Linus Torvalds 5ab356626f Pin control bulk changes for the v4.11 kernel cycle: 
Core changes:
 
 - Switch the generic pin config argument from 16 to 24 bits,
   only use 8 bits for the configuration type. We might need to
   encode more information about a certain setting than we need
   to encode different generic settings.
 
 - Add a cross-talk API to the pin control GPIO back-end,
   utilizing pinctrl_gpio_set_config() from GPIO drivers that
   want to set up a certain pin configuration in the back-end.
   This also includes the .set_config() refactoring of the
   GPIO chips, so that they pass a generic configuration for
   things like debouncing and single ended (typically open
   drain). This change has also been merged in an immutable
   branch to the GPIO tree.
 
 - Take hogs with a delayed work, so that we finalize probing
   a pin controller before trying to get any hogs.
 
 - For pin controllers putting all group and function definitions
   into the device tree, we now have generic code to deal with
   this and it is used in two drivers so far.
 
 - Simplifications of the pin request conflict check.
 
 - Make dt_free_map() optional.
 
 Updates to drivers:
 
 - pinctrl-single now use the generic helpers to generate dynamic
   group and function tables from the device tree.
 
 - Texas Instruments IOdelay configuration driver add-on to
   pinctrl-single.
 
 - i.MX: use radix trees to store groups and functions, use the new
   generic group and function helpers to manage them.
 
 - Intel: add support for hardware debouncing and 1K pull-down.
   New subdriver for the Gemini Lake SoC.
 
 - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
   MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
 
 - Aspeed: use syscon cross-dependencies to set up related bits in
   the LPC host controller and display controller.
 
 - Aspeed: finalize G4 and G5 support. Fix mux configuration on
   GPIOs. Add banks Y, Z, AA, AB and AC.
 
 - AMD: support additional GPIO.
 
 - STM32: set this controller to strict muxing mode.
   STM32H743 MCU support.
 
 - Allwinner sunxi: deep simplifications on how to support
   subvariants of SoCs without adding to much SoC-specific data
   for each subvariant, especially for sun5i variants. New driver
   for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
   variants with the new variant framework.
 
 - Mvebu: simplifications to use a MMIO and regmap abstraction.
   New subdrivers for the 98DX3236, 98DX5241 SoCs.
 
 - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
   SoC driver to access regmaps. Add infrastructure for pin-bank
   retention control. Clean out the pin retention control from
   arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
   in the Samsung pin control driver(s).
 
 - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
 
 - Qualcomm: use raw spinlock variants: this makes the qualcomm
   driver realtime-safe.
