2019-08-14dt-bindings: display: amlogic, meson-vpu: convert to yamlNeil Armstrong1-121/+0
Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Display Controller over to YAML schemas. The original example has a leftover "dmc" memory cell, that has been removed in the yaml rewrite. The port connection table has been dropped in favor of a description of each port.

The Amlogic G12A VPU is very similar to the Amlogic GXM VPU but with : - an enhanced plane blender, with up to 3 OSD planes - support for AFBC 1.2 decoder (for Bifrost GPU) - support display mode up to 4k60@75Hz Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190313141030.5958-2-narmstrong@baylibre.com
2019-03-20dt-bindings: display: amlogic, meson-vpu: exclusively use amlogic, canvasMaxime Jourdan1-3/+2
When the DRM driver for the meson platform was created, the bindings required that the DMC register region was provided. Through those DMC registers, the display driver could configure an IP called "canvas", a video lookup table used by the display IP. It was later discovered that "canvas" is actually an IP shared by other components than display: video decoder, 2D engine.. and that it wasn't possible to keep the canvas code in DRM. Over the past few months, incremental efforts have been deployed to create a standalone meson-canvas driver [1], and the DRM driver was patched to optionally use it if present [2]. This is the final step of those efforts where we simply remove any control over DMC that the meson DRM driver has. Please note that this breaks compatibility with older DTs that only provide the DMC register range but not the amlogic,canvas node.
