Merge tag 'aspeed-5.15-devicetree' of git://git.kernel.org/pub/scm/linux/kernel/git/joel/bmc into arm/dt

ASPEED device tree updates for 5.15

 - New machines

  * Facebook's Cloudripper
  * Facebook's Elbert
  * Facebook's Fuji

  All three carry the description of "Facebook's next generation switch
  platform with an AST2600 BMC integrated for health monitoring
  purpose."

  They share a 128 MB SPI NOR flash layout that is also used by some
  older platforms.

  * Inspur's NF5280M6, an x86 platform server with an AST2500-based BMC

 - SGPIO updates including AST2600 support

 - GPIO descriptions for the IBM AST2600 machines

 - Pinctrl fix

 - Updates to Facebook's AST2500 based machines

+title: Aspeed SGPIO controller
+
+maintainers:
+  - Andrew Jeffery <[email protected]>
+
+description:
+  This SGPIO controller is for ASPEED AST2400, AST2500 and AST2600 SoC,
+  AST2600 have two sgpio master one with 128 pins another one with 80 pins,
+  AST2500/AST2400 have one sgpio master with 80 pins. Each of the Serial
+  GPIO pins can be programmed to support the following options
+  - Support interrupt option for each input port and various interrupt
+    sensitivity option (level-high, level-low, edge-high, edge-low)
+  - Support reset tolerance option for each output port
+  - Directly connected to APB bus and its shift clock is from APB bus clock
+    divided by a programmable value.
+  - Co-work with external signal-chained TTL components (74LV165/74LV595)
