2011-10-31backlight: fix broken regulator API usage in l4f00242t03Mark Brown
The regulator support in the l4f00242t03 is very non-idiomatic. 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.

2011-10-05drivers/video: fsl-diu-fb: only DIU modes 0 and 1 are supportedTimur Tabi
The Freescale DIU video controller supports five video "modes", but only the first two are used by the driver. The other three are special modes that don't make sense for a framebuffer driver. Therefore, there's no point in keeping a global variable that indicates which mode we're supposed to use.

2011-10-05drivers/video: fsl-diu-fb: remove unused panel operating mode supportTimur Tabi

2011-10-05drivers/video: fsl-diu-fb: use an enum for the AOI indexTimur Tabi
Each of the five AOIs created by the DIU driver has a special purpose, and they're not treated equally. It makes sense to identify them with an enum instead of a hard-coded number. Since the 'index' is now an enum, it can only contain allowed values, so there's no need to check for an invalid value. This simplifies some other code, such as fsl_diu_disable_panel(), which no longer needs to return an error code.

This mode was originally intended only for the AOIs (overlays) used on planes two and three, but with real margin data, it can now be used as an actual video mode.

2011-10-05drivers/video: fsl-diu-fb: remove broken screen blanking supportTimur Tabi
The function which is supposed to provide screen blanking support doesn't actually do anything, so the framebuffer layer thinks the screen has been blanked when it really isn't. Remove the code completely for now. A side-effect of this change is that the framebuffer console blanking now works correctly. Presumably this is because the console now receives -EINVAL instead of '0' when it asks the driver to blank the screen, so the console does it manually now. A signficant refactoring of the driver is planned, and proper hardware blanking support will added afterwards.

Move several macros and structures from the Freescale DIU driver's header file into the source file, because they're only used by that file. Also delete a few unused macros. The diu and diu_ad structures cannot be moved because they're being used by the MPC5121 platform file.

2011-10-05drivers/video: fsl-diu-fb: fix some ioctlsTimur Tabi
Use the _IOx macros to define the ioctl commands, instead of hard-coded numbers. Unfortunately, the original definitions of MFB_SET_PIXFMT and MFB_GET_PIXFMT used the wrong value for the size, so these macros have new values now. To avoid breaking binary compatibility with older applications, we retain support for the original values, but the driver displays a warning message if they're used. Also remove the FBIOGET_GWINFO and FBIOPUT_GWINFO ioctls. FBIOPUT_GWINFO was never implemented, and FBIOGET_GWINFO was never used by any application.

2011-10-03OMAPDSS/OMAP_VOUT: Fix incorrect OMAP3-alpha compatibility settingArchit Taneja
On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. 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.

2011-10-03video/omap: fix build dependenciesArnd Bergmann
Four of the LCD panel drivers depend on the backlight class, so add the dependency in Kconfig. Selecting the BACKLIGHT_CLASS_DEVICE symbol does not generally work since it has other dependencies.

2011-09-30OMAPDSS: remove vaddr from overlay infoTomi Valkeinen
overlay_info struct, used to configure overlays, currently includes both physical and virtual addresses for the pixels. The vaddr was added to support more exotic configurations where CPU would be used to update a display, but it is not currently used and there has been no interest in the feature. 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>

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>
