I am a bit confused of what is exactly wrong or needs fixing. The code
organization is so that the file ti-bandgap.c adds the support for TI
Bandgap IP. It is not aware of thermal framework. And the
ti-thermal-common.c file is expected to talk to thermal framework. Can
you please elaborate a bit more why this split is hurting you?
