Subject: [PATCH v2 0/2] thermal: rcar_gen3: Use temperature approximation from datasheet
Date: Wed, 27 Mar 2024 14:30:11 +0100 [thread overview]
Message-ID: <20240327133013.3982199-1-niklas.soderlund+renesas@ragnatech.se> (raw)
Hello,
When the driver was first added the temperature approximation was
reversed engineered from an out-of-tree driver as the datasheets of the
time did not contain this information. Recent datasheets, both Gen3 and
Gen4, now contains this information.
This series changes the temperature approximation formula to match
what's described in the datasheets. It has been tested on both Gen3 and
Gen4 with minimal changes in temperatures reported.
Patch 1 is a cleanup making the scope of a constant more clear. Patch
2 is the real work changing the approximation formula.
Compared to v1 patch 3/3 have been squashed intro v2 patch 2/2. This is
due to a suggestion from Geert where the precision in approximation
could be increased while removing the need for the changed done in v1
3/3, thanks Geert!
See individual patches for detailed changelog.
