| * OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen2012-01-261-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| * | OMAPDSS: APPLY: rewrite overlay enable/disableTomi Valkeinen2011-12-021-2/+4

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.

| * | OMAPDSS: DSI: call mgr_enable/disable for cmd mode displaysTomi Valkeinen2011-12-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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.

| * ARM: OMAP: HWMOD: Unify DSS resets for OMAPsTomi Valkeinen2011-11-081-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This allows panel driver to configure dsi video_mode specific parameters. - Configure basic DSI video mode timing parameters: HBP, HFP, HSA, VBP, VFP, VSA, TL and VACT. - Configure DSI protocol engine registers for video_mode support. - Introduce functions dsi_video_mode_enable() and dsi_video_mode_disable() which enable/disable video mode for a given virtual channel and a given pixel format type. Things left for later - Add functions to check for errors in video mode timings provided by panel. - Configure timing registers required for command mode interleaving.

| * OMAP: DSS2: Create an enum for DSI pixel formatsArchit Taneja2011-09-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, DSI pixel info is only represented by the pixel size in bits using the pixel_size parameter in omap_dss_device struct's ctrl member. This is not sufficient information for DSI video mode usage, as two of the supported formats(RGB666 loosely packed, and RGB888) have the same pixel container size, but different data_type values for the video mode packet header. Create enum "omap_dss_dsi_pixel_format" which describes the pixel data format the panel is configured for. Create helper function dsi_get_pixel_size() which returns the pixel size of the given pixel format. Modify functions omapdss_default_get_recommended_bpp() and dss_use_replication() to use dsi_get_pixel_size().

| * OMAP: DSS2: DSI: Introduce generic read functionsArchit Taneja2011-09-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce read functions which use generic Processor-to-Peripheral transaction types. These are needed by some devices which may not support corresponding DCS commands. Add function dsi_vc_generic_send_read_request() which can send a short packet with 0, 1 or 2 bytes of request data and the corresponding generic data type. Rename function dsi_vc_dcs_read_rx_fifo() to dsi_vc_read_rx_fifo() and modify it to take the enum "dss_dsi_content_type" as an argument to use either DCS or GENERIC Peripheral-to-Processor transaction types while parsing data read from the device.

| * OMAP: DSS2: DSI: Remove functions dsi_vc_dcs_read_1() and dsi_vc_dcs_read_2()Archit Taneja2011-09-301-4/+0
| | | | | | | | | | | | | | | | | | | | Remove functions dsi_vc_dcs_read_1() and dsi_vc_dcs_read_2(), these are used when the panel is expected to return 1 and 2 bytes respecitvely. This was manily used for debugging purposes. These functions should be implemented in the panel driver if needed.

| * OMAP: DSS2: DSI: Introduce generic write functionsArchit Taneja2011-09-301-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Intoduce enum "dss_dsi_content_type" to differentiate between DCS and generic content types. Introduce short and long packet write functions which use generic Processor-to-Peripheral transaction types. These are needed by some devices which may not support corresponding DCS commands. Create common write functions which allow code reuse between DCS and generic write functions. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Add OMAP_DSS_OVL_CAP_GLOBAL_ALPHA and OMAP_DSS_OVL_CAP_PRE_MULT_ALPHA to overlay capabilities. Use these instead of FEAT_GLOBAL_ALPHA, FEAT_GLOBAL_ALPHA_VID1 and FEAT_PRE_MULT_ALPHA in code. Remove FEAT_GLOBAL_ALPHA_VID1 and FEAT_PRE_MULT_ALPHA which are no longer used. FEAT_GLOBAL_ALPHA is still used to decide if the HW has global alpha register. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Archit Taneja <archit@ti.com>
