This is the bulk of pin control changes for the v4.16 kernel cycle:

Core changes:

- After lengthy discussions and partly due to my ignorance, we have
  merged a patch making pinctrl_force_default() and pinctrl_force_sleep()
  reprogram the states into the hardware of any hogged pins, even
  if they are already in the desired state. This only apply to hogged
  pins since groups of pins owned by drivers need to be managed by
  each driver, lest they could not do things like runtime PM and
  put pins to sleeping state even if the system as a whole is not
  in sleep.

New drivers:

- New driver for the Microsemi Ocelot SoC. This is used in ethernet
  switches.

- The X-Powers AXP209 GPIO driver was extended to also deal with pin
  control and moved over from the GPIO subsystem. This circuit is
  a mixed-mode integrated circuit which is part of AllWinner designs.

- New subdriver for the Qualcomm MSM8998 SoC, core of a high end
  mobile devices (phones) chipset.

- New subdriver for the ST Microelectronics STM32MP157 MPU and
  STM32F769 MCU from the STM32 family.

- New subdriver for the MediaTek MT7622 SoC. This is used for routers,
  repeater, gateways and such network infrastructure.

- New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has
  multimedia features and target "smart devices", I guess in-car
  entertainment, in-flight entertainment, industrial control panels etc.

General improvements:

- Incremental improvements on the SH-PFC subdrivers for things like
  the CAN bus.

- Enable the glitch filter on Baytrail GPIOs used for interrupts.

- Proper handling of pins to GPIO ranges on the Semtec SX150X

- An IRQ setup ordering fix on MCP23S08.

- A good set of janitorial coding style fixes.
