[PATCH 0/3] Add support for tsens controller reinit via trustzone

[Bhupesh Sharma]

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.
