2aa0d4c881 dt-bindings: bus: qcom,ssc-block-bus: rework arrays and drop redundant minItems
There is no need to specify "minItems" if it equals to "maxItems".  On the
other hand number of items in an array can be specified via describing
items, which might bring some additional information.  This simplifies a
bit the binding.

0b9fe9b779 dt-bindings: bus: add device tree bindings for qcom,ssc-block-bus
Adds bindings for the AHB bus which exposes the SSC block in the global
address space. This bus (and the SSC block itself) is present on certain
qcom SoCs.

In typical configuration, this bus (as some of the clocks and registers
that we need to manipulate) is not accessible to the OS, and the
resources on this bus are indirectly accessed by communicating with a
hexagon CPU core residing in the SSC block. In this configuration, the
hypervisor is the one performing the bus initialization for the purposes
of bringing the haxagon CPU core out of reset.

However, it is possible to change the configuration, in which case this
binding serves to allow the OS to initialize the bus.
