Hi, This series implements pnv-phb4 user devices for the powernv9 machine. It also includes a couple of pnv-phb3 and pnv-phb3-root-port fixes that were also applied for the pnv4 equivalents.
During the enablement I had to rollback from the previously added support for user creatable pnv-phb4-pec devices. The most important reason is user experience. PEC devices that doesn't spawn the PHB devices will be just a placeholder to add PHBs, having no use of their own as far as the user sees it. From this standpoint it makes more sense to just create all PECs and attach the PHBs the user wants on them. Patch 14 also describes technical reasons to rollback this support. The series is rebased using Cedric's 'powernv-6.2' branch [1]i, which includes the '[PATCH 0/5] ppc/pnv: Preliminary cleanups before user created PHBs' patches [2].
