+description:
+  This SGPIO controller is for ASPEED AST2400, AST2500 and AST2600 SoC,
+  AST2600 have two sgpio master one with 128 pins another one with 80 pins,
+  AST2500/AST2400 have one sgpio master with 80 pins. Each of the Serial
+  GPIO pins can be programmed to support the following options
+  - Support interrupt option for each input port and various interrupt
+    sensitivity option (level-high, level-low, edge-high, edge-low)
+  - Support reset tolerance option for each output port
+  - Directly connected to APB bus and its shift clock is from APB bus clock
+    divided by a programmable value.
+  - Co-work with external signal-chained TTL components (74LV165/74LV595)

-Aspeed SGPIO controller Device Tree Bindings
---------------------------------------------
-
-This SGPIO controller is for ASPEED AST2500 SoC, it supports up to 80 full
-featured Serial GPIOs. Each of the Serial GPIO pins can be programmed to
-support the following options:
-- Support interrupt option for each input port and various interrupt
-  sensitivity option (level-high, level-low, edge-high, edge-low)
-- Support reset tolerance option for each output port
-- Directly connected to APB bus and its shift clock is from APB bus clock
-  divided by a programmable value.
-- Co-work with external signal-chained TTL components (74LV165/74LV595)
-
-Required properties:
-
-- compatible : Should be one of
-  "aspeed,ast2400-sgpio", "aspeed,ast2500-sgpio"
-- #gpio-cells : Should be 2, see gpio.txt
-- reg : Address and length of the register set for the device
-- gpio-controller : Marks the device node as a GPIO controller
-- interrupts : Interrupt specifier, see interrupt-controller/interrupts.txt
-- interrupt-controller : Mark the GPIO controller as an interrupt-controller
-- ngpios : number of *hardware* GPIO lines, see gpio.txt. This will expose
-  2 software GPIOs per hardware GPIO: one for hardware input, one for hardware
-  output. Up to 80 pins, must be a multiple of 8.
-- clocks : A phandle to the APB clock for SGPM clock division
-- bus-frequency : SGPM CLK frequency
-
-The sgpio and interrupt properties are further described in their respective
-bindings documentation:
-
-- Documentation/devicetree/bindings/gpio/gpio.txt
-- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-  Example:
-	sgpio: sgpio@1e780200 {
-		#gpio-cells = <2>;
-		compatible = "aspeed,ast2500-sgpio";
-		gpio-controller;
-		interrupts = <40>;
-		reg = <0x1e780200 0x0100>;
-		clocks = <&syscon ASPEED_CLK_APB>;
-		interrupt-controller;
-		ngpios = <8>;
-		bus-frequency = <12000000>;
-	};
