arnd, olof, soc, robh+dt, krzysztof.kozlowski+dt, joel, andrew
These patches change the GPIO table, ADC channel configuration and
I2C bus configuration of the devicetree for the X570D4U BMC as part of
ongoing efforts to support OpenBMC on this platform.
Changes since v1:
- Fixed warnings indicated by checkpatch.pl
- Change commit message of ADC channels commit to match imperative mood
- Restructure GPIO table to better match other ASPEED devices
- Clarify naming scheme better
Best regards,
Renze Nicolai

It might be helpful to weigh in on that document with your ideas.
