2009-10-19DSS2: Fix omapfb framebuffer nameTomi Valkeinen
After clearing the fix and var screeninfos fix.id should be reset to the proper value. Move the relevant memset() and strncpy() calls into a helper function which does the right thing. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Conflicts: drivers/video/omap2/omapfb/omapfb-main.c
2009-10-19DSS2: Correctly determine if an interlaced display is usedTomi Valkeinen
When applying the settings to all the overlays ilace is initialzed to 0 in the beginning and then changed to 1 when the first overlay directed to an interlaced display is found. If there are more overlays after that one which are not directed to an interlaced display the code would still pass ilace=1 to the the dispc code which would halve the output height of the overlay. Fix the problem by correctly setting ilace for each overlay. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Conflicts: drivers/video/omap2/dss/manager.c
2009-10-19DSS2: Fix bottom field initial starting lineVille Syrjälä
When downscaling the bottom field offset may be several source lines. Unfortunately the registers for the initial accumulator value will only hold the fractional part of of that offset so the integer part must be added to the bottom field base address. The TV-out quality is significantly improved as a result. Additionally this fixes the bottom field offset with DMA rotation and mirroring enabled as it was previously miscalculated.

2009-10-19DSS2: isolate the SDI pads when SDI is disabledTomi Valkeinen
When SDI is disabled there is still ~1.6mA drain through the VSDI_CSI regulator. This seems to be internal to the SDI module, since even disconnecting the LCD panel doesn't get rid of the drain. Also disabling/resetting the SDI or the DSS module doesn't help. The only solution is to configure the SDI pads to safe mode with pull up resistors enabled on them when SDI gets disabled. Bootloader / platform code is still responsible for setting up the muxing, so in the driver check if all required pads are in SDI mode or all of them are in non-configured state.

Use better model for handling DSS devices and drivers. Remove omap_display, omap_ctrl and omap_panel structs, and add omap_dss_device and omap_dss_driver. DSS devices are added to DSS bus. The commit changes almost every part of DSS2, even if actual functionality should be changed only in few parts. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

2009-10-19DSS2: DSI: Implement DSI bus lockTomi Valkeinen
DSI bus lock protects the DSI bus. Normally dsi driver acquires the lock, but if display drivers have their own workqueues, or similar, they need to acquire the bus lock before sending data. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

2009-10-19DSS2: Reset WSS data only when changing TV standardVille Syrjälä
Do not reset the the WSS data every time the display is enabled. Only reset it when the TV standard changes since PAL and NTSC use different WSS data layouts. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com>

2009-10-19DSS2: support for querying the supported overlay color modesMayuresh Janorkar
Adds an IOCTL through which an application can iterate through the color modes supported by an overlay. Instead of a simple mode ID this will give the parameters needed to setup the FB, as this is what the application will do anyway. Signed-off-by: Mayuresh Janorkar <mayur@ti.com>
2009-10-19DSS2: Enable replication logic featureTomi Valkeinen

2009-10-19DSS2: Fix PAL/NTSC timingsVille Syrjälä
Fix the PAL/NTSC video timings. Only some of these values are actually specified for digital video, the rest were calculated based on the the analog timings. The analog timings differ from the digital timings anyway but these should be close to the truth. These values aren't actually needed by the VENC but it doesn't hurt to make them a bit more accurate.

2009-10-19DSS2: Allow independent rotation for each planeVille Syrjälä
Allow overlays attached to the same framebuffer to have different rotation settings. A new sysfs file overlays_rotate can be used to configure the rotation settings for each overlay. The total rotation for a single overlay is now '(var.rotate + overlays_rotate) % 4'. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com>
2009-10-19DSS2: Do not swap xres/yres or change rotation in check_fb_var()Ville Syrjälä
Do not to change the actual rotation setting in check_fb_var() and also remove the xres/yres swap from the same place. Applications must now specify var.xres and var.yres in framebuffer coordinates. Eg. if you have a 480x800 framebuffer and want it rotated cw/ccw to a 800x480 display xres must be 480 and yres must be 800. So the application doesn't have to know if it's dealing with a 480x800 unrotated display or a 800x480 rotated display. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com>
2009-10-19DSS2: DSI: Fix LP clockTomi Valkeinen

2009-10-19DSS2: VRFB: don't WARN when releasing inactive ctxImre Deak

2009-10-19VRFB: add suspend/resume functionalityImre Deak
At the moment the VRFB context is restored at each core power domain OFF->ON transition. This is not optimal since the VRFB might be unused temporarily for example when the screen is blanked. Add a suspend / resume function to mark these unused periods during which we'll avoid thea the context restore. Use atomic bitops for ctx_map for consistency.

2009-10-19DSS2: fix the usage of get_last_off_on_transaction_idImre Deak
The function returns int not unsigned since it can fail. Handle the failing case as if the context had been lost. So now: 1. No get_last_off_on_transaction_id func in platform data-> never restore the context 2. Return val < 0 -> force the restore 3. Return val >= 0 do the restore only if the counter has changed.

2009-10-19DSS2: VRFB: save / restore contextImre Deak
The VRFB is part of the SMS and supplied by the core power domain; do the context saving while VRFB is configured and restore it along with the rest of the domain context. This patch only implements the restore functionality, but not the actual call to the restore. That belongs to PM functionality.
2009-10-19DSS2: Avoid div by zero when calculating required fclkVille Syrjälä
When calculating the required fclk rate for five tap filtering if the display width and output width are equal div by zero could occur. The TRM doesn't actually specify how this case should be handled but for now just skip the calculation which would trigger the div by zero. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com>
