| 21 | This patch adds the gpio-ranges property to almost all of |
| 22 | the Qualcomm ARM platforms that utilize the pinctrl-msm |
| 23 | framework. |
| 24 | |
| 25 | The gpio-ranges property is part of the gpiolib subsystem. |
| 26 | As a result, the binding text is available in section |
| 27 | "2.1 gpio- and pin-controller interaction" of |
| 28 | Documentation/devicetree/bindings/gpio/gpio.txt |
| 29 | |
| 30 | For more information please see the patch titled: |
| 31 | "pinctrl: msm: fix gpio-hog related boot issues" from |
| 32 | this series. |

| 40 | To help with git bisect, the DT update patch has been intentionally |
| 41 | placed after the "pinctrl: msm: fix gpio-hog related boot issues". |
| 42 | Otherwise - if the order was reveresed - and bisect decides to split |
| 43 | between these two patches, the gpiochip_add_pin_ranges() function |
| 44 | will be executed twice with the same parameters for the same pinctrl. |
