Merge tag 'powerpc-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc...

Pull powerpc updates from Michael Ellerman:

 - Add initial support to recognise the HeXin C2000 processor.

 - Add papr-vpd and papr-sysparm character device drivers for VPD &
   sysparm retrieval, so userspace tools can be adapted to avoid doing
   raw firmware calls from userspace.

 - Sched domains optimisations for shared processor partitions on
   P9/P10.

 - A series of optimisations for KVM running as a nested HV under
   PowerVM.

 - Other small features and fixes.
