    Pull GPIO updates from Linus Walleij:
     "This is the bulk of GPIO changes for the v5.8 kernel cycle.
    
      Core changes:
    
       - A new GPIO aggregator driver has been merged: this can join a few
         select GPIO lines into a new aggregated GPIO chip. This can be used
         for security: a process can be granted access to only these lines,
         for example for industrial control. Another way to use this is to
         reexpose certain select lines to a virtual machine or container.
    
       - Warn if the gpio-line-names is too long in he DT parser core.
    
       - GPIO lines can now be looked up by line name in addition to being
         looked up by offset.
    
      New drivers:
    
       - A new generic regmap GPIO driver has been merged. Too many regmap
         drivers are starting to look like each other so we need to create
         some common ground and try to move drivers over to using that.
    
       - The F7188X driver now supports F81865.
    
      Driver improvements:
    
       - Large improvements to the PCA953x expander, get multiple lines and
         several cleanups.
    
       - Large improvements to the DesignWare DWAPB driver, and Sergey Semin
         has volunteered to maintain it.
    
       - PL061 can now be built as a module, this is part of a bigger effort
         to make the ARM platforms more modular"
