Would it be possible to enable COMPILE_TEST?
Do you means change to "depends on (MTK_DVFSRC && OF) || COMPILE_TEST" ?
Yeah, there is a stub for mtk_dvfsrc_send_request(). Maybe we could even change
it for INTERCONNECT_MTK to something like:
depends on ARCH_MEDIATEK || COMPILE_TEST
Will this work?
Thanks,
