2012-05-11OMAPDSS: TFP410: pdata rewriteTomi Valkeinen
To ease device tree adaptation in the future, rewrite TFP410 platform data handling to be done inside probe(), so that probe() is the only place where we need to handle the DT/pdata choice. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

Conflicts: drivers/video/omap2/displays/panel-taal.c Merge OMAP DSS related board file changes. The branch will also be merged through linux-omap tree to solve conflicts.
2012-05-09OMAPDSS: DSI: implement generic DSI pin configTomi Valkeinen
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.

2012-04-23OMAPDSS: TPO-TD03MTEA1: Correct comment for power on delayMark Brown
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.

2012-04-23OMAP: DSS2: Remove suspicous and unused TAAL regulator API usageMark Brown
The TAAL driver contains some regulator support which is currently unused (the code is there but the one panel supported by the driver doesn't have any regulators provided). This code mostly looks like an open coded version of the regulator core bulk API. The only additional feature is that a voltage range can be set once when the device is opened, though this is never varied at runtime. The general expectation is that if the device is not actively managing the voltage of the device (eg, doing DVFS) then any configuration will be done using the constraints rather than by drivers, saving them code and ensuring that they work well with systems where the voltage is not configurable. If systems are added needing regulator support this can be added back in, though it should be based on core features rather than open coding things.

2012-02-21OMAPDSS: TPO-TD03MTEA1: fix suspend hangGrazvydas Ignotas
During system suspend, at the time DSS is being suspended, SPI is already suspended and it's clocks are cut. Because of this trying to communicate with the LCD controller results in a deadlock. To fix this, split out LCD programming parts of display enable/disable functions and perform them from SPI PM callbacks instead when system is being suspended. If the display is just being enabled/disabled, do it from DSS callbacks as before. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

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.

2011-09-30OMAPDSS: 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.

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.
