Subject: [PATCH 0/4] soc: amlogic: add meson-canvas driver
Date: Wed,  1 Aug 2018 20:51:24 +0200
Message-ID: <20180801185128.23440-1-maxi.jourdan@wanadoo.fr> (raw)

Amlogic SoCs feature a set of 256 canvas that act as pixel buffer
descriptors. Some IPs like the display and video decoders access those
pixels by using canvas IDs rather than direct phy addresses.

As such, allocating/manipulating canvases can be done concurrently and
there is a need for a standalone, lock-aware canvas provider module.

Currently, canvas code lies in the drm/meson module as it is the sole
user.

This patchset adds such canvas provider module and converts drm/meson to
using it, stripping/moving the current canvas code.

Maxime Jourdan (4):
  soc: amlogic: add meson-canvas driver
  dt-bindings: soc: amlogic: add meson-canvas documentation
  ARM64: dts: meson-gx: add dmcbus and canvas nodes.
  drm/meson: convert to the new canvas module
