+
+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.
