gpu: ipu-v3: Fix IC control register offset

2015-01-27T15:28:01Z

The IC register offset is at +0x20000 relative to the control module registers on all IPUv3 versions. This patch fixes wrong values for i.MX51 and i.MX53. Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add ipu_dump()

2014-09-02T12:55:56Z

Adds ipu_dump() which dumps IPU register state to debug. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add more planar formats support

2014-09-02T12:55:55Z

Adds support for the following planar and partial-planar formats: YUV422 NV12 NV16 Signed-off-by: Dmitry Eremin-Solenikov Signed-off-by: Mohsin Kazmi Signed-off-by: Steve Longerbeam Unified base offset and Y plane offset into a single variable, moved all ipu_cpmem_set_buffer calls to a single location. 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_lock_enable()

2014-09-02T12:55:51Z

Adds ipu_idmac_lock_enable(), which enables or disables channel burst locking. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add ipu_idmac_enable_watermark()

2014-09-02T12:55:50Z

Adds the function ipu_idmac_enable_watermark(), which enables or disables watermarking in the IDMAC channel. Enabling watermarking can increase a channel's AXI bus arbitration priority. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add ipu_stride_to_bytes()

2014-09-02T12:55:50Z

Adds ipu_stride_to_bytes(), which converts a pixel stride to bytes, suitable for passing to cpmem. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add __ipu_idmac_reset_current_buffer()

2014-09-02T12:55:49Z

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.

gpu: ipu-v3: Add ipu_idmac_clear_buffer()

2014-09-02T12:55:49Z

Add the reverse of ipu_idmac_select_buffer(), that is, clear a buffer ready status in a channel. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add ipu_idmac_buffer_is_ready()

2014-09-02T12:55:48Z

Add ipu_idmac_buffer_is_ready(), returns true if the given buffer in the given channel is set ready (owned by IPU), or false if not ready (owned by CPU core). 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.
