* video: da8xx-fb: configure FIFO threshold to reduce underflow errorsManjunathappa, Prakash2012-07-291-0/+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.

| * OMAPDSS: DSI: Fix HSYNC, VSYNC and DE polarities between DISPC and DSIArchit Taneja2012-06-291-3/+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>
| * OMAPDSS: Add interlace parameter to omap_video_timingsArchit Taneja2012-06-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | Add a parameter called interlace which tells whether the timings are in interlaced or progressive mode. This aligns the omap_video_timings struct with the Xorg modeline configuration. It also removes the hack needed to write to divide the manager height by 2 if the connected interface is VENC.

| | | | | | | | | | | | | | | | | | | | | | omap_panel_config contains fields which are finally written to DISPC_POL_FREQo registers. These are now held by omap_video_timings and are set when the manager timings are applied. Remove the omap_panel_config enum, and remove all it's references from panel or interface drivers.

| * OMAPDSS: Add some new fields to omap_video_timingsArchit Taneja2012-06-291-0/+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. Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in omap_panel_config for now. The struct will be removed later. Signed-off-by: Archit Taneja <archit@ti.com>

| * OMAPDSS: Add LCD3 overlay manager and Clock and IRQ supportChandrabhanu Mahapatra2012-06-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * OMAPDSS: DISPC: Support rotation through TILERChandrabhanu Mahapatra2012-05-221-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TILER is a block in OMAP4's DMM which lets DSS fetch frames in a rotated manner. Physical memory can be mapped to a portion of OMAP's system address space called TILER address space. The TILER address space is split into 8 views. Each view represents a rotated or mirrored form of the mapped physical memory. When a DISPC overlay's base address is programmed to one of these views, the TILER fetches the pixels according to the orientation of the view. A view is further split into 4 containers, each container holds elements of a particular size. Rotation can be achieved at the granularity of elements in the container. For more information on TILER, refer to the Memory Subsytem section in OMAP4 TRM. Rotation type TILER has been added which is used to exploit the capabilities of these 8 views for performing various rotations. When fetching from addresses mapped to TILER space, the DISPC DMA can fetch pixels in either 1D or 2D bursts. The fetch depends on which TILER container we are accessing. Accessing 8, 16 and 32 bit sized containers requires 2D bursts, and page mode sized containers require 1D bursts. The DSS2 user is expected to provide the Tiler address of the view that it is interested in. This is passed to the paddr and p_uv_addr parameters in omap_overlay_info. It is also expected to provide the stride value based on the view's orientation and container type, this should be passed to the screen_width parameter of omap_overlay_info. In calc_tiler_rotation_offset screen_width is used to calculate the required row_inc for DISPC. x_predecim and y_predecim are also used to calculate row_inc and pix_inc thereby adding predecimation support for TILER.

| | * OMAPDSS: Provide an interface for audio supportRicardo Neri2012-05-111-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist several display technologies and standards that support audio as well. Hence, it is relevant to update the DSS device driver to provide an audio interface that may be used by an audio driver or any other driver interested in the functionality. The audio_enable function is intended to prepare the relevant IP for playback (e.g., enabling an audio FIFO, taking in/out of reset some IP, enabling companion chips, etc). It is intended to be called before audio_start. The audio_disable function performs the reverse operation and is intended to be called after audio_stop. While a given DSS device driver may support audio, it is possible that for certain configurations audio is not supported (e.g., an HDMI display using a VESA video timing). The audio_supported function is intended to query whether the current configuration of the display supports audio. The audio_config function is intended to configure all the relevant audio parameters of the display. In order to make the function independent of any specific DSS device driver, a struct omap_dss_audio is defined. Its purpose is to contain all the required parameters for audio configuration. At the moment, such structure contains pointers to IEC-60958 channel status word and CEA-861 audio infoframe structures. This should be enough to support HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958. The omap_dss_audio structure may be extended in the future if required. The audio_enable/disable, audio_config and audio_supported functions could be implemented as functions that may sleep. Hence, they should not be called while holding a spinlock or a readlock. The audio_start/audio_stop function is intended to effectively start/stop audio playback after the configuration has taken place. These functions are designed to be used in an atomic context. Hence, audio_start should return quickly and be called only after all the needed resources for audio playback (audio FIFOs, DMA channels, companion chips, etc) have been enabled to begin data transfers. audio_stop is designed to only stop the audio transfers. The resources used for playback are released using audio_disable. A new enum omap_dss_audio_state is introduced to help the implementations of the interface to keep track of the audio state. The initial state is _DISABLED; then, the state transitions to _CONFIGURED, and then, when it is ready to play audio, to _ENABLED. The state _PLAYING is used when the audio is being rendered.

| | * OMAPDSS: clean up the omapdss platform data messTomi Valkeinen2012-05-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omapdss pdata handling is a mess. This is more evident when trying to use device tree for DSS, as we don't have platform data anymore in that case. This patch cleans the pdata handling by: - Remove struct omap_display_platform_data. It was used just as a wrapper for struct omap_dss_board_info. - Pass the platform data only to omapdss device. The drivers for omap dss hwmods do not need the platform data. This should also work better for DT, as we can create omapdss device programmatically in generic omap boot code, and thus we can pass the pdata to it. - Create dss functions for get_ctx_loss_count and dsi_enable/disable_pads that the dss hwmod drivers can call.

The current configuration method is only doable with board files and the configuration data is OMAP specific. This patch moves the configuration data to the panel's platform data, and the data can easily be given via DT in the future. The configuration data format is also changed to a generic one which should be suitable for all platforms. The new format is an array of pin numbers, where the array items start from clock + and -, then data1 + and -, and so on. For example: { 0, // pin num for clock lane + 1, // pin num for clock lane - 2, // pin num for data1 lane + 3, // pin num for data1 lane - ... } The pin numbers are translated by the DSI driver and used to configure the hardware appropriately.

| |/ | | | | | | | | | | | | | | | | | | The driver for the TFP410 chip should handle the power-down signal of the chip, instead of the current way of handling it in the board files. This patch adds power_down_gpio into the device's platform data, and adds the necessary code in the driver to request and handle the GPIO. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

This makes it safe to include <video/vga.h> in all contexts.

Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts."

* | | fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_infoKuninori Morimoto2012-03-211-0/+1

Current SuperH (like sh73a0) can control all of these clocks by CPG (Clock Pulse Generator). It means we can control it by clock framework only. But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS, and only sh7372 has PHYCTRL::PLLDS. But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was overwrote since the callback timing of clock setting was changed by c2658b70f06108361aa5024798f9c1bf47c73374 (fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()). To solve this issue, this patch adds extra .phyctrl. This patch adds detail explanation for unclear mipi settings and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meram_register(), meram_unregister() and meram_update() operations check that the pointers they get from the caller are not NULL. Those checks can be remove, as the caller already ensures that the pointers are valid. The platform sanity checks can also be removed, as the operations can't be accessed without valid platform data anyway. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The range of reserved ICBs (for instance to be used through UIO), if any, is passed in the platform data reserved_icbs field as a bitmask. The MERAM registration function now returns a pointer to an opaque MERAM object, which is passed to the update and unregistration functions.
