* OMAPDSS: add __init & __exitTomi Valkeinen2012-05-11
| | | | | | | Now that we are using platform_driver_probe() we can add __inits and __exits all around. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | Now that the core.c doesn't fail if output driver's init fails, we can change the uses of platform_driver_register to platform_driver_probe. This will allow us to use __init in the following patches. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: move the creation of debugfs filesTomi Valkeinen2012-05-11
| | | | | | | | Instead of having an ugly #ifdef mess in the core.c for creating debugfs files, add a dss_debugfs_create_file() function that the dss drivers can use to create the debugfs files. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | Now that the omapdss_core device is the parent for all other dss devices, we don't need to use the dss_runtime_get/put anymore. Instead, enabling omapdss_core will happen automatically when a child device is enabled. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: create DPI & SDI driversTomi Valkeinen2012-05-11
| | | | | | | | | | | | | | | We currently have separate device/driver for each DSS HW module. The DPI and SDI outputs are more or less parts of the DSS or DISPC hardware modules, but in SW it makes sense to represent them as device/driver pairs similarly to all the other outputs. This also makes sense for device tree, as each node under dss will be a platform device, and handling DPI & SDI somehow differently than the rest would just make the code more complex. This patch modifies the dpi.c and sdi.c to create drivers for the platform devices. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: use platform_driver_probe for core/dispc/dssTomi Valkeinen2012-05-11

* OMAPDSS: clean up the omapdss platform data messTomi Valkeinen2012-05-11
| | | | | | | | | | | | | | | | | 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.

* OMAPDSS: DSI: use dsi_get_dsidev_id(dsidev) instead of dsidev->idTomi Valkeinen2012-05-11
| | | | | | | | The DSI driver uses dsi_get_dsidev_id() to get the ID number for the DSI instance. However, there were a few places where dsidev->id was used instead of the function. Fix those places to use the function. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAPFB: fix parsing of vram parameterTomi Valkeinen2012-05-11
| | | | | | | | | | | | | omapfb_parse_vram_param()'s check for end pointer returned from simple_strtoul() is wrong, causing the code to bug if the second or later vram parameters are non-parseable, for example "omapfb.vram=0:2M,:5M". However, even in that case the code will most likely bail out with -EINVAL in the following checks, so the bug is probably not a fatal one.

* OMAPDSS: OMAPFB: always allow to configure overlayGrazvydas Ignotas2012-05-11
| | | | | | | | | | | | | Currently when multiple overlays are active, OMAPFB_SETUP_PLANE fails. Instead of failing, allow it to configure the first overlay as if there was only one overlay, the remaining ones will have to be configured in other ways (sysfs). This allows overlay-controlling programs (like video players) to function properly when framebuffer is cloned to another display (like TV).

* OMAPDSS: VENC: allow switching venc output type at runtimeGrazvydas Ignotas2012-05-11
| | | | | | | | | | | | | | VENC output type (composite/svideo) doesn't have to be fixed by board wiring, it is possible to also provide composite signal through svideo luminance connector (software enabled), which is what pandora does. Having to recompile the kernel for users who have TV connector types that don't match default board setting is very inconvenient, especially for users of a consumer device, so add support for switching VENC output type at runtime over a new sysfs file output_type.

| * OMAPDSS: DSI: implement generic DSI pin configTomi Valkeinen2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for device tree, this patch changes how the DSI pins are configured. 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.

* | OMAPDSS: DISPC: Remove usage of dispc_mgr_get_device()Archit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | The functions calc_fclk_five_taps() and check_horiz_timing_omap3() use the function dispc_mgr_get_device() to get the omap_dss_device pointer to which the manager is connected, the width of the panel is derived from that. The manager's timing is stored in it's private data in APPLY. This contains the latest timings applied to the manager. Pass these timings to dispc_ovl_setup() and use them in the above functions.

* | OMAPDSS: DPI/HDMI: Apply manager timings even if panel is disabledArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DPI and HDMI interfaces use their 'set_timing' functions to take in a new set of timings. If the panel is disabled, they do not disable and re-enable the interface. Currently, the manager timings are applied in hdmi_power_on() and dpi_set_mode() respectively, these are not called by set_timings if the panel is disabled. When checking overlay and manager data, the DSS driver uses the last applied manager timings, and not the timings held by omap_dss_device struct. Hence, there is a need to apply the new manager timings even if the panel is disabled. Apply the manager timings if the panel is disabled. Eventually, there should be one common place where the timings are applied independent of the state of the panel. Signed-off-by: Archit Taneja <archit@ti.com>
* | OMAPDSS: APPLY: Remove display dependency from overlay and manager checksArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | In order to check the validity of overlay and manager info, there was a need to use the omap_dss_device struct to get the panel resolution. The manager's private data in APPLY now contains the manager timings. Hence, we don't need to rely on the display resolution any more. Pass the manager's timings in private data to dss_mgr_check(). Remove the need to pass omap_dss_device structs in the functions which check for the validity of overlay and manager parameters. Signed-off-by: Archit Taneja <archit@ti.com>
* | OMAPDSS: APPLY: Don't check manager settings if it is disabledArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If a manager is disabled, there is no guarantee at any point in time that all it's parameters are configured. There is always a chance that some more parameters are yet to be configured by a user of DSS, or by DSS itself. However, when the manager is enabled, we can be certain that all the parameters have been configured, as we can't enable a manager with an incomplete configuration. Therefore, if a manager is disabled, don't check for the validity of it's parameters or the parameters of the overlays connected to it. Only check once it is enabled. Add a check in dss_check_settings_low() to achieve the same. Signed-off-by: Archit Taneja <archit@ti.com>
* | OMAPDSS: MANAGER: Create a function to check manager timingsArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a function dss_mgr_check_timings() which wraps around the function dispc_mgr_timings_ok(). This is mainly a clean up to hide dispc functions from interface drivers. dss_mgr_check_timings() is added in the function dss_mgr_check(), it currently takes the timings maintained in the omap_dss_device struct. This would be later replaced by the timings stored in the manager's private data. Make dss_mgr_check_timings() and dispc_mgr_timings_ok() take a const omap_video_timings pointer since these functions just check the timings. Signed-off-by: Archit Taneja <archit@ti.com>
* | OMAPDSS: Apply manager timings instead of direct DISPC writesArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | Replace the function dispc_mgr_set_timings() with dss_mgr_set_timings() in the interface drivers. The latter function ensures that the timing related DISPC registers are configured according to the shadow register programming model. Remove the call to dispc_mgr_go() in dpi_set_timings() as the manager's go bit is set by dss_mgr_set_timings(). Signed-off-by: Archit Taneja <archit@ti.com>
* | OMAPDSS: APPLY: Add manager timings as extra_info in private dataArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DISPC manager size and DISPC manager blanking parameters(for LCD managers) follow the shadow register programming model. Currently, they are programmed directly by the interface drivers. To configure manager timings using APPLY, there is a need to introduce extra info flags for managers, similar to what is done for overlays. This is needed because timings aren't a part of overlay_manager_info struct configured by a user of DSS, they are configured internally by the interface or panel drivers. Add dirty and shadow_dirty extra_info flags for managers, update these flags at the appropriate places. Rewrite the function extra_info_update_ongoing() slightly as checking for manager's extra_info flags can simplify the code a bit. Create function dss_mgr_set_timings() which applies the new manager timings to extra_info. Signed-off-by: Archit Taneja <archit@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function ti_hdmi_4xxx_core_dump has some bugs, the following mention the bugs and the solutions: - The macros DUMPCORE and DUMPCOREAV in ti_hdmi_4xxx_core_dump() use hdmi_pll_base() for the offsets needed to calculate register addresses, use functions hdmi_core_sys_base() amd hdmi_av_base() to calculate the correct offsets for CORE_SYS and CORE_AV registers. - Many of the CORE_AV registers use the DUMPCORE macro, and hence the register addresses are calculated incorrectly. Rename the current DUMPCOREAV macro as DUMPCOREAV2 as it takes 2 arguments to dump indexed CORE_AV registers, create a new macro called DUMPCOREAV which is now used for dumping non-indexed CORE_AV registers.

* | OMAPDSS: DISPC: Handle synclost errors in OMAP3Chandrabhanu Mahapatra2012-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In OMAP3 DISPC video overlays suffer from some undocumented horizontal position and timing related limitations leading to SYNCLOST errors. Whenever the image window is moved towards the right of the screen SYNCLOST errors become frequent. Checks have been implemented to see that DISPC driver rejects configuration exceeding above limitations. This code was successfully tested on OMAP3. This code is written based on code written by Ville Syrjälä <ville.syrjala@nokia.com> in Linux OMAP kernel.

* | OMAPDSS: DISPC: Enable predecimationChandrabhanu Mahapatra2012-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In OMAP3 and OMAP4, the DISPC Scaler can downscale an image up to 4 times, and up to 2 times in OMAP2. However, with predecimation, the image can be reduced to 16 times by fetching only the necessary pixels in memory. Then this predecimated image can be downscaled further by the DISPC scaler. The pipeline is configured to use a burst of size 8 * 128 bits which consists of 8 mini bursts of 16 bytes each. So, horizontal predecimation more than 16 can lead to complete discarding of such mini bursts. L3 interconnect may handover the bus to some other initiator and inturn delay the fetching of pixels leading to underflows. So, maximum predecimation limit is fixed at 16. Based on the downscaling required, a prior calculation of predecimation values for width and height of an image is done. Since, Predecimation reduces quality of an image higher priorty is given to DISPC Scaler for downscaling. This code was successfully tested on OMAP2, OMAP3 and OMAP4. Horizontal and vertical predecimation worked fine except for some synclost errors due to undocumented errata in OMAP3 which are fixed later and skewed images were seen on OMAP2 and OMAP3 during horizontal predecimation which will be addressed in the future patches. This code is based on code written by Lajos Molnar <lajos@ti.com> who had added predecimation support for NV12/YUV/rotated/SDMA buffers.

Use a common function called dispc_mgr_set_timings() which sets timings for both type of managers. We finally want the interface drivers to use an overlay manager function to configure it's timings, having a common DISPC function would make things cleaner. For LCD managers, dispc_mgr_set_timings() sets LCD size and blanking values, for TV manager, it sets only the TV size since blanking values don't exist for TV.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since any power on stabilisation delay for the supply itself should be taken care of transparently by the regulator API when the regulator is enabled the additional delay that the TPO-TD03MTEA1 driver adds after that returned should be due to the requirements of the device itself rather than the supply (the delay is also suspicously long for one for a regulator to ramp). Correct the comment to avoid misleading people taking this code as a reference.

| | | | | | | | | | | | | | | | | | | | It is possible for regulator_enable() to fail and if it does fail that's generally a bad sign for anything we try to do with the hardware afterwards so check for and immediately return an error if regulator_enable() fails.
