-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.

-
-For IPQ806x targets, TZ protects the registers that are used to
-configure the routing of interrupts to a target processor.
-To resolve this, this patch uses scm call to route GPIO interrupts
-to application processor. Also the scm call interface is changed.

-
-In Certain QCOM SoCs like ipq8064, apq8064, msm8960, msm8974
-that has KRAIT processors the voltage/current value of each OPP
-varies based on the silicon variant in use.
-
-The required OPP related data is determined based on
-the efuse value. This is similar to the existing code for
-kryo cores. So adding support for krait cores here.

-
-Some SoC based on ipq8064/5 needs to be limited to pci GEN1 speed due to
-some hardware limitations. Add support for speed setting defined by the
-max-link-speed binding. If not defined the max speed is set to GEN2 by
-default.

-Subject: phy: qualcomm: fix setting of tx_deamp_3_5db when device property
- read fails
-
-Currently when reading of the device property for "qcom,tx-deamp_3_5db"
-fails the default is being assigned incorrectly to phy_dwc3->rx_eq. This
-looks like a copy-n-paste error and in fact should be assigning the
-default instead to phy_dwc3->tx_deamp_3_5db
-
-Addresses-Coverity: ("Copy-paste error")
-Fixes: ef19b117b834 ("phy: qualcomm: add qcom ipq806x dwc usb phy driver")
