-Lantiq SoC Serial To Parallel (STP) GPIO controller
-
-The Serial To Parallel (STP) is found on MIPS based Lantiq socs. It is a
-peripheral controller used to drive external shift register cascades. At most
-3 groups of 8 bits can be driven. The hardware is able to allow the DSL modem
-to drive the 2 LSBs of the cascade automatically.
-
-
-Required properties:
-- compatible : Should be "lantiq,gpio-stp-xway"
-- reg : Address and length of the register set for the device
-- #gpio-cells : Should be two.  The first cell is the pin number and
-  the second cell is used to specify optional parameters (currently
-  unused).
-- gpio-controller : Marks the device node as a gpio controller.
-
-Optional properties:
-- lantiq,shadow : The default value that we shall assume as already set on the
-  shift register cascade.
-- lantiq,groups : Set the 3 bit mask to select which of the 3 groups are enabled
-  in the shift register cascade.
-- lantiq,dsl : The dsl core can control the 2 LSBs of the gpio cascade. This 2 bit
-  property can enable this feature.
-- lantiq,phy1 : The gphy1 core can control 3 bits of the gpio cascade.
-- lantiq,phy2 : The gphy2 core can control 3 bits of the gpio cascade.
-- lantiq,rising : use rising instead of falling edge for the shift register

-Example:
-
-gpio1: stp@E100BB0 {
-	compatible = "lantiq,gpio-stp-xway";
-	reg = <0xE100BB0 0x40>;
-	#gpio-cells = <2>;
-	gpio-controller;
-
-	lantiq,shadow = <0xffff>;
-	lantiq,groups = <0x7>;
-	lantiq,dsl = <0x3>;
-	lantiq,phy1 = <0x7>;
-	lantiq,phy2 = <0x7>;
-	/* lantiq,rising; */
-};
