From: Keerthy <[email protected]> Patch adds hwmod entry for 4460 thermal sensor module. Thermal sensor module is part of Control module sharing its address space and clocked via Bandgap Functional Clock. Adding a seperate hwmod entry for thermal sensor will enable thermal sensor driver to manage its clock cleanly using PM runtime interfaces.
