Hello ARM Maintainers,

Here are the ASPEED device tree updates for 4.19. No new machines this time
around, but we now have some FSI (the bus between the BMC and the PowerPC host)
descriptions, and USB support.

The following changes since commit 7daf201d7fe8334e2d2364d4e8ed3394ec9af819:

  Linux 4.18-rc2 (2018-06-24 20:54:29 +0800)

are available in the Git repository at:

  ARM: dts: aspeed: Add Power9 CFAM description (2018-07-25 17:43:36 +0930)

----------------------------------------------------------------
ASPEED device tree updates for 4.19

 - New support for the ASPEED USB host controller and USB vhub (device)
 support

 - Descriptions for the FSI bus and hardware inside the Power8/Power9
 processors that are accessed over this bus. This includes the ColdFire
 processor that is part of the ASPEED SoC and is used to offload the FSI
 bit-banging

 - Small fixes:
  * pwm/tach clock
  * Romulus framebuffer location

I had some feedback on one of these patches, it should be reworked before we
merge it. See separate email as reply to the actual patch.

If you prefer, you can send a branch without that contents for merging now, so
the rest of it isn't held up.

No worries. I have sent a pull request without the FSI changes.

Thanks for taking a close look!

Cheers,
