    7 title: Ingenic SoCs pin controller devicetree bindings
    8 
    9 description: >
   10   Please refer to pinctrl-bindings.txt in this directory for details of the
   11   common pinctrl bindings used by client devices, including the meaning of the
   12   phrase "pin configuration node".
   13 
   14   For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
   15   may be used as GPIOs, multiplexed device functions are configured within the
   16   GPIO port configuration registers and it is typical to refer to pins using the
   17   naming scheme "PxN" where x is a character identifying the GPIO port with
   18   which the pin is associated and N is an integer from 0 to 31 identifying the
   19   pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
   20   and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B,
   21   the X1000 and the X1830 contains 4 GPIO ports, PA to PD, for a total of 128
   22   pins. The X2000 and the X2100 contains 5 GPIO ports, PA to PE, for a total of
   23   160 pins. The JZ4750, the JZ4755 the JZ4760, the JZ4770 and the JZ4780 contains
   24   6 GPIO ports, PA to PF, for a total of 192 pins. The JZ4775 contains 7 GPIO
   25   ports, PA to PG, for a total of 224 pins.
