Subject: [PATCH v3 0/4] i.MX PXP scaler/CSC driver
Date: Thu, 6 Sep 2018 11:02:11 +0200 [thread overview]
Message-ID: <20180906090215.15719-1-p.zabel@pengutronix.de> (raw)
The Pixel Pipeline (PXP) is a memory-to-memory graphics processing
engine that supports scaling, colorspace conversion, alpha blending,
rotation, and pixel conversion via lookup table. 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.
Changes since v2:
- fix Kconfig whitespace
- remove unused defines
- fix video_unregister_device/v4l2_m2m_release order in pxp_remove
- use GPL-2.0+ instead of GPL-2.0-or-later SPDX license identifer
- remove pxp_default_ycbcr_enc/quantization, always map to default
encoding/quantization
- rename pxp_fixup_colorimetry to pxp_fixup_colorimetry_cap
regards
Philipp
