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

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