[PATCH v3 0/3] V4L/DVB: OMAP_VOUT: Allow omap_vout to build without VRFB

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

 



This lets omap_vout driver build and run without VRFB. It works along the
lines of the following patch series:

OMAP: DSS2: OMAPFB: Allow FB_OMAP2 to build without VRFB
https://patchwork.kernel.org/patch/105371/

Since VRFB is tightly coupled with the omap_vout driver, a handful of vrfb
specific functions have been defined and placed in omap_vout_vrfb.c

A new enum called vout_rotation_type is introduced to differentiate between no
rotation and vrfb rotation. A member rotation_type is introduced in omapvideo_info,
this allows to call vrfb specific functions only if the rotation type is VOUT_ROT_VRFB
When the rotation_type is set to VOUT_ROT_NONE, the S_CTRL ioctl prevents the user setting
a non zero rotation or non zero mirror value.

Archit Taneja (3):
  V4L/DVB: OMAP_VOUT: Move some functions and preprocessor defines from
    omap_vout
  V4L/DVB: OMAP_VOUT: Create a seperate vrfb functions library
  V4L/DVB: OMAP_VOUT: Use rotation_type to choose between vrfb rotation
    and no rotation

Version 3:
 - Introduce a new enum at V4L2 driver level which cleanly differentiates
   between vrfb rotation and no rotation, incorporate comments given for v2
Version 2:
 - Don't try to enable SDRAM rotation , return an error if non zero rotation
   is attempted when rotation_type is set to SDMA rotation.
