[PATCH 03/14] davinci: vpfe: add IPIPE support for media controller driver

[Prabhakar Lad]

From: Manjunath Hadli <manjunath.hadli@xxxxxx>

Add the IPIPE interfacing layer to the vpfe driver. This patch adds dm365
specific implementation of the genric imp_hw_interface interface for
programming the IPIPE block, mainly setting the resizer and previewer
configuration parameters. This is built as an independent module.

+ *
+ *
+ * Previewer allows fine tuning of the input image using different
+ * tuning modules in IPIPE. Some examples :- Noise filter, Defect
+ * pixel correction etc. It essentially operate on Bayer Raw data
+ * or YUV raw data. To do image tuning, application call,
+ * PREV_QUERY_CAP, and then call PREV_SET_PARAM to set parameter
+ * for a module.
+ *
+ *
+ * Resizer allows upscaling or downscaling a image to a desired
+ * resolution. There are 2 resizer modules. both operating on the
+ * same input image, but can have different output resolution.
