* OMAP: DSS2: Remove unused opt_clock_availableTomi Valkeinen2011-07-251-2/+0

* OMAP: DSS2: rewrite use of context_loss_countTomi Valkeinen2011-07-251-1/+1
| | | | | | | | | | | | | | | The function to get device's context loss count has changed from omap_pm_get_last_off_on_transaction_id() to omap_pm_get_dev_context_loss_count() Change name of the function pointer in omapdss.h accordingly, and use the term "context loss count" instead of "context id" in the code. Restructure the context loss count functions to handle errors properly, and ensure that context is always considered lost if an error happens. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| * | OMAP: DSS2: Add support for NV12 formatAmber Jain2011-05-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the support for NV12 color format. Configure base address for UV component of NV12 color format. Change the way chroma scaling is handled for YUV formats on OMAP4 by enabling chroma-resampling for video pipeline and hence using FIR2 register set for scaling UV. Changes to _dispc_set_scaling(), because of the reason above, are: - call _dispc_set_scaling_common() to handle scaling for all color formats except for OMAP4 where it only handles scaling for RGB or Y-component - call _dispc_set_scaling_uv() for special handling required for UV component on OMAP4. - dispc_set_scaling_uv() also resets chroma-resampling bit for RGB color modes.

| * | OMAP: DSS2: Pass platform_device as an argument in dsi functionsArchit Taneja2011-05-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DSI interface is represented as a platform device, using the DSI platform driver(dsi.c). The current DSI driver design is capable of running only one instance of a DSI device. On OMAP4, there are 2 very similar DSI modules which can be represented as instances of "omapdss_dsi" platform device. Add member "module" in "dssdev.phy.dsi" that tells us which DSI module's lanes the panel is connected to. Modify dsi.c functions to take the device's platform_device struct pointer, provide functions dsi_get_dsidev_from_dssdev() and dsi_get_dsidev_from_id() take the panel's omap_dss_device and module number respectively, and return the platform_device pointer. Currently, the dsi struct is declared globally and is accessed when dsi data is needed. The new pdev argument will be used later to provide the platform device's dsi related data.

| * | OMAP: DSS2: Taal: Implement ULPS functionalityTomi Valkeinen2011-05-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ULPS is a low power state where the DSI lanes are kept at ground. This patch implements ULPS by having a DSI bus inactivity timer which triggers the entry to ULPS. ULPS exit will happen automatically when the driver needs to do something on the DSI lanes. The ulps_timeout is configurable from board file or via sysfs. Additionally another sysfs file, "ulps", can be used to check the current ULPS state, or to manually enter or exit ULPS.

| * | OMAP: DSS2: DSI: add parameter to enter ulps on disableTomi Valkeinen2011-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add parameter to omapdss_dsi_display_disable() which the panel driver can use to tell if the DSI lanes should be put to ULPS before disabling the interface. This can be used to skip ULPS entry in cases where the panel doesn't care about ULPS state, for example when the panel will be reset, or when the display interface will be enabled again right after the disable. This will speed up the operation considerably in cases where entering ULPS would fail with timeout, and the panel driver isn't even interested in entering ULPS.

| * | OMAP: DSS2: DSI: add option to leave DSI lanes powered onTomi Valkeinen2011-05-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DSI pins are powered by VDDS_DSI. If VDDS_DSI is off, the DSI pins are floating even if they are pinmuxed to, say, safe mode and there's a pull down/up. This patch gives the panel drivers an option to leave the VDDS_DSI power enabled while the DSS itself is turned off. This can be used to keep the DSI lanes in a valid state while DSS is off, if the DSI pins are muxed for pull down (not done in this patch). There will be a slight power consumption increase (~100 uA?) when the VDDS_DSI is left on, but because this option is used when the panel is left on, the regulator consumption is negligible compared to panel power consumption. When the panel is fully turned off the VDDS_DSI is also turned off. As an added bonus this will give us faster start up time when starting up the DSS and the regulator is already enabled.

| | | | | | | | | | | | | | | | | | | | | | | | Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats (bpp = 12, 16, and 24) respectively. When double-buffering both Y planes appear before the C planes (Y-Y-C-C), as opposed to Y-C-Y-C. Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use .bpp to distiguish between the 3 modes. The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and should be set accordingly. .nonstd must be set to 0 for RGB mode. Due to the encoding of YUV data, the framebuffer will clear to green instead of black. In YUV 420 mode, panning is only possible in 2 line increments. Additionally in YUV 420 mode the vertical resolution of the framebuffer must be an even number.

To trace fb_info validity we install a notification callback in the HDMI driver, and the only way for it to get to driver internal data is by using struct sh_mobile_lcdc_chan, therefore it had to be extracted into a separate common header.
