[PATCH v3 0/3] ARM: dts: add ostm support for r7s72100

[Chris Brandt]

This patch set enables the use of the newly created driver
renesas-ostm.c for the r7s72100 SoC.

v3:
* Changed ostm@fcfec000 to timer@fcfec000
* Added power-domains to nodes

v2:
* The biggest change was now the channels are independent of each
  other and have separate nodes in the DT. The first probed will
  be set up as a clock source, and any additional channels probed
  will become a clock event.

Thanks Chris,

I have queued this series up for v4.11.
It should appear in net-next in linux-next day or so.
