gpu: ipu-v3: prg: add function to get channel configure status

2019-02-22T10:58:45Z

This allows channels using the PRG to check if a requested configuration update has been applied or is still pending. Signed-off-by: Lucas Stach [p.zabel@pengutronix.de: inverted logic: done -> pending] Signed-off-by: Philipp Zabel

media: gpu: ipu-v3: Add planar support to interlaced scan

2019-01-16T19:12:20Z

To support interlaced scan with planar formats, cpmem SLUV must be programmed with the correct chroma line stride. For full and partial planar 4:2:2 (YUV422P, NV16), chroma line stride must be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12), chroma line stride must _not_ be doubled, since a single chroma line is shared by two luma lines.

media: gpu: ipu-csi: Swap fields according to input/output field types

2019-01-16T19:11:42Z

The function ipu_csi_init_interface() was inverting the F-bit for NTSC case, in the CCIR_CODE_1/2 registers. The result being that for NTSC bottom-top field order, the CSI would swap fields and capture in top-bottom order. Instead, base field swap on the field order of the input to the CSI, and the field order of the requested output. If the input/output fields are sequential but different, swap fields, otherwise do not swap. This requires passing both the input and output mbus frame formats to ipu_csi_init_interface(). Move this code to a new private function ipu_csi_set_bt_interlaced_codes() that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and possibly interlaced BT.1120 in the future). When detecting input video standard from the input frame width/height, make sure to double height if input field type is alternate, since in that case input height only includes lines for one field.

gpu: ipu-v3: ipu-ic: allow to manually set resize coefficients

2018-11-05T13:40:06Z

For tiled scaling, we want to compute the scaling coefficients externally in such a way that the interpolation overshoots tile boundaries and samples up to the first pixel of the next tile. Prepare to override the resizing coefficients from the image conversion code. Signed-off-by: Philipp Zabel Acked-by: Steve Longerbeam Tested-by: Steve Longerbeam

gpu: ipu-v3: Add chroma plane offset overrides to ipu_cpmem_set_image()

2018-11-05T13:40:06Z

Allow the caller of ipu_cpmem_set_image() to override the latters calculation of the chroma plane offsets, by adding override U/V plane offsets to 'struct ipu_image'. Signed-off-by: Steve Longerbeam Tested-by: Philipp Zabel Signed-off-by: Philipp Zabel

gpu: ipu-v3: Add support for double read/write reduction

2017-06-08T06:57:18Z

Allow to skip writing odd chroma rows by setting the RDRW bit for 4:2:0 chroma subsampled formats for any IDMAC write channel. This also allows to skip reading odd rows for the VDIC read channel. Signed-off-by: Philipp Zabel

gpu: ipu-v3: add support for separate alpha channels

2017-03-15T14:42:31Z

The IPUv3 can read 8-bit alpha values from a separate IDMAC channel driven by the Alpha Transparency Controller (ATC) for the graphics IDMAC channels. This allows to reduce memory bandwidth via a conditional read mechanism or to support planar YUV formats with alpha transparency. Signed-off-by: Philipp Zabel
