Linus Torvalds bbfe0d6b8b This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.
 
 Core changes:
 
 - Support hierarchical GPIO irqchips. We now have three
   consumers that can use this: Intel IXP4xx, ThunderX and
   Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
   code has been long in the making and hashed out so it should
   be easily adaptable for all hierarchical irqchip parents.
   The code only gets compiled in if hierarchical irqchip
   is used at the topmost irq controller at least, as the
   hierarchical irqchip requires strict hierarchy all the
   way up in the system.
 
 - Determine the need for a "valid_mask" for GPIO lines on the
   gpio_chip and conversely for the "valid_mask" for the GPIO
   interrupt chip interrupt lines by looking for a
   .init_valid_mask() callback in the main chip or GPIO interrupt
   chip respectively. Allocate it with bitmap_alloc().
 
 - Isolate the device tree/open firmware GPIO description code
   out in its own file properly.
 
 - Isolate the ACPI GPIO description code out in its own file
   properly.
 
 - Drop a whole lot of #ifdef:s in the main includes: it does
   not hurt to keep the include items around, and we get
   quicker and clearer compile failures if the appropriate
   kernel symbols are not selected for drivers.
 
 New/deleted drivers:
 
 - New driver for Aspeed SGPIO.
 
 - The KS8695 driver is deleted as the platform gets deleted
   from arch/arm in this kernel cycle.
 
 - The Cirrus Logic Madera driver now supports CS47L92 and
   CS47L15.
 
 - The Freescale MPC8xxx now supports LS1028A and LS1088A.
 
 Driver improvements:
 
 - We pass the GPIO irqchip intialization by directly filling
   in the struct instead of using set-up functions (the new
   way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
   ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
 
 Out-of-band changes:
 
 - Fix a GPIO header inclusion in Unicore - no response from
   maintainer.
 
 - Drop FMC subsystem from MAINTAINERS - was deleted in the
   GPIO tree last cycle so let's mop up the shards.
