Different versions are present on various i.MX SoCs from i.MX23 to i.MX7. The latest versions on i.MX6ULL and i.MX7D have grown an additional pipeline for dithering and e-ink update processing that is ignored by this driver. This series adds a V4L2 mem-to-mem scaler/CSC driver for the PXP version found on i.MX6ULL SoCs which is a size reduced variant of the i.MX7 PXP. The driver uses only the legacy pipeline, so it should be reasonably easy to extend it to work with the older PXP versions found on i.MX6UL, i.MX6SX, i.MX6SL, i.MX28, and i.MX23. The driver supports scaling and colorspace conversion. There is currently no support for rotation, alpha-blending, and the LUTs. regards Philipp Philipp Zabel (3): dt-bindings: media: Add i.MX Pixel Pipeline binding ARM: dts: imx6ull: add pxp support media: imx-pxp: add i.MX Pixel Pipeline driver .../devicetree/bindings/media/fsl-pxp.txt | 26 + arch/arm/boot/dts/imx6ul.dtsi | 8 + arch/arm/boot/dts/imx6ull.dtsi | 6 + drivers/media/platform/Kconfig | 9 + drivers/media/platform/Makefile | 2 + drivers/media/platform/imx-pxp.c | 1455 ++++++++++++++ drivers/media/platform/imx-pxp.h | 1685 +++++++++++++++++ 7 files changed, 3191 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/fsl-pxp.txt create mode 100644 drivers/media/platform/imx-pxp.c create mode 100644 drivers/media/platform/imx-pxp.h
