  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.
