Subject: [GIT PULL] GPIO changes for the v4.4 kernel cycle
Hi Linus,
here is the bulk of GPIO changes for the v4.4 development cycle.
The details are in the signed tag as usual.
The only changes hitting outside drivers/gpio are in the pin control
subsystem and these seem to have settled nicely in linux-next.
Development mistakes and catfights are nicely documented in the
reverts as you can see. The outcome of the ABI fight is that we're
working on a chardev ABI for GPIO now, where hope to show results
for the v4.5 kernel.
Please pull it in!
Yours,
Linus Walleij

gpio: fix up SPI submenu (2015-11-01 10:50:19 +0100)
----------------------------------------------------------------
This is the bulk of GPIO changes for v4.4:
GPIO core:
- Define and handle flags for open drain/open collector
and open source/open emitter, also know as "single-ended"
configurations.
- Generic request/free operations that handle calling out
to the (optional) pin control backend.
- Some refactoring related to an ABI change that did not
happen, yet provide useful.
- Added a real-time compliance checklist. Many GPIO chips
have irqchips, and need to think this over with the RT
patches going upstream.
- Restructure, fix and clean up Kconfig menus a bit.
New drivers:
- New driver for AMD Promony.
- New driver for ACCES 104-IDIO-16, a port-mapped I/O
card, ISA-style. Very retro.
Subdriver changes:
- OMAP changes to handle real time requirements.
- Handle trigger types for edge and level IRQs on PL061
properly. As this hardware is very common it needs to
set a proper example for others to follow.
- Some container_of() cleanups.
- Delete the unused MSM driver in favor of the driver that
is embedded inside the pin control driver.
- Cleanup of the ath79 GPIO driver used by many, many
OpenWRT router targets.
- A consolidated IT87xx driver replacing the earlier
very specific IT8761e driver.
- Handle the TI TCA9539 in the PCA953x driver. Also
handle ACPI devices in this subdriver.
- Drop xilinx arch dependencies as these FPGAs seem to
profilate over a few different architectures. MIPS and
ARM come to mind.
