Yep, the CPU and DDR controller have temperatur sensors and there are
already thermal zones for them. We have the fan linked to the policies
in our vendor DTS overlay. For now I didn't want to include that here,
mainly because there are no labels in the fsl-ls1028a.dtsi for the
thermal zone/cooling maps/trips. But this is still on my TODO, when
this series finally make it into the kernel ;)
