[PATCH v4 0/19] Various s3c-fb updates

[Pawel Osciak]

Hello,

This series contains various Samsung framebuffer driver updates.
I believe that it has reached the stage of being ready for merging.

The main highlights of this series are:
- Ben Dook's unification of the plethora of Samsung framebuffer header
files with configuration selection at probe time, machine naming;
- palette setup code moved to the main driver;
- added ability to wait for VSYNC and to pan the display;
- better support for new features found in S5PV210 SoCs, including
  shadow register handling and DMA channel control,
- various small changes,
- a number of bugs has also been fixed.


Changes in v4:
- corrected fb_dealloc_cmap condition on window probe failure
- fixed a race condition in wait for VSYNC ioctl
- removed has_osd_size flag from window variant; osd_size_off != 0
  now implies has_osd_size = 1
- cosmetic changes, as suggested by Ben Dooks, and more comments

Changes in v3:
- new patches:
  * fixing a section mismatch error
  * adding support for DMA channel control (enable/disable) found on S5PV210
  * disabling shadow register updates during set_par

- unified function for disabling register updates
- no need to initialize names for 64xx-type framebuffers (is being set as
  default anyway)
- updated to the new version of Ben's branch
- minor fixes

Changes in v2:
- added SHADOWCON register support found on S3C6410 and S5PC100 for disabling
  shadow register updates
- fixed osd and alpha register handling (different configurations for different
  machines)
