+description: >
+  Turris Mox module status and configuration bus (over SPI)
+
+  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.

-Turris Mox module status and configuration bus (over SPI)
-
-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>;
