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


The following changes since commit f114040e3ea6e07372334ade75d1ee0775c355e1:

Linux 3.18-rc1 (2014-10-19 18:08:38 -0700)

are available in the git repository at:

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.
