    Pull pin control updates from Linus Walleij:
     "This is the bulk of pin control changes for the v5.3 kernel cycle:
    
      Core changes:
    
       - Device links can optionally be added between a pin control producer
         and its consumers. This will affect how the system power management
         is handled: a pin controller will not suspend before all of its
         consumers have been suspended.
    
         This was necessary for the ST Microelectronics STMFX expander and
         need to be tested on other systems as well: it makes sense to make
         this default in the long run.
    
         Right now it is opt-in per driver.
    
       - Drive strength can be specified in microamps. With decreases in
         silicon technology, milliamps isn't granular enough, let's make it
         possible to select drive strengths in microamps.
    
         Right now the Meson (AMlogic) driver needs this.
    
      New drivers:
    
       - New subdriver for the Tegra 194 SoC.
    
       - New subdriver for the Qualcomm SDM845.
    
       - New subdriver for the Qualcomm SM8150.
    
       - New subdriver for the Freescale i.MX8MN (Freescale is now a product
         line of NXP).
    
       - New subdriver for Marvell MV98DX1135.
    
      Driver improvements:
    
       - The Bitmain BM1880 driver now supports pin config in addition to
         muxing.
    
       - The Qualcomm drivers can now reserve some GPIOs as taken aside and
         not usable for users. This is used in ACPI systems to take out some
         GPIO lines used by the BIOS so that noone else (neither kernel nor
         userspace) will play with them by mistake and crash the machine.
    
       - A slew of refurbishing around the Aspeed drivers (board management
         controllers for servers) in preparation for the new Aspeed AST2600
         SoC.
    
       - A slew of improvements over the SH PFC drivers as usual.
    
       - Misc cleanups and fixes"
