Merge tag 'aspeed-5.5-devicetree' of git://git.kernel.org/pub/scm/linux/kernel/git/joel/aspeed into arm/dt

ASPEED device tree updates for 5.5

 - Lots of work on the AST2600 boards as bringup continues. There's the
 eval board, and two IBM boards called Tacoma and Rainier

 - A new flash layout for OpenBMC systems with larger flashes

 - Better support for the MAC clocking when talking to a NCSI device,
 making Linux less reliant on u-boot having done the correct thing

 - LED fixes for vesin and fp5280g2

 - SGPIO support

 - Facebook network BMC cleanup with the common hardware moved to a
 shared dtsi
