Mali T628r0p1 which may be found in Samsung Exynos 5422 SOC is
definitely not dma coherent, and it is not happy with PTE_SH_OS bit set
by default in commit 728da60da7 ("iommu/io-pgtable-arm: Support
coherency for Mali LPAE"). Use PTE_SH_IS by default for non dma
coherent Mali GPUs.

Render clients should be able to create/destroy dumb object to import
and use it as render buffer in case the default DRM device is different
from the render device (i.e. kmsro).

On Exynos there is a solid color plane that is logically below all the other display planes.
This causes display artifacts due to alpha. The patch disables blending the base plane with
the solid color plane (no alpha).

In general, the gpio-line-names property should belong to the node
whereby the gpio-controller property by the related document written.
But from now, at least for the Odroid boards based on AMLogic SoC,
the property has to be in the periphs_pinctrl node so that the
function for assigning the line names recognizes that.
