+Required properties:
+ - compatible : Should be "cznic,moxtet"
+ - #address-cells : Has to be 1
+ - #size-cells : Has to be 0
+ - spi-cpol : Required inverted clock polarity
+ - spi-cpha : Required shifted clock phase
+ - interrupts : Must contain reference to the shared interrupt line
+ - interrupt-controller : Required
+ - #interrupt-cells : Has to be 1
+
+For other required and optional properties of SPI slave nodes please refer to
+../spi/spi-bus.txt.
+
+Required properties of subnodes:
+ - reg : Should be position on the Moxtet bus (how many Moxtet
+ modules are between this module and CPU module, so
+ either 0 or a positive integer)
+
+The driver finds the devices connected to the bus by itself, but it may be
+needed to reference some of them from other parts of the device tree. In that
+case the devices can be defined as subnodes of the moxtet node.
+
+Example:
+
+ moxtet@1 {
+ compatible = "cznic,moxtet";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <1>;
+ spi-max-frequency = <10000000>;
+ spi-cpol;
+ spi-cpha;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ interrupt-parent = <&gpiosb>;
+ interrupts = <5 IRQ_TYPE_EDGE_FALLING>;

-Device tree bindings for Allwinner DE2/3 bus
-
-The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
-to be claimed for enabling the access. The DE3 on Allwinner H6 is at the same
-situation, and the binding also applies.
-
-Required properties:
-
- - compatible: Should be one of:
- - "allwinner,sun50i-a64-de2"
- - "allwinner,sun50i-h6-de3", "allwinner,sun50i-a64-de2"
- - reg: A resource specifier for the register space
- - #address-cells: Must be set to 1
- - #size-cells: Must be set to 1
- - ranges: Must be set up to map the address space inside the
- DE2, for the sub-blocks of DE2.
- - allwinner,sram: the SRAM that needs to be claimed
-
-Example:
-
- de2@1000000 {
- compatible = "allwinner,sun50i-a64-de2";
- reg = <0x1000000 0x400000>;
- allwinner,sram = <&de2_sram 1>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x1000000 0x400000>;

- clock-names = "mod",
- "bus";

- #clock-cells = <1>;
