2011-07-22video: mcde: Remove special SDTV watermark levelMarcel Tunnissen
This will remove the special setting for the watermark level in MCDE for SDTV out through AV8100. As a consequence MCDE setup is independent of AV8100 running SDTV or HDMI.

2011-06-24fsl-diu-fb: remove check for pixel clock rangesTimur Tabi
The Freescale DIU framebuffer driver defines two constants, MIN_PIX_CLK and MAX_PIX_CLK, that are supposed to represent the lower and upper limits of the pixel clock. These values, however, are true only for one platform clock rate (533MHz) and only for the MPC8610. So the actual range for the pixel clock is chip-specific, which means the current values are almost always wrong. The chance of an out-of-range pixel clock being used are also remote. Rather than try to detect an out-of-range clock in the DIU driver, we depend on the board-specific pixel clock function (e.g. p1022ds_set_pixel_clock) to clamp the pixel clock to a supported value.

The driver indicates that 1920x1080 is a valid mode (the first mode available, in fact), but proceeds to set the framebuffer size to 1600x1200. The patch corrects what seems to be a logic error, regarding unsetting the FB_MISC_1ST_DETAIL flag, if the first (top/best) mode is invalid. The existing code unset the flag if ANY mode was invalid.

2011-06-22OMAP: DSS2: Taal: Make driver more fault tolerantTomi Valkeinen
If ULPS exit fails, and the following reset fails also, Taal driver was left in state where it thinks DSI is enabled while it really isn't, leading to crash. This patch checks the return value of taal_panel_reset, and if that fails, ulps_enabled is left true, causing the driver to retry ulps exit later. Also the return value of taal_wake_up is checked at taal_disable, and if wake up fails, we'll skip the power_off. This could leave the panel into a not-quite-valid state, but there's nothing we can do about it in that situation. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-06-16OMAP: DSS2: OMAPFB: Implement auto-update modeTomi Valkeinen
Implement auto-update mode for manual-update displays. omapfb driver uses a delayed work to update the display with a constant rate. The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which previously called omapdss but is now handled inside omapfb, and a new sysfs file, "update_mode". The update interval is by default 20 times per second, but can be changed via "auto_update_freq" module parameter. There is also a new module parameter "auto_update", which will make omapfb start manual update displays in auto-update mode. This auto-update mode can be used for testing if the userspace does not support manual update displays properly. However, it is a very inefficient solution, and should be considered more as a hack for testing than something that could be used as a long term solution.
