Merge tag 'aspeed-4.17-devicetree' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joel/aspeed into next/dt

Pull "ASPEED device tree updates for 4.17" from Joel Stanley:

Updates to OpenPower BMC systems:

 A number of updates to use recently merged drivers, including moving to
 upstreamed IPMI BT nodes, a temp sensor for Romulus, and adding
 simple-reset for UARTs.

 This includes more of Palmetto's device tree, so that it's ever so
 close to booting the host with an upstream kernel.

New machines:

 Add Qualcomm Centriq ARM64 server reference platform, which will run
 OpenBMC on an AST2500.
