Subject: [PATCH 0/3] Add support for tsens controller reinit via trustzone
Date: Fri, 1 Jul 2022 20:28:12 +0530 [thread overview]
Message-ID: <20220701145815.2037993-1-bhupesh.sharma@linaro.org> (raw)
Some versions of QCoM 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.
