Subject: [PATCH v2 1/4] dt-bindings: devfreq: event: convert Samsung Exynos NoCP to dtschema

Convert Samsung Exynos NoC Probe bindings to DT schema format using
json-schema.

New bindings contain copied description from previous bindings document,
therefore the license is set as GPL-2.0-only.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com>

-* Samsung Exynos NoC (Network on Chip) Probe device
-
-The Samsung Exynos542x SoC has NoC (Network on Chip) Probe for NoC bus.
-NoC provides the primitive values to get the performance data. The packets
-that the Network on Chip (NoC) probes detects are transported over
-the network infrastructure to observer units. You can configure probes to
-capture packets with header or data on the data request response network,
-or as traffic debug or statistic collectors. Exynos542x bus has multiple
-NoC probes to provide bandwidth information about behavior of the SoC
-that you can use while analyzing system performance.
-
-Required properties:
-- compatible: Should be "samsung,exynos5420-nocp"
-- reg: physical base address of each NoC Probe and length of memory mapped region.
-
-Optional properties:
-- clock-names : the name of clock used by the NoC Probe, "nocp"
-- clocks : phandles for clock specified in "clock-names" property
-
-Example : NoC Probe nodes in Device Tree are listed below.
-
-	nocp_mem0_0: nocp@...a1000 {
-		compatible = "samsung,exynos5420-nocp";
-		reg = <0x10CA1000 0x200>;
