intel-pinctrl for v5.9-1 

* New driver for Emmitsburg
 * New driver for Tiger Lake-H
 * Part 3 of Cherryview driver clean up
 * Fix a glitch on Baytrail platforms
 
 The following is an automated git shortlog grouped by driver:
 
 ARM/orion/gpio:
  -  Make use of for_each_requested_gpio()
 
 at91:
  -  Make use of for_each_requested_gpio()
 
 baytrail:
  -  Use fallthrough pseudo-keyword
  -  Fix pin being driven low for a while on gpiod_get(..., GPIOD_OUT_HIGH)
  -  Drop no-op ACPI_PTR() call
 
 cherryview:
  -  Re-use data structures from pinctrl-intel.h (part 3)
  -  Convert chv_writel() to use chv_padreg()
  -  Introduce helpers to IO with common registers
  -  Introduce chv_readl() helper
 
 gpio:
  -  xra1403: Make use of for_each_requested_gpio()
  -  mvebu: Make use of for_each_requested_gpio()
 
 gpiolib:
  -  Introduce for_each_requested_gpio_in_range() macro
 
 intel:
  -  Add Intel Emmitsburg pin controller support
  -  Make use of for_each_requested_gpio_in_range()

  -  Split intel_config_get() to three functions
  -  Drop the only label in the code for consistency
  -  Get rid of redundant 'else' in intel_config_set_debounce()
  -  Make use of IRQ_RETVAL()
  -  Reduce scope of the lock
  -  Disable input and output buffer when switching to GPIO
  -  Allow drivers to define ACPI address space ID
  -  Allow drivers to define total amount of IRQs per community
 
 lynxpoint:
  -  Drop no-op ACPI_PTR() call
  -  Introduce helpers to enable or disable input
