Changes for v4:
-Updated bindings for lx2160a clockgen and dcfg
-Modified commit message for lx2160a clockgen changes
-Updated interrupt property with macro definition
-Added required enable-method property to each core node with psci value
-Removed unused node syscon in device tree
-Removed blank lines in device tree fsl-lx2160a.dtsi
-Updated uart node compatible sbsa-uart first
-Added and defined vcc-supply property to temperature sensor node in
device tree fsl-lx2160a-rdb.dts
Changes for v3:
-Split clockgen support patch into below two patches:
- a)Updated array size of cmux_to_group[] with NUM_CMUX+1 to include -1
terminator and p4080 cmux_to_group[] array with -1 terminator
- b)Add clockgen support for lx2160a
Changes for v2:
- Modified cmux_to_group array to include -1 terminator
- Revert NUM_CMUX to original value 8 from 16
- Remove “As LX2160A is 16 core, so modified value for NUM_CMUX”
in patch "[PATCH 3/5] drivers: clk-qoriq: Add clockgen support for
lx2160a" description
- Populated cache properties for L1 and L2 cache in lx2160a device-tree.
- Removed reboot node from lx2160a device-tree as PSCI is implemented.
- Removed incorrect comment for timer node interrupt property in
lx2160a device-tree.
- Modified pmu node compatible property from "arm,armv8-pmuv3" to
"arm,cortex-a72-pmu" in lx2160a device-tree
- Non-standard aliases removed in lx2160a rdb board device-tree
- Updated i2c child nodes to generic name in lx2160a rdb device-tree.
Changes for v1:
- Add compatible string for LX2160A clockgen support
- Add compatible string to initialize LX2160A guts driver
- Add compatible string for LX2160A support in dt-bindings
- Add dts file to enable support for LX2160A SoC and LX2160A RDB
(Reference design board)

Quote from devicetree specification:
The device_type property was used in IEEE 1275 to describe the device’s
FCode programming model. Because DTSpec does not have FCode, new use of
the property is deprecated, and it should be included only on cpu and
memory nodes for compatibility with IEEE 1275–derived devicetrees.

The node name should probably be named like regulator-sb3v3 or
something, so that the pattern can be followed when we have another
fixed regulator to be added.

The name should be something we can find on board schematics.

Have a newline between properties and child node.

Ok, Agree this is fixed 3.3 standby voltage for i2c subchannels
Updating to regulator-sb3v3

Sure, I will update SMPS name which provide fixed 3.3 stand-by voltage

There is only one clock-unit, Bootloader(U-boot) require sysclk node during device tree fix-up as different platform support varied platform frequency as per reset configuration word used.
Referred other ARM based platform with one clock using name as x: x
