2013-03-12videomode: remove timing_entry_indexTomi Valkeinen
Display timing's fields have minimum, typical and maximum values. These can be accessed by using timing_entry_index enum, and display_timing_get_value() function. There's no real need for this extra complexity. The values can be accessed more easily by just using the min/typ/max fields.

2013-03-12videomode: create enum for videomode's display flagsTomi Valkeinen
Instead of having plain defines for the videomode's flags, add an enum for the flags. This makes the flags clearer to use, as the enum tells which values can be used with the flags field. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Steffen Trumtrar <s.trumtrar@pengutronix.de>
2013-03-12videomode: combine videomode dmt_flags and data_flagsTomi Valkeinen
Both videomode and display_timing contain flags describing the modes. These are stored in dmt_flags and data_flags. There's no need to separate these flags, and having separate fields just makes the flags more difficult to use. This patch combines the fields and renames VESA_DMT_* flags to DISPLAY_FLAGS_*.

2013-01-24video: add display_timing and videomodeSteffen Trumtrar
Add display_timing structure and the according helper functions. This allows the description of a display via its supported timing parameters. Also, add helper functions to convert from display timings to a generic videomode structure. The struct display_timing specifies all needed parameters to describe the signal properties of a display in one mode. This includes - ranges for signals that may have min-, max- and typical values - single integers for signals that can be on, off or are ignored - booleans for signals that are either on or off As a display may support multiple modes like this, a struct display_timings is added, that holds all given struct display_timing pointers and declares the native mode of the display. Although a display may state that a signal can be in a range, it is driven with fixed values that indicate a videomode. Therefore graphic drivers don't need all the information of struct display_timing, but would generate a videomode from the given set of supported signal timings and work with that. The video subsystems all define their own structs that describe a mode and work with that (e.g. fb_videomode or drm_display_mode). To slowly replace all those various structures and allow code reuse across those subsystems, add struct videomode as a generic description. This patch only includes the most basic fields in struct videomode. All missing fields that are needed to have a really generic video mode description can be added at a later stage.
