[PATCH v2 2/4] dt-bindings: display: tegra: Add channel/syncpoint range properties

[Mikko Perttunen <mperttunen@nvidia.com>]

All of the resources implemented by Host1x hardware may not be available
to the software in cases where those resources are assigned to other vm
partitions through the hypervisor register region.

Add properties nvidia,channels and nvidia,syncpoints to specify the
range of resources that are accessible by this partition / virtual
machine.

The hypervisor or bootloader that configures the partitioning in the
hypervisor register region is responsible for updating the values of
these properties in accordance to the configuration.
