Subject: [PATCH 00/20] drm: rcar-du: Add Color Management Module (CMM)
Date: Thu, 6 Jun 2019 16:22:00 +0200 [thread overview]
Message-ID: <20190606142220.1392-1-jacopo+renesas@jmondi.org> (raw)
Hello,
this series add support for the Color Management Module (CMM) found on
the R-Car Display Unit output channels. CMM is present in most of the Gen3
SoCs (V3-H and V3-M excluded) and in Gen2 (which is not supported by the
series).
The CMM allows setting 1-D and 3-D gamma tables and generates histograms on
images before they are directed to the DU's output pads.
The current implementation only supports configuration of the 1-D gamma table,
by using the GAMMA_LUT KMS property. On top of this current version, more
advanced features such as 3-D LUT support and histogram generation can be
later implemented.
The series starts by adding the bindings definitions and by registering the
clock providers for the various SoCs that support the CMM. It then registers
CMMs in the SoC device tree sources and finally adds a driver for the CMM
itself and integrates it in the rcar-du driver infrastructure to register,
enable and update the CMM units.
Tested on M3-W Salvator-x on HDMI connector and on E3 Ebisu on VGA connector
by injecting a 'color inversion' gamma table using a patched version of
the KMS++ kmstest utility[1], and observing the CMM applies the correction
matrix properly.
Series based on Laurent's drm/du/next branch at
git://linuxtv.org/pinchartl/media.git
Thanks
