 ADI registers will make ADI controller registers chaos to lead incorrect results.

 Then we need one hardware spinlock to synchronize between the multiple subsystems.

28
+The new version ADI controller supplies multiple master channels for different
29
+subsystem accessing, that means no need to add hardware spinlock to synchronize,
30
+thus change the hardware spinlock support to be optional to keep backward
31
+compatibility.

 Required properties:

 - reg: Offset and length of ADI-SPI controller register space.

-- hwlocks: Reference to a phandle of a hwlock provider node.
32
-- hwlock-names: Reference to hwlock name strings defined in the same order
33
-	as the hwlocks, should be "adi".

 - #address-cells: Number of cells required to define a chip select address

 	The first value specifies the hardware channel id which is used to
