From 2f60dd50769efcd6eedd0dc6b3f419cdd1f1f1fa Mon Sep 17 00:00:00 2001 From: Luben Tuikov Date: Wed, 19 Jan 2022 20:20:53 -0500 Subject: drm/amd: Expose the FRU SMU I2C bus Expose both SMU I2C buses. Some boards use the same bus for both the RAS and FRU EEPROMs and others use different buses. This enables the additional I2C bus and sets the right buses to use for RAS and FRU EEPROM access.
