Subject: [Patch v2 1/3] thermal: qcom: lmh: Add support for sm8150
Add compatible to support LMh for sm8150 SoC.
sm8150 does not require explicit enabling for various LMh subsystems.
Add a variable indicating the same as match data which is set for sdm845.
Execute the piece of code enabling various LMh subsystems only if
enable algorithm match data is present.
Signed-off-by: Thara Gopinath <thara.gopinath@...aro.org>
---
v1->v2:
- Added LMH_ENABLE_ALGOS of_device_id match data to indicate
whether LMh subsytems need explicit enabling or not.
