Subject: [PATCH v3 0/2] drivers: thermal: intel: Use model-specific bitmasks for temperature registers

Hi,

Here is v3 of the patchset to use model-specific bitmasks to read TCC
offset and the digital temperature readout of IA32_[PACKAGE]_THERM_STATUS.

You can read the details and motivation in the cover letter of v1[1]. V2
is here [2].

Changes since v2:
 * Dropped patch 3/3 ("hwmon: (coretemp) Extend the bitmask to read
   temperature to 0xff") as it has been merged in v6.10-rc1.
 * Used the new X86_MATCH_VFM() macro. (Rafael)
 * Added Reviewed-by tags from Rui. Thanks!
 * Rebased on Rafael's testing branch (based on v6.10-rc3).

I have tested these patches on Alder Lake, Meteor Lake, and Grand Ridge
systems.

These patches apply cleanly on top of the `testing` branch of the linux-pm
repository.

Thanks and BR,
Ricardo
