+Subject: [PATCH 23/26] OMAP-Resizer: Basic Resizer refreshed with latest gitorious tree
 
-The Resizer and Previewer driver added to the commit
-from the patch submitted by Sergio on 12 Dec 2008.
+This is same resizer driver patch posted by Sergio onto
+mailing list quite a some time back. This commit refreshes
+the same patch on top of latest gitorious.org tree.
 
-The new WTBU code base and Nokia fixes package doesn't contain
-standalone resizer driver support.
+List of New/Modified files:
+ modified:   drivers/media/video/Kconfig
+ modified:   drivers/media/video/isp/Makefile
+ modified:   drivers/media/video/isp/isp.c
+ modified:   drivers/media/video/isp/ispreg.h
+ new file:   drivers/media/video/isp/omap_resizer.c
+ new file:   include/linux/omap_resizer.h
 
-Following major changes done -
-
-	- Added stand-alone resizer driver support
-	  in isp.c file.
-	- Seperate Kconfig file created
-	- hardware access of resizer module fixed as per new
-	  isp.c
-
-Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com>
+TODO:
+ - Resizer driver needs to be independent from camera and ISP
+ - Custom patches implemented ontop of PSP1.0.2 release
+   to fix some V4L2-buf layer issues.

-This commit contains resizer bug fixes on top of
-    PSP1.0.2 release -
-       - 4096 aligned address constraint
-       - workaround for extra page allocation for page aligned
-         size buffers
+V4L2-Buffer layer issues fixed under this commit.
+This patch is same as available with PSP1.0.2 release
 
-Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com>
+The discussion is initiated on this with V4L2 mailing list.
+
+Please note that this patch is not being tested.
