Subject: [v5,3/4] ARM: dts: qcom: add gpio-ranges property

From: Christian Lamparter <[email-masked]>
Date: Mon, 21 May 2018 22:57:38 +0200

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.
