Merge tag 'pinctrl-v4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl updates from Linus Walleij:
"Bulk pin control changes for the v4.10 kernel cycle:
No core changes this time. Mainly gradual improvement and
feature growth in the drivers.
New drivers:
- New driver for TI DA850/OMAP-L138/AM18XX pinconf
- The SX150x was moved over from the GPIO subsystem and reimagined as
a pin control driver with GPIO support in a joint effort by three
independent users of this hardware. The result was amazingly good!
- New subdriver for the Oxnas OX820
Improvements:
- The sunxi driver now supports the generic pin control bindings
rather than the sunxi-specific. Add debouncing support to the
driver.
- Simplifications in pinctrl-single adding a generic parser.
- Two downstream fixes and move the Raspberry Pi BCM2835 over to use
the generic GPIOLIB_IRQCHIP"
