+ * The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU")
+ * and the ARM CPU. The ARM CPU is often thought of as the main CPU.
+ * However, the VideoCore actually controls the initial SoC boot, and hides
+ * much of the hardware behind a protocol. This protocol is transported
+ * using the SoC's mailbox hardware module.
+ *
+ * The mailbox hardware supports passing 32-bit values back and forth.
+ * Presumably by software convention of the firmware, the bottom 4 bits of the
+ * value are used to indicate a logical channel, and the upper 28 bits are the
+ * actual payload. Various channels exist using these simple raw messages. See
+ * https://github.com/raspberrypi/firmware/wiki/Mailboxes for a list. As an
+ * example, the messages on the power management channel are a bitmask of
+ * devices whose power should be enabled.
+ *
+ * The property mailbox channel passes messages that contain the (16-byte
+ * aligned) ARM physical address of a memory buffer. This buffer is passed to
+ * the VC for processing, is modified in-place by the VC, and the address then
+ * passed back to the ARM CPU as the response mailbox message to indicate
+ * request completion. The buffers have a generic and extensible format; each
+ * buffer contains a standard header, a list of "tags", and a terminating zero
+ * entry. Each tag contains an ID indicating its type, and length fields for
+ * generic parsing. With some limitations, an arbitrary set of tags may be
+ * combined together into a single message buffer. This file defines structs
+ * representing the header and many individual tag layouts and IDs.

+Exynos Thermal management Unit
+
+Required properties:
+
+ - compatible : Should be "samsung,exynos-tmu" for TMU
+ - samsung,min-temp : Minimum temperature value (25 degree celsius)
+	- Current temperature of SoC should be more than this value.
+ - samsung,max-temp : Maximum temperature value (125 degree celsius)
+	- Current temperature of SoC should be less than this value.
+ - samsung,start-warning : Temperature at which TMU starts giving warning (degree celsius)
+ - samsung,start-tripping : Temperature at which TMU shuts down the system (degree celsius)
+ - samsung,hw-tripping : Temperature at which hardware tripping should happen
+	in case TMU fails to power off (degree celsius)
+ - samsung,efuse-min-value : SOC efuse min value (Constant 40)
+	- efuse-value should be more than this value.
+ - samsung,efuse-value : SOC actual efuse value (Literal value)
+	- This is the data trimming info.
+	- This value is used to calculate measuring error.
+ - samsung,efuse-max-value : SoC max efuse value (Constant 100)
+	- efuse-value should be less than this value.
+ - samsung,slope : Default value 274761730 (Constant 0x1060_8802).
+	- This is the default value for TMU_CONTROL register.
+	- It sets the gain of amplifier to the positive-tc generator block.
+	- It selects thermal tripping mode and enables thermal tripping.
+ - samsung,dc-value : Measured data calibration value (Constant 25)
+	- Used for tempearture calculation.
+	- This is 25 because temperature measured is always above 25 degrees.
+
+
+Example:
