A series of patches that add support for GPIO maps that have holes in
them. That is, even though a client driver has N consecutive GPIOs,
some are just unavailable for whatever reason, and the hardware should
not be accessed for those GPIOs.
Frankly, I like V5 of this patchset better, because it uses an
existing API (gpiochip_add_pin_range) and is less intrusive.
v7: fixed missing signed-off-by in patch #1

[v2] Revert "gpio: set up initial state from .get_direction()"
gpiolib: add bitmask for valid GPIO lines
[v6] pinctrl: qcom: disable GPIO groups with no pins
[v3] pinctrl: qcom: qdf2xxx: add support for new ACPI HID QCOM8002
