+ - 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.

-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>;
- };
