Hi,
This series contains three updates to the Zaius ASPEED device-tree to
add voltrage regulators, and update addresses and aliases. The Infineon
and Intersil drivers are staged on hwmon-next, and the trivial device
dt-bindings changed are up for review.
Maxim Sloyko (1):
ARM: dts: aspeed: zaius: add Infineon and Intersil regulators
Robert Lippert (2):
ARM: dts: aspeed: zaius: update 12V brick I2C address
ARM: dts: aspeed: zaius: fixed I2C bus numbers for pcie slots

The I2C address of the brick is different depending on the board SKU.
Update the values to instantiate addresses which work for most boards.

2.21.0.392.gf8f6787159e-goog
From: Robert Lippert <[email protected]>
The change to include ibm-power9-cfam.dtsi resulted in a renumbering
of all of the I2C bus numbers behind the on-board muxes. This breaks
some tools which have hardcoded the bus numbers.
Add device tree aliases for the I2C buses routed through the PCIe slots
so that they return to their former numbers before the cfam change.

Applied to the aspeed SoC tree, thanks Patrick.
