From b2cc26af46b4edada51449135b805706c71d73c8 Mon Sep 17 00:00:00 2001 From: Robert Lippert Date: Tue, 16 Apr 2019 09:21:51 -0700 Subject: ARM: dts: aspeed: zaius: fixed I2C bus numbers for pcie slots 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.
