2011-12-02OMAPDSS: APPLY: move channel-field to extra_info setTomi Valkeinen
Setting overlay's output channel is currently handled at the same time as other overlay attributes. This is not right, as the normal attributes should only affect one overlay and manager, but changing the channel affects two managers. This patch moves the channel field into the "extra_info" set, handled together with enabled-status. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-12-02OMAPDSS: APPLY: rewrite overlay enable/disableTomi Valkeinen
Overlays are currently enabled and disabled with a boolean in the struct omap_overlay_info. The overlay info is set with ovl->set_overlay_info(), and made into use with mgr->apply(). This doesn't work properly, as the enable/disable status may affect also other overlays, for example when using fifo-merge. Thus the enabling and disabling of the overlay needs to be done outside the normal overlay configuration. This patch achieves that by doing the following things: 1) Add function pointers to struct omap_overlay: enable(), disable() and is_enabled(). These are used to do the obvious. The functions may block. 2) Move the "enabled" field from struct omap_overlay to ovl_priv_data. 3) Add a new route for settings to be applied to the HW, called "extra_info". The status of the normal info and extra_info are tracked separately. The point here is to allow the normal info to be changed and applied in non-blocking matter, whereas the extra_info can only be changed when holding the mutex. This makes it possible to, for example, set the overlay enable flag, apply it, and wait until the HW has taken the flag into use. This is not possible if the enable flag would be in the normal info, as a new value for the flag could be set at any time from the users of omapdss.

2011-12-02OMAPDSS: APPLY: move mgr->enabled to mgr_priv_dataTomi Valkeinen

2011-12-02OMAPDSS: DSI: call mgr_enable/disable for cmd mode displaysTomi Valkeinen
The current code uses dsi_video_mode_enable/disable functions to enable/disable DISPC output for video mode displays. For command mode displays we have no notion in the DISPC side of whether the panel is enabled, except when a dss_mgr_start_update() call is made. However, to properly maintain the DISPC state in apply.c, we need to know if a manager used for a manual update display is currently in use. This patch achieves that by changing dsi_video_mode_enable/disable to dsi_enable/disable_video_output, which is called by both video and command mode displays. For video mode displays it starts the actual pixel stream, as it did before. For command mode displays it doesn't do anything else than mark that the manager is currently in use.

2011-12-02OMAPDSS: store overlays in a list for each managerTomi Valkeinen
Current way of handling overlay-manager links is a bit strange: each manager has a static array, containing pointers to all the overlays (even those used by other managers). The overlays contain a pointer to the manager being used. This patch makes the system a bit saner: each manager has a linked list of overlays, and only the overlays linked to that manager are in the list.

2011-12-02OMAPDSS: hide manager's enable/disable()Tomi Valkeinen
omap_overlay_manager struct contains enable() and disable() functions. However, these are only meant to be used from inside omapdss, and thus it's bad to expose the functions. This patch adds dss_mgr_enable() and dss_mgr_disable() functions to apply.c, which handle enabling and disabling the output. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-12-02OMAPDSS: remove partial update from DSITomi Valkeinen
Partial update for manual update displays has never worked quite well: * The HW has limitations on the update area, and the x and width need to be even. * Showing a part of a scaled overlay causes artifacts. * Makes the management of dispc very complex Considering the above points and the fact that partial update is not used anywhere, this and the following patches remove the partial update support. This will greatly simplify the following re-write of the apply mechanism to get proper locking and additional features like fifo-merge. This patch removes the partial update from the dsi.c.

2011-11-08ARM: OMAP: HWMOD: Unify DSS resets for OMAPsTomi Valkeinen
This patch adds a custom DSS reset function used on OMAPs from OMAP2 forward. The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.

2011-10-03OMAPDSS: DISPC: zorder support for DSS overlaysArchit Taneja
Add zorder support on OMAP4, this feature allows deciding the visibility order of the overlays based on the zorder value provided as an overlay info parameter or a sysfs attribute of the overlay object. Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER if the caps are not available. Ensure that all overlays that are enabled and connected to the same manager have different zorders. Swapping zorders of 2 enabled overlays currently requires disabling one of the overlays.

2011-10-03OMAPDSS/OMAP_VOUT: Fix incorrect OMAP3-alpha compatibility settingArchit Taneja
On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. On OMAP4, alpha blending is always enabled by default, if the above bits are set, we switch to an OMAP3 compatibility mode where the zorder values in the pipeline attribute registers are ignored and a fixed priority is configured. Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4 alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is expected to check for the ZORDER cap, if an overlay doesn't have this cap, the user is expected to set the parameter partial_alpha_enabled. If the overlay has ZORDER cap, the DSS2 user can assume that alpha blending is already enabled. Don't support OMAP3 compatibility mode for now. Trying to read/write to alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits. Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha blending or not. Replace this with checks for VIDEO1 pipeline.

2011-09-30OMAPDSS: remove vaddr from overlay infoTomi Valkeinen
overlay_info struct, used to configure overlays, currently includes both physical and virtual addresses for the pixels. The vaddr was added to support more exotic configurations where CPU would be used to update a display, but it is not currently used and there has been no interest in the feature. Using CPU to update a screen is also less interesting now that OMAP4 has two LCD outputs. This patch removes the vaddr field, and modifies the users of omapdss accordingly. This makes the use of omapdss a bit simpler, as the user doesn't need to think if it needs to give the vaddr. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-09-30OMAPDSS: Add N800 panel driverTomi Valkeinen
This is a driver for N800's display, ported from the old omapfb. This is a slightly lighter version of the driver as not all features of the old driver can be ported without big changes to DSS2, and also because some of the HW features used in the old driver are unclear (e.g. the power management part). That said, the new driver works fine for basic use. Architecturally the driver is not as neat as it could be. N800's display HW consists of a display buffer chip and a panel, and ideally they would be represented by separate, independent drivers. This is not currently possible, and this driver contains both buffer chip and panel driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-09-30OMAPDSS: Taal: remove external backlight supportTomi Valkeinen
Taal panel driver supports two kinds of backlight control: 1) using DSI commands sent to the panel to control the backlight, 2) calling function pointers going to the board file to control the backlight. The second option is a bit hacky, and will no longer be needed when the PWM driver supports the backlight features. After that we can use the standard PWM backlight driver. This patch removes the second backlight control mechanism, and adds a boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the board file can use to inform whether the panel driver should use DSI commands to control the backlight.

regn divider is currently programmed to the registers without change, but when calculating clock frequencies it is used as regn+1. To make this similar to how DSI handles the dividers this patch changes the regn value to be used as such for calculations, but the value programmed to registers is regn-1. This simplifies the clock frequency calculations, makes it similar to DSI, and also allows us to use regn value 0 as undefined.

It is ok to remove the support, because: - No one has used the feature. - Display update without DISPC is very slow, so it is debatable if the update would even be usable. - Removal cleans up code. - If such a feature is needed later, it is better implemented outside omapdss driver.

2011-09-30OMAP: DSS2: Handle manager change in applyTomi Valkeinen
Currently when changing the manager of an overlay, set_manager() directly calls dispc to set the overlay's destination. Change this to be more in line with other overlay configurations, and this will also remove the need to have dispc clocks enabled when calling set_manager(). A new field is added to overlay struct, "manager_changed". This is similar to "display_changed" field in manager struct, and is used to inform apply that the manager has changed and thus write to the registers is needed.
