[PATCH 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.

This patch set depends on the acceptance of:
  [PATCH 1/2] dt-bindings: document renesas-ostm timer
  [PATCH 2/2] clocksource: Add renesas-ostm timer driver

  ARM: dts: r7s72100: add ostm clock to device tree

I think this change should be folded into "[PATCH 2/3] ARM: dts: r7s72100: add
ostm to device tree" ;-)
