Merge tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for the v4.4 development cycle.
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.
Summary of changes:
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"
