Subject: [PATCH v2 2/3] thermal: intel: intel_tcc_cooling: Use a model-specific bitmask for TCC offset
Date: Thu, 25 Apr 2024 10:13:10 -0700
Message-Id: <20240425171311.19519-3-ricardo.neri-calderon@linux.intel.com>
In-Reply-To: <20240425171311.19519-1-ricardo.neri-calderon@linux.intel.com>
References: <20240425171311.19519-1-ricardo.neri-calderon@linux.intel.com>
Precedence: bulk

The TCC offset field in the register MSR_TEMPERATURE_TARGET is not
architectural. The TCC library provides a model-specific bitmask. Use it to
determine the maximum TCC offset.
