Merge tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"Main pin control pull request for the v3.13 cycle.
The changes hitting arch/blackfin are ACKed by the Blackfin
maintainer, and the device tree bindings are ACKed to the extent
possible by someone from the device tree maintainers group.
- Blackfin ADI pin control driver, we move yet another architecture
under this subsystem umbrella.
- Incremental updates to the Renesas Super-H PFC pin control driver.
New subdriver for the r8a7791 SoC.
- Non-linear GPIO ranges from the gpiolib side of things, this
enabled simplified device tree bindings by referring entire groups
of pins on some pin controller to act as back-end for a certain
GPIO-chip driver.
- Add the Abilis TB10x pin control driver used on the ARC
architecture. Also the corresponding GPIO driver is merged through
this tree, so the ARC has full support for pins and GPIOs after
this.
- Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller
instances. The i.MX1 and i.MX27 is an entirely new family
(silicon) of controllers whereas i.MX50 is a variant of the
previous supported controller.
- Then the usual slew of fixes, cleanups and incremental updates"
The ARC DT changes are apparently still pending, that hopefully gets
sorted out in a timely manner.
