19 | * History: | |
20 | * 20-APR-2006 Khasim Modified VRFB based Rotation, | |
21 | * The image data is always read from 0 degree | |
22 | * view and written | |
23 | * to the virtual space of desired rotation angle | |
24 | * 4-DEC-2006 Jian Changed to support better memory management | |
25 | * | |
26 | * 17-Nov-2008 Hardik Changed driver to use video_ioctl2 | |
27 | * | |
28 | * 23-Feb-2010 Vaibhav H Modified to use new DSS2 interface | |
