> 
> Firmware driver enables APU to communicate to PMUFW(Platform
> Management Unit) via ATF by using SMC instructions. This patchset is adding
> support for base firmware driver with query and clock control APIs. More API
> support will be added with incremental patchsets along with their user driver.
