software should poll the FUF bit field in the LCD_STAT register to check if an error condition has occurred or service the interrupt if FUF_EN is enabled when FUF occurs. If the FUF bit field has been set to 1, this will indicate an underflow condition has occurred and then the software should execute a reset of the LCDC via the LPSC. This problem may occur if the LCDC FIFO threshold size (LCDDMA_CTRL[TH_FIFO_READY]) is left at its default value after reset. Increasing the FIFO threshold size will reduce or eliminate underflows. Setting the threshold size to 256 double words or larger is recommended.

2012-06-29OMAPDSS: DSI: Fix HSYNC, VSYNC and DE polarities between DISPC and DSIArchit Taneja1-3/+0
For DSI operation in videomode, DISPC logic levels for the signals HSYNC, VSYNC and DE need to be specified to DSI via the fields VP_HSYNC_POL, VP_VSYNC_POL and VP_DE_POL in DSI_CTRL registers. This information is completely internal to DSS as logic levels for the above signals hold no meaning on the DSI bus. Hence a DSI panel driver should be totally oblivious of these fields. Fix the logic levels/polarities in the DISPC and DSI registers to a default value. This is done by overriding these fields in omap_video_timings struct filled by the panel driver for DISPC, and use the equivalent default values when programming DSI_CTRL registers. Also, remove the redundant polarity related fields in omap_dss_dsi_videomode_data. Signed-off-by: Archit Taneja <archit@ti.com>

2012-06-29OMAPDSS: Add some new fields to omap_video_timingsArchit Taneja1-0/+22
Some panel timing related fields are contained in omap_panel_config in the form of flags. The fields are: - Hsync logic level - Vsync logic level - Data driven on rising/falling edge of pixel clock - Output enable/Data enable logic level - HSYNC/VSYNC driven on rising/falling edge of pixel clock Out of these parameters, Hsync and Vsync logic levels are a part of the timings in the Xorg modeline configuration. So it makes sense to move the to omap_video_timings. The rest aren't a part of modeline, but it still makes sense to move these since they are related to panel timings. These fields stored in omap_panel_config in dssdev are configured for LCD panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers. Add the above fields in omap_video_timings. Represent their state via new enums. Add these parameters to the omap_video_timings instances in the panel drivers.

The support for LCD3 manager has been added into the manager module. LCD3 panel has registers as DISPC_CONTROL3 and DISPC_CONFIG3 just like those in LCD and LCD2 panels. These registers control the Display Controller (DISPC) module for LCD3 output. The three LCDs support Display Serial Interface (DSI), Remote Frame Buffer Interface (RFBI) and Parallel CMOS Output Interface (DPI). These LCDs can be connected through parallel output interface using DISPC and RFBI or DPI. For serial interface DSS uses DSI. The LCD3 panel, just like LCD and LCD2 panels, has a clock switch in DSS_CTRL register which has been enabled. The clock switch chooses between DSS_CLK and DPLL_DSI1_C_CLK1 as source for LCD3_CLK. New IRQs as DISPC_IRQ_VSYNC3, DISPC_IRQ_FRAMEDONE3, DISPC_IRQ_ACBIAS_COUNT_STAT3 and DISPC_IRQ_SYNC_LOST3 have been added specific to the new manager.

2012-06-29OMAPDSS: Add support for LCD3 channelChandrabhanu Mahapatra1-0/+1
OMAP5 Display Subsystem (DSS) architecture comes with a additional LCD3 channel with its own dedicated overlay manager. The current patch adds LCD3 channel and basic register support for LCD3 channel. It adds register addresses for various Display Controller (DISPC) registers like DISPC_DEFAULT_COLOR, DISPC_TIMING_H, DISPC_DIVISORo, etc. Signed-off-by: Chandrabhanu Mahapatra <cmahapatra@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-06-28OMAPDSS: remove enum omap_dss_overlay_managersTomi Valkeinen1-7/+0
We have two almost the same enums: omap_channel and omap_dss_overlay_managers. omap_channel is used almost everywhere, and omap_channel assigns explicit values to the enum values which are needed for proper operation. omap_dss_overlay_managers is only used in one place, so it's easy to remove it, which is what this patch does.

Omapdss driver changes for 3.5 merge window. Lots of normal development commits, but perhaps most notable changes are: * HDMI rework to properly decouple the HDMI audio part from the HDMI video part. * Restructure omapdss core driver so that it's possible to implement device tree support. This included changing how platform data is passed to the drivers, changing display device registration and improving the panel driver's ability to configure the underlying video output interface. * Basic support for DSI packet interleaving

Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform. Many good cleanups also went into the at91 and omap platforms, as has been the case for a number of releases."
