[PATCH v4 0/9] OMAPDSS: APPLY: Treat overlay manager timings as shadow registers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

An overlay manager's timings (the manager size, and blanking parameters if an
LCD manager) are DISPC shadow registers, and they should hence follow the
correct programming model.

This set makes the timings an extra_info parameter in manager's private data .
The interface drivers now apply the timings in instead of directly writing to
registers.

This change also prevents the need to use display resolution for overlay
checks, hence making some of the APPLY functions less dependent on the display.
Some DISPC functions that needed display width can also use these privately
stored timings.

Changes since v3:

- Remove direct setting of go bit in dpi_set_timings()
- Take some of the patches in "OMAPDSS: Misc fixes and cleanups" and make them a
  part of this series as they are more related.
- Don't have an initial set of manager timings in private data, only check
  manager and overlay parameters once the manager is enabled.

These patches apply over:
