New drivers:
- New driver for Oxnas pin control and GPIO. This ARM-based chipset
is used in a few storage (NAS) type devices.
- New driver for the MAX77620/MAX20024 pin controller portions.
- New driver for the Intel Merrifield pin controller.
New subdrivers:
- New subdriver for the Qualcomm MDM9615
- New subdriver for the STM32F746 MCU
- New subdriver for the Broadcom NSP SoC.
Cleanups:
- Demodularization of bool compiled-in drivers.
Apart from this there is just regular incremental improvements to
a lot of drivers, especially Uniphier and PFC.

Merge tag 'pinctrl-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.8 kernel cycle.
Nothing stands out as especially exiting: new drivers, new subdrivers,
lots of cleanups and incremental features.
Business as usual.
New drivers:
- New driver for Oxnas pin control and GPIO. This ARM-based chipset
is used in a few storage (NAS) type devices.
- New driver for the MAX77620/MAX20024 pin controller portions.
- New driver for the Intel Merrifield pin controller.
New subdrivers:
- New subdriver for the Qualcomm MDM9615
- New subdriver for the STM32F746 MCU
- New subdriver for the Broadcom NSP SoC.
