[PATCH v4] arm64: dts: renesas: r8a7795: Move nodes which have no reg property out of bus

From: Simon Horman <hidden>
Date: 2017-11-30 10:25:39

Move pmu_a5[73], timer and thermal-zones nodes from soc node to root node.
The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

This problem is flagged by the compiler as follows:

v4
* Use interrupts-extended rather than interrupt-parent + interrupts
  in /pmu_* and /timer nodes as seems to be preferred.
v3
* Add interrupt-parent property to /pmu_* and /timer nodes as
  it is no longer inherited from the parent node
v2
* Preserve alphabetical order of nodes present in root node.

I have applied this with Geert's review tag from v2.
