Subject: [PATCH v3 0/4] Add support for tsens controller reinit via trustzone
Changes since v2:
-----------------
- v2 can be viewed here: https://lore.kernel.org/linux-arm-msm/20220724122424.2509021-1-bhupesh.sharma@linaro.org/
- Dropped sm6375 specific patch from v3, as suggested by Konrad.
- Rebased on latest linux-next (master branch) tip.
Changes since v1:
-----------------
- v1 can be viewed here: https://lore.kernel.org/linux-arm-msm/20220701145815.2037993-1-bhupesh.sharma@linaro.org/
- Addressed several comments from Bjorn regarding locking, serialization
etc received on v1.
- Addressed Konrad's concerns about the tsens controller found on sm6375
SoC which seems to start in a bad state or is disabled when entering
the linux world.
- This series would depend on sm6375 tsens controller changes being
added by Konrad. It is based on linux-next (master branch) tip.
Some versions of Qualcomm tsens controller might enter a
'bad state' causing sensor temperatures/interrupts status
to be in an 'invalid' state.
It is recommended to re-initialize the tsens controller
via trustzone (secure registers) using scm call(s) when that
happens.
This patchset adds the support for the same.
