* OMAP: DSS2: DSI: Add DSI pad muxing supportTomi Valkeinen2011-05-111-0/+1
| | | | | | | | Add dsi_mux_pads function pointer to omap_dss_board_info, and use the function pointer in DSI code to configure the DSI pads either to normal DSI operation, or to pull down when in ULPS. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | The SH-Mobile HDMI driver runs in several contexts: ISR, delayed work-queue, task context, when called from the sh_mobile_lcdc framebuffer driver. This creates ample race possibilities. Even though most these races are purely theoretical, it is better to close them. 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.

* broadsheetfb: support storing waveformJaya Kumar2010-03-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds waveform storing capability to broadsheetfb. It uses the firmware class to retrieve the waveform, and the request to initiate the waveform storing is done via a driver sysfs entry, loadstore_waveform. Broadsheet is a framebuffer device. It is slightly different from a typical framebuffer controller that drives a normal TFT-LCD display. Most E-Ink display panels require a waveform in order to function. That is, in order to drive the state of a pixel to black, gray, or white, a specific waveform is utilized. Basically, that waveform represents the specific E-field wiggling needed to get the pixel to its optimal state given current temperature, and its previous state. TN/IPS-LCDs use a similar concept but the driving waveform is sufficiently simple that it is internalized in the TFT source/gate driver. These E-Ink waveforms are specific to a production batch. That is, a batch of display films are produced, then they get characterized and a waveform is generated for that batch. Broadsheet, typically, is attached to its private SPI flash which is then flashed with this waveform. Users won't be able to see the waveform and typically won't ever need to know about it. If however, the display panel attached to broadsheet is changed out, then they will need to update their waveform. That would typically be done at a factory or repair facility rather than by a user.

* broadsheetfb: add multiple panel type supportJaya Kumar2010-03-121-0/+1
| | | | | | | | | | | | Update broadsheetfb to add support for multiple panel types. The 3.7" and 6" are known to work but the 9.7" is untested due to lack of hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a ->start_transfer() callback to the driver sh_mobile_lcdcfb.c. The callback is used to program the LCDC panel in the case of one-shot mode. Needed by the LCD controller used on the KFR2R09 board.
