Merge branch 'thermal-intel'
Merge updates of Intel thermal drivers for 7.1:
- Replace cpumask_weight() in intel_hfi_offline() with cpumask_empty()
which is generally more efficient (Yury Norov)
- Add support for reading DDR data rate from PCI config space on Nova
Lake platforms to the int340x thermal driver (Srinivas Pandruvada)
* thermal-intel:
thermal: intel: hfi: use cpumask_empty() in intel_hfi_offline()
thermal: intel: int340x: Read DDR data rate for Nova Lake
