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.
