Hi Linus,

here is the bulk of GPIO changes for the v3.19 kernel series.
The major external change is the new API to driver several GPIOs
simultaneously, and the major internal change is that we're getting
rid of a static array of GPIO descriptors and again moving away,
slowly, from the global GPIO numberspace.

There is a patch hitting the TTY/serial subsystem, it has been
ACKed by Greg.

More details in the signed tag as usual.

Please pull it in!

Yours,
Linus Walleij

gpio: pl061: document gpio-ranges property for bindings file
(2014-12-03 14:46:27 +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.
