* [media] davinci/vpss: add helper functions for setting hw paramsManjunath Hadli2012-12-212-0/+48
| | | | | | | | | | | | Add vpss helper functions to be used in the main driver for setting hardware parameters.

| | | | | | | | | We already have the same delay in i2c_w8, but it was missing from i2c_w1, adding this delay fixes the Microsoft VX-3000 camera often (but not always) streaming video data with a very green-ish tint.

* [media] fimc-lite: Add ISP FIFO output supportSylwester Nawrocki2012-12-213-35/+120
| | | | | | | | | | | | | | | | Add second source media pad for the FIFO data output to FIMC-IS and implement subdev s_stream op for configurations where FIMC-LITE is used as a glue logic between FIMC-IS and MIPI-CSIS or an image sensor. The second source media pad will be linked to the FIMC-LITE video node. For proper configuration the attached image sensor/video encoder properties are needed, like video bus type, signal polarities, etc. For this purpose there is a small routine added that walks the pipeline and returns the sensor subdev.

* [media] s5p-fimc: Fix horizontal/vertical image flipSylwester Nawrocki2012-12-211-4/+4
| | | | | | | | | | | | | | | Setting FIMC_REG_CITRGFMT_FLIP_X_MIRROR bit causes X-axis image flip (vertical flip) and thus it corresponds to V4L2_CID_VFLIP. Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP. Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip.
