Subject: [PATCH v5 0/2] thermal: mediatek: add support for MT7986 and MT7981
Message-ID: <cover.1674055882.git.daniel@makrotopia.org>

As requested in a previous review, first convert the if-else selection
of the raw_to_mcelsius_* function to instead use a function pointer
added to struct mtk_thermal. Then add thermal support for the MT7986
SoC which can also be used on MT7981.

Device Tree bindings have already been merged[1].

Changes since v4: Only use switch statement where requested[2] and keep
if-else logic in other places.

When submitting v3, it looked like the patch series submitted by Amjad
Ouled-Ameur ("thermal: mediatek: Add support for MT8365 SoC"[3]) which
also adds this function pointer would be merged first. However, a
re-spin of this series addressing the comments it has received has not
yet been submitted. The change introducing the raw_to_mcelsius function
pointer is hence being applied independently.

Changes since v2: Rebase on top of pending patch introducing
raw_to_mcelsius function pointer.
Drop left-over macro extracting the unused adc_oe field.
Use switch (...) instead of if-else-if-else-... statements.
For now, return -EINVAL as default in case of unknown version. Imho
this should be BUG(), as this version is only defined within this
driver.

Changes since v1: Drop use of adc_oe field in efuse, Henry Yen
confirmed its use has been dropped intentionally in MTK SDK as well.
