| 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 JZ4740, the X1000 and the X1830 |
| 21 | + contains 4 GPIO ports, PA to PD, for a total of 128 pins. The JZ4760, the |
| 22 | + JZ4770 and the JZ4780 contains 6 GPIO ports, PA to PF, for a total of 192 |
| 23 | + pins. |
