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.
