Message-ID: <20151014163235.GA7277@rmk-PC.arm.linux.org.uk> (raw)

David,

Please incorporate the latest Armada DRM development updates development
updates, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-armada-devel

with SHA1 7cb410cdbdc9b71e2d4f356f2e4cea0b925abb21.

These changes:

* remove support for the non-component support from the Armada DRM driver,
  switching it to component-only mode.
* create a "armada plane" to allow the primary and overlay planes to share
  some code.
* increase efficiency by using inherently atomic operations, rather than
  spinlocking to achieve atomicity.  Eg, if we want to exchange a value,
  using xchg().
* increase PM savings by stopping the external pixel clock when we're in
  DPMS mode.

Please merge this for the 4.4 merge window.  Thanks.

This will update the following files:
