[PATCH 0/5] intel_th: Fixes for v6.14

[Alexander Shishkin]

Hi Greg,

Here are 5 patches that I'd like to get into this cycle; 3 are new PCI
IDs and 2 are kernel-doc warning fixes. Please take a look and consider
applying.

Alexander Shishkin (3):
  intel_th: msu: Fix less trivial kernel-doc warnings
  intel_th: pci: Add Panther Lake-H support
  intel_th: pci: Add Panther Lake-P/U support

Andy Shevchenko (1):
  intel_th: msu: Fix kernel-doc warnings

Pawel Chmielewski (1):
  intel_th: pci: Add Arrow Lake support
