* [media] gpu: ipu-v3: Make use of media_bus_format enumBoris BREZILLON2014-11-14
| | | | | | | | | | | | | | | In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed enum values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in the ipu-v3 driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver uses GENERIC_IRQ_CHIP, so it needs to select GENERIC_IRQ_CHIP to avoid build error.

Removed NV21 and NV61 for now. The IDMAC doesn't understand U/V order for chroma interleaved formats, so we'd need to work around this by implenting U/V switching via the CSC unit.

* | gpu: ipu-v3: Add __ipu_idmac_reset_current_buffer()Steve Longerbeam2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds __ipu_idmac_reset_current_buffer() that resets a channel's internal current buffer pointer so that transfers start from buffer 0 on the next channel enable. This operation is required for channel linking to work correctly, for instance video capture pipelines that carry out image rotations will fail after the first streaming unless this function is called for each channel before re-enabling the channels.

Support has been added for third buffer, there is no support yet for triple-buffering in idmac channels, but this function checks buffer-ready for third buffer in case this support is added later.

* gpu: ipu-v3: Move i.MX IPUv3 core driver out of stagingPhilipp Zabel2014-06-04
The i.MX Image Processing Unit (IPU) contains a number of image processing blocks that sit right in the middle between DRM and V4L2. Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.
