Thanks, Bhupesh
Changes since v3: ----------------- - v3 can be viewed here: https://lore.kernel.org/linux-arm-msm/20220804054638.3197294-1-bhupesh.sharma@linaro.org/ - Addressed review comments from Bjorn regarding early exit paths, spin lock being held while returning from func, etc. - Also added Bjorn's R-Bs for v3 patches. - Rebased on latest linux-next (master branch) tip. 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.
