[PATCH 0/4] [v8] pinctrl: qcom: add support for sparse GPIOs

[timur@codeaurora.org (Timur Tabi)]

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.

Note that this version does not address the failure of gpiod_get()
when GPIO 0 is not available.  I don't know how to fix that because I 
don't understand what gpiod_get() is trying to do.

Also note that I would prefer to have the call to gpiochip_available()
be inside gpiod_request(), but I don't know how to get the GPIO index
inside that function (without adding a function a parameter).

In other words, there will be a v9, but I need help.


v8:
  rebased onto 4.15-rc1
  fix issues raised during review of v7

Timur Tabi (4):
  [v2] Revert "gpio: set up initial state from .get_direction()"
  [v2] gpiolib: add bitmask for valid GPIO lines
  [v7] pinctrl: qcom: disable GPIO groups with no pins
  [v4] pinctrl: qcom: qdf2xxx: add support for new ACPI HID QCOM8002
