Linus Torvalds 3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be
   phased over to use pin control. We do not yet provide a
   userspace ABI for this pull up-down setting but I suspect
   the makers are going to ask for it soon enough. PCA953x
   is the first user of this new API.
 
 - The GPIO mockup driver has been revamped after some
   discussion improving the IRQ simulator in the process.
   The idea is to make it possible to use the mockup for
   both testing and virtual prototyping, e.g. when you do
   not yet have a GPIO expander to play with but really
   want to get something to develop code around before
   hardware is available. It's neat. The blackbox testing
   usecase is currently making its way into kernelci.
 
 - ACPI GPIO core preserves non direction flags when updating
   flags.
 
 - A new device core helper for devm_platform_ioremap_resource()
   is funneled through the GPIO tree with Greg's ACK.
 
 New drivers:
 
 - TQ-Systems QTMX86 GPIO controllers (using port-mapped
   I/O)
 
 - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
 
 - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
 
 - Fintek F81804 & F81966 subvariants.
 
 - PCA953x now supports NXP PCAL6416.
 
 Driver improvements:
 
 - IRQ support on the Nintendo Wii (Hollywood) GPIO.
 
 - get_direction() support for the MVEBU driver.
 
 - Set the right output level on SAMA5D2.
 
 - Drop the unused irq trigger setting on the Spreadtrum
   driver.
 
 - Wakeup support for PCA953x.
 
 - A slew of cleanups in the various Intel drivers.
