title: Ingenic SoCs pin controller
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.
