Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.1 development cycle:
- A new GPIO hogging mechanism has been added. This can be used on
boards that want to drive some GPIO line high, low, or set it as
input on boot and then never touch it again. For some embedded
systems this is bliss and simplifies things to a great extent.
- Some API cleanup and closure: gpiod_get_array() and
gpiod_put_array() has been added to get and put GPIOs in bulk as
was possible with the non-descriptor API.
- Encapsulate cross-calls to the pin control subsystem in
<linux/gpio/driver.h>. Now this should be the only header any GPIO
driver needs to include or something is wrong. Cleanups
restricting drivers to this include are welcomed if tested.
- Sort the GPIO Kconfig and split it into submenus, as it was
becoming and unstructured, illogical and unnavigatable mess. I
hope this is easier to follow. Menus that require a certain
subsystem like I2C can now be hidden nicely for example, still
working on others.
- New drivers:
- New driver for the Altera Soft GPIO.
- The F7188x driver now handles the F71869 and F71869A variants.
- The MIPS Loongson driver has been moved to drivers/gpio for
consolidation and cleanup.
- Cleanups:
- The MAX732x is converted to use the GPIOLIB_IRQCHIP
infrastructure.
- The PCF857x is converted to use the GPIOLIB_IRQCHIP
infrastructure.
- Radical cleanup of the OMAP driver.
- Misc:
- Enable the DWAPB GPIO for all architectures. This is a "hard
IP" block from Synopsys which has started to turn up in so
diverse architectures as X86 Quark, ARC and a slew of ARM
systems. So even though it's not an expander, it's generic
enough to be available for all.
- We add a mock GPIO on Crystalcove PMIC after a long discussion
with Daniel Vetter et al, tracing back to the shootout at the
kernel summit where DRM drivers and sub-componentization was
discussed. In this case a mock GPIO is assumed to be the best
compromise gaining some reuse of infrastructure without making
DRM drivers overly complex at the same time. Let's see"
