Merge tag 'gpio-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.6 kernel cycle.

  This is a pretty calm cycle so far, nothing special going on really.
  Some more changes will come in from the irqchip and pin control trees.

  I also deleted an orphan include file for FMC that was dangling since
  subsystem was removed.

  Core changes:

   - Document the usecases for the kernelspace vs userspace handling of
     GPIOs.

   - Handle MSI (message signalled interrupts) properly in the core
     hierarchical irqdomain code.

   - Fix a rare race condition while initializing the descriptor array.

  New drivers:

   - Xylon LogiCVC GPIO driver.

   - WDC934x GPIO controller driver.

  Driver improvements:

   - Implemented suspend/resume in the Tegra driver.

   - MPC8xx edge detection fixup.

   - Properly convert ThunderX to use hierarchical irqdomain with
     GPIOLIB_IRQCHIP on top of the revert of the previous buggy
     switchover. This time it works (hopefully).

  Misc:

   - Drop a FMC remnant file <linux/ipmi-fru.h>

   - A slew of fixes"

 ideally have no use or idea of the global GPIO numberspace that has/was
 used in the inception of the GPIO subsystem.
 
+The numberspace issue is the same as to why irq is moving away from irq
+numbers to IRQ descriptors.
+
+The underlying motivation for this is that the GPIO numberspace has become
+unmanageable: machine board files tend to become full of macros trying to
+establish the numberspace at compile-time, making it hard to add any numbers
+in the middle (such as if you missed a pin on a chip) without the numberspace
+breaking.
+
+Machine descriptions such as device tree or ACPI does not have a concept of the
+Linux GPIO number as those descriptions are external to the Linux kernel
+and treat GPIO lines as abstract entities.
+
+The runtime-assigned GPIO numberspace (what you get if you assign the GPIO
+base as -1 in struct gpio_chip) has also became unpredictable due to factors
+such as probe ordering and the introduction of -EPROBE_DEFER making probe
+ordering of independent GPIO chips essentially unpredictable, as their base
+number will be assigned on a first come first serve basis.
+
+The best way to get out of the problem is to make the global GPIO numbers
+unimportant by simply not using them. GPIO descriptors deal with this.
