Merge tag 'aspeed-4.16-devicetree' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joel/aspeed into next/dt

Pull "ASPEED device tree updates for 4.16" from Joel Stanley:

Clock driver support:

 Rework all platforms to use proper clock bindings. Linux should now boot
 upstream kernels on ast2400 and ast2500 platforms without out of tree
 patches.

New systems:

 Witherspoon: OpenPower Power9 server manufactured by IBM that uses the ASPEED ast2500
 Zaius: OpenPower Power9 server manufactured by Invatech that uses the ASPEED ast2500
 Q71L: Intel Xeon server manufactured by Qanta that uses the ASPEED ast2400

 We also see updates to the Palmetto and Romulus systems to bring them in
 line with the functionality of those above.

 The systems take advantage of recently added drivers for LPC Snoop
 device and the PWM/Tachometer fan controller.

OpenBMC flash layout:

 The flash layout used OpenBMC systems is added and the device trees now
 use it.
