[PATCH 0/4] [v7] pinctrl: qcom: add support for sparse GPIOs

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

Timur Tabi (4):
  [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
