+Properties for Jedec JC-42.4 compatible temperature sensors

+Required properties:
+- compatible: May include a device-specific string consisting of the
+	      manufacturer and the name of the chip. A list of supported

+	      Must include "jedec,jc-42.4-temp" for any Jedec JC-42.4
+	      compatible temperature sensor.
+
+	      Supported chip names:
+		adi,adt7408
+		atmel,at30ts00
+		atmel,at30tse004
+		onnn,cat6095
+		onnn,cat34ts02

[PATCH 2/3] hwmon: (jc42) Add support for generic JC-42.4 devicetree binding

[Guenter Roeck]

With this change, JC-42.4 compatible temperature sensors can be configured
in devicetree by providing a generic "jedec,jc-42.4-temp" binding.

[PATCH 3/3] ARM: dts: lpc4350-hitex-eval: Fix binding for SE97

[Guenter Roeck]

The 'compatible = "nxp,jc42"' binding only happened to work because
the Linux driver is named jc42. The driver now supports generic
bindings for JC-42 compatible chips, so use the generic binding instead.
