    Linus Torvalds authored
    Pull GPIO updates from Linus Walleij:
     "This is the bulk of GPIO changes for the v4.17 kernel cycle:
    
      New drivers:
    
       - Nintendo Wii GameCube GPIO, known as "Hollywood"
    
       - Raspberry Pi mailbox service GPIO expander
    
       - Spreadtrum main SC9860 SoC and IEC GPIO controllers.
    
      Improvements:
    
       - Implemented .get_multiple() callback for most of the
         high-performance industrial GPIO cards for the ISA bus.
    
       - ISA GPIO drivers now select the ISA_BUS_API instead of depending on
         it. This is merged with the same pattern for all the ISA drivers
         and some other Kconfig cleanups related to this.
    
      Cleanup:
    
       - Delete the TZ1090 GPIO drivers following the deletion of this SoC
         from the ARM tree.
    
       - Move the documentation over to driver-api to conform with the rest
         of the kernel documentation build.
    
       - Continue to make the GPIO drivers include only
         <linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we
         want to get rid of.
    
       - Managed to remove VLA allocation from two drivers pending more
         fixes in this area for the next merge window.
    
       - Misc janitorial fixes"
