[GIT PULL] bulk GPIO changes for v3.19, take two

Linus Walleij <linus.walleij@xxxxxxxxxx> · Sun, 14 Dec 2014 22:47:34 +0100

Hi Linus,

same stuff as last time, now with a fixup patch for the previous
compile error plus I ran a few extra rounds of compile-testing.

Please pull this in for v3.19!

Yours,
Linus Walleij

  gpio: mcp23s08: fix up compilation error (2014-12-12 11:22:11 +0100)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v3.19 series:

- A new API that allows setting more than one GPIO at the
  time. This is implemented for the new descriptor-based
  API only and makes it possible to e.g. toggle a clock and
  data line at the same time, if the hardware can do this
  with a single register write. Both consumers and drivers
  need new calls, and the core will fall back to driving
  individual lines where needed. Implemented for the MPC8xxx
  driver initially.
- Patched the mdio-mux-gpio and the serial mctrl driver
  that drives modems to use the new multiple-setting API
  to set several signals simultaneously.
- Get rid of the global GPIO descriptor array, and instead
  allocate descriptors dynamically for each GPIO on a certain
  GPIO chip. This moves us closer to getting rid of the
  limitation of using the global, static GPIO numberspace.
- New driver and device tree bindings for 74xx ICs.
- New driver and device tree bindings for the VF610 Vybrid.
- Support the RCAR r8a7793 and r8a7794.
- Guidelines for GPIO device tree bindings trying to get
  things a bit more strict with the advent of combined
  device properties.
- Suspend/resume support for the MVEBU driver.
- A slew of minor fixes and improvements.
