Seems like the majority of the other qcom pinctrl bindings docs mention that gpio-reserved-ranges is optional.

GPIOs 0 through 3 and 81 through 84 are configured to not be accessible from the application CPUs. Mark them as reserved to allow the MSM8998 MTP to boot after the introduction of 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning").
