Bug Description
[Impact]
The i2c input frequency is currently hardcoded in the driver. This may not match the actual frequency used by the platform. Upstream has updated the driver to pull the frequency from firmware.
[Test Case]
The updated driver will detect the CAV9007 ACPI ID:
ubuntu@starbuck:~$ dmesg | grep xlp9xx-i2c
[ 47.723562] xlp9xx-i2c CAV9007:02: i2c transfer timed out!
The old driver will not claim this device.
[Regression Risk]
The changes are restricted to a driver that appears to be only used on MIPS platforms (which we don't support) and Cavium ThunderX2 systems that we've specifically tested upon.
