Linus Torvalds 828907ef25 This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
 
 - The userspace API KFIFOs have been imoproved with locks that
   do not block interrupts. This makes us better at getting
   events to userspace without blocking or disturbing new events
   arriving in the same time. This was reviewed by the KFIFO
   maintainer Stefani. This is a generic improvement which
   paves the road for similar improvements in other subsystems.
 
 - We provide a new ioctl() for monitoring changes in the line
   information, such as when multiple clients are taking lines
   and giving them back, possibly reconfiguring them in the
   process: we can now monitor that and not get stuck with stale
   static information.
 
 - An example tool 'gpio-watch' is provided to showcase this
   functionality.
 
 - Timestamps for events are switched to ktime_get_ns() which is
   monotonic. We previously had a 'realtime' stamp which could
   move forward and *backward* in time, which probably would just
   cause silent bugs and weird behaviour. In the long run we
   see two relevant timestamps: ktime_get_ns() or the timestamp
   sometimes provided by the GPIO hardware itself, if that
   exists.
 
 - Device Tree overlay support for GPIO hogs. On systems that
   load overlays, these overlays can now contain hogs, and will
   then be respected.
 
 - Handle pin control interaction with nonexisting pin ranges
   in the GPIO library core instead of in the individual
   drivers.
 
 New drivers:
 
 - New driver for the Mellanox BlueField 2 GPIO controller.
 
 Driver improvements:
 
 - Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
   MMIO GPIO library and use this flag in the MT7621 driver.
 
 - Texas Instruments OMAP CPU power management improvements,
   such as blocking of idle on pending GPIO interrupts.
