Hi Sergey, these changes affect the clock tree and have to be reviewed and merged by the respective maintainers if they think the changes can be accepted. I don't see any reason why we should, if ACK'ed, take them in the PCI tree, this series does not apply changes to the PCI tree at all and you don't need it as a base for future to-be-merged PCI patches either. So in short, this series has to go through the usual clock tree review process.
