* viafb: correct sync polarity for OLPC DCONDaniel Drake2011-11-221-2/+2
| | | | | | | | | | | | | | | | | | | While the OLPC display appears to be able to handle either positive or negative sync, the Display Controller only recognises positive sync. This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and fixes a recent regression where the XO-1.5 DCON could no longer be frozen. Thanks to Florian Tobias Schandinat for helping identify the fix. Test case: from a vt, echo 1 > /sys/devices/platform/dcon/freeze should cause the current screen contents to freeze, rather than garbage being displayed.

| * OMAPDSS: DISPC: skip scaling calculations when not scalingTomi Valkeinen2011-11-181-6/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code calculates scaling factors for video overlays even when the overlays are not scaled. Change the code to skip calculations when not scaling. This optimizes the code a bit, but also fixes a problem when configuring an overlay for a disabled display: if the display is disabled we don't necessarily know the pixel clock used when the display is enabled, and in some cases (like HDMI) the pixel clock is set to zero until a proper video mode is set later. A wrong pixel clock will mess up the scaling calculations, causing an error like: omapdss DISPC error: failed to set up scaling, required fclk rate = 0 Hz, current fclk rate = 170666666 Hz A proper fix would be to check later whether the clocks are enough for the scaling, at the point when the overlay or display is actually enabled, but this patch removes the problem for now.

Rather than requesting the regulators based on the device name and the supply names used by the device the driver requires boards to pass system specific supply names around through platform data. The driver also conditionally requests the regulators based on this platform data, adding unneeded conditional code to the driver. Fix this by removing the platform data and converting to the standard idiom, also updating all in tree users of the driver. As no datasheet appears to be available for the LCD I'm guessing the names for the supplies based on the existing users and I've no ability to do anything more than compile test. The use of regulator_set_voltage() in the driver is also problematic, since fixed voltages are required the expectation would be that the voltages would be fixed in the constraints set by the machines rather than manually configured by the driver, but is less problematic.

On OMAP4, alpha blending is always enabled by default, if the above bits are set, we switch to an OMAP3 compatibility mode where the zorder values in the pipeline attribute registers are ignored and a fixed priority is configured. Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4 alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is expected to check for the ZORDER cap, if an overlay doesn't have this cap, the user is expected to set the parameter partial_alpha_enabled. If the overlay has ZORDER cap, the DSS2 user can assume that alpha blending is already enabled. Don't support OMAP3 compatibility mode for now. Trying to read/write to alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits. Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha blending or not. Replace this with checks for VIDEO1 pipeline.

Using CPU to update a screen is also less interesting now that OMAP4 has two LCD outputs. This patch removes the vaddr field, and modifies the users of omapdss accordingly. This makes the use of omapdss a bit simpler, as the user doesn't need to think if it needs to give the vaddr. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

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>

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.

This function returns the correct pixel clock for LCD and LCD2 managers, but not for TV manager. Extend this function so that it gets the correct pixel clock for TV manager. This also prevents the crash we get when we try to scale overlays connected to TV manager. The current code leads to a BUG() being executed if we call dispc_mgr_pclk_rate() for the TV manager.
