+title: Ingenic SoCs pin controller devicetree bindings
+
+description: >
+  Please refer to pinctrl-bindings.txt in this directory for details of the
+  common pinctrl bindings used by client devices, including the meaning of the
+  phrase "pin configuration node".
+
+  For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
+  may be used as GPIOs, multiplexed device functions are configured within the
+  GPIO port configuration registers and it is typical to refer to pins using the
+  naming scheme "PxN" where x is a character identifying the GPIO port with
+  which the pin is associated and N is an integer from 0 to 31 identifying the
+  pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
+  and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B,
+  the X1000 and the X1830 contains 4 GPIO ports, PA to PD, for a total of 128
+  pins. The X2000 and the X2100 contains 5 GPIO ports, PA to PE, for a total of
+  160 pins. The JZ4750, the JZ4755 the JZ4760, the JZ4770 and the JZ4780 contains
+  6 GPIO ports, PA to PF, for a total of 192 pins. The JZ4775 contains 7 GPIO
+  ports, PA to PG, for a total of 224 pins.
